First, I created a simple program that playes media when you click on a button.
In my Main Activity class I have:
MediaPlayer mySound;
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mySound = MediaPlayer.create(this, R.raw.sleepnk);
}
Then I created the following:
public void playMusic(View view)
{
mySound.start();
}
Then in my XML file I created a button and added:
android:onClick="playMusic"
Now I am trying to add media to an app but it doesn't have something like:
<Button
android:id="#+id/button"
.
My goal is to add a media file to this "Tap to Start" invisible button in this new app but since there are no buttons in the xml file, I don't know where to attach my playMusic method to the Tap to Start button. I am including instances of Tap to Start button so you can see how it is acting as a button-
There is a strings.xml under values folder that contains:
<?xml version="1.0" encoding="utf-8"?>
<string name="app_name">Panoramik</string>
<string name="instruction_tap_start">Tap to start</string>
Then in the MainActivity.java file we have:
private View.OnClickListener mCameraOnClickListener = new View.OnClickListener() {
#Override
public void onClick(View v) {
if (mIsCapturing) {
//clear the flag to prevent the screen of being on
getWindow().clearFlags(android.view.WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
if (mDMDCapture.finishShooting()) {
mIsStitching = true;
mTextViewInstruction.setVisibility(View.INVISIBLE);
}
mIsCapturing = false;
setInstructionMessage(R.string.instruction_tap_start);
I am also including the code for "setInstructionMessage" method:
private void setInstructionMessage(int msgID)
{
if (mCurrentInstructionMessageID == msgID)
return;
RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(mDisplayMetrics.widthPixels, RelativeLayout.LayoutParams.WRAP_CONTENT);
params.addRule(RelativeLayout.CENTER_HORIZONTAL);
if (msgID == R.string.instruction_empty || msgID == R.string.instruction_hold_vertically || msgID == R.string.instruction_tap_start
|| msgID == R.string.instruction_focusing) {
params.addRule(RelativeLayout.CENTER_VERTICAL);
} else {
params.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM);
}
mTextViewInstruction.setLayoutParams(params);
mTextViewInstruction.setText(msgID);
mCurrentInstructionMessageID = msgID;
}
Can anyone tell me how I can attach my media file sleepnk to the Tap to Start invisible button?
EDIT: I basically want the app to say "Tap to Start" because the app is being created for the visually impaired. So if there is any other suggestion for the app to talk back to the user, feel free to comment
You should let the OS and TalkBack read the "android:contentDescription" attribute by assigning the string "Tap to Start" to whatever it is you want the user to touch. (Remembering to use a string resource so it can be translated/localized.)

I'm using Android Studio and trying to show some chosen Street View paths in VR. I already have Street View running well and now I'm trying to show it in VR.
I have put the com.google.vr.sdk.widgets.pano.VrPanoramaView in the layout and, inside onCreate in my class, referenced it to a VrPanoramaView variable through findViewById. Now I'm trying to show an image calling a method which I've defined in this class, loadPanoImage. This method loads an image from the storage and shows it through loadImageFromBitmap.
The problem is that it isn't able to show anything, even though I've followed a guide and I've done everything as showed. I've even tryed calling it in different parts of the code (before doing any other action, on clicking a button, before and after showing streetview) but I can't understand why it isn't working and how will I be able to use it to show images taken from StreetView (I don't know if I will be able to do it dinamically or I should download them and put them in the storage).
I'm putting part of the code for reference:
public class VrExperience extends FragmentActivity {
Button buttonCitta;
Button buttonMare;
Button buttonMontagna;
TextView titleTextView;
// George St, Sydney
private static final LatLng SYDNEY = new LatLng(-33.87365, 151.20689);
// LatLng with no panorama
private static final LatLng INVALID = new LatLng(-45.125783, 151.276417);
//VrPanoramaView is inserted in the layout
private VrPanoramaView panoWidgetView;
//StreetViewPanorama is another class in my project which shows Street View
private StreetViewPanorama mStreetViewPanorama;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_vrexperiences);
panoWidgetView = (VrPanoramaView) findViewById(R.id.pano_view);
panoWidgetView.setEventListener(new VrPanoramaEventListener());
//download image and show it, but it doesn't show anything
loadPanoImage();
titleTextView = (TextView) findViewById(R.id.titleTextView);
buttonCitta = (Button) findViewById(R.id.buttonCitta);
buttonCitta.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
if (!checkReady()) {
return;
}
titleTextView.setVisibility(View.GONE);
buttonCitta.setVisibility(View.GONE);
buttonMare.setVisibility(View.GONE);
buttonMontagna.setVisibility(View.GONE);
loadPanoImage(); //it doesn't show anything
mStreetViewPanorama.setPosition(SYDNEY);
loadPanoImage(); //it doesn't show anything
}
}};
//code for buttonMontagna and buttonMare as well, it's identical
SupportStreetViewPanoramaFragment streetViewPanoramaFragment =
(SupportStreetViewPanoramaFragment)
getSupportFragmentManager().findFragmentById(R.id.streetviewpanorama);
streetViewPanoramaFragment.getStreetViewPanoramaAsync(
new OnStreetViewPanoramaReadyCallback() {
#Override
public void onStreetViewPanoramaReady(StreetViewPanorama panorama) {
mStreetViewPanorama = panorama;
// Only set the panorama to INVALID on startup (when no panoramas have been
// loaded which is when the savedInstanceState is null).
if (savedInstanceState == null) {
mStreetViewPanorama.setPosition(INVALID);
}
}
});
}
/**
* When the panorama is not ready the PanoramaView cannot be used. This should be called on
* all entry points that call methods on the Panorama API.
*/
private boolean checkReady() {
if (mStreetViewPanorama == null)
return false;
return true;
}
/**
* Called when the Animate To Invalid button is clicked.
*/
public void onGoToInvalid(View view) {
if (!checkReady()) {
return;
}
mStreetViewPanorama.setPosition(INVALID);
}
//retrieves image from the assets folder and loads it into the VrPanoramaView
private void loadPanoImage() {
VrPanoramaView.Options options = new VrPanoramaView.Options();
InputStream inputStream = null;
AssetManager assetManager = getAssets();
try {
inputStream = assetManager.open("demo2.jpg");
options.inputType = VrPanoramaView.Options.TYPE_MONO;
panoWidgetView.loadImageFromBitmap(
BitmapFactory.decodeStream(inputStream), options
);
inputStream.close();
} catch (IOException e) {
Log.e("Fail", "Exception in loadPanoImage" + e.getMessage());
}
}
#Override
protected void onPause() {
panoWidgetView.pauseRendering();
super.onPause();
}
#Override
protected void onResume() {
super.onResume();
panoWidgetView.resumeRendering();
}
#Override
protected void onDestroy() {
panoWidgetView.shutdown();
super.onDestroy();
}
}
This is my layout:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/vrExperienceActivity"
android:layout_width="match_parent"

</LinearLayout>
EDIT: #LucioB
a) those are the places I've tried to call loadPanoImage, but neither of them showed anything. It acts as nothing happens calling that method, the program keeps going to the other tasks. I'd like for images to be shown directly in VR when a button is clicked, or if that isn't possible to add the classic cardboard button in Street View mode to pass to VR view.
b) I mean the code isn't doing what I expected it to do. I thought that once I created VrPanoramaView in the layout and used it to show an image through .loadImageFromBitmap it would have shown the image I loaded from asset (I have an image saved on the virtual SD), and that once I was able to do that for a single image I would have found a way to do it for a whole path.
The code doesn't give any exception, I think I'm making a logic mistake or I didn't understand how VR api work.
EDIT: I've found that the java code is working, the problem was in the layout which didn't permit to see VrPanoramaView because it was obscured by StreetViewPanorama
I am trying to display a dialog based on the number of clicks that have occurred. I have two little issues with it which I will explain below:
So I clear the data on my app so that the number of clicks starts on 0. Basically what I am trying to do is that when I access the class below, if the number of clicks = 4, 8 or 12, then output the relevant message associated to them in my if else statements. If it doesn't equal any of those numbers then for every 4 clicks (16, 20, 24 ,28 etc) display the default message of 'You are rewarded with a video.
So starting from fresh on zero clicks, when I navigate to this page I notice for each click (1,2,3,4 etc) it displays the default dialog message which is not what I require. I want it to display the messages for 4, 8, 12 which have their own specific messages and then there after (16, 20, 24, 28 etc) should display the general message.
What I have also noticed is that if I come out of the page by selecting the back button and then access the page again, every time the dialog appears it takes me many taps on the ok button for the dialog to close. Initially before I went back from the page it only took me one tap to close the dialog but when I re-enter the page then it takes many taps and I am not sure why.
How can these 2 issues be fixed?
Code below:
import java.util.Random;
public class Content extends AppCompatActivity {
Button backButton;
Button selectAnotherButton;
TextView clickCountText;
int getClickCountInt;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_content);
final SharedPreferencesManager prefManager = SharedPreferencesManager.getInstance(Content.this);
clickCountText = findViewById(R.id.click_count);
clickCountText.setText(Integer.toString(prefManager.getClicks()));
getClickCountInt = Integer.parseInt(clickCountText.getText().toString());
backButton = findViewById(R.id.button_back);
selectAnotherButton = findViewById(R.id.button_select_another);
setContent();
selectAnotherButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
clickCountText.setText(Integer.toString(prefManager.increaseClickCount()));
if (getClickCountInt == 4){
ShowRewardDialog("You are rewarded with a the yellow smiley face in the homepage");
} else if (getClickCountInt == 8) {
ShowRewardDialog("You are rewarded with a the green smiley face in the homepage");
} else if (getClickCountInt == 12) {
ShowRewardDialog("You are rewarded with a the red smiley face in the homepage");
} else {
for(int i = 0; i <= getClickCountInt; i+=4) {
ShowRewardDialog("You are rewarded with a video\"");
}
}
setContent();
}
});
backButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
finish();
}
});
}
private void ShowRewardDialog(String message) {
final Dialog dialog = new Dialog(Content.this);
dialog.setContentView(R.layout.custom_dialog);
SpannableString title = new SpannableString("YOU GAINED A REWARD");
title.setSpan(new ForegroundColorSpan(Content.this.getResources().getColor(R.color.purple))
, 0, title.length(), Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
// set the custom dialog components - text, image and button
TextView text = dialog.findViewById(R.id.dialog_text);
dialog.setTitle(title);
text.setText(message);
Button dialogButton = dialog.findViewById(R.id.dialog_button_OK);
// if button is clicked, close the custom dialog
dialogButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
dialog.dismiss();
}
});
dialog.show();
}
}
UPDATE
Ok to make it easier I will say what is the current problem and how I want it to work.
I have disabled the else statement for now in the Content class where it displays a generic message in the dialog box.
Ok so I have created a class for my Shared Preferences and I can get an instance of it from both the MainActivity class (this is my homepage) and Content class (this is second page).
Lets say the click counts starts on 0 (and I display this as a text) and I am on the homepage. When I select the jokes button from the homepage, I will navigate to the second page and the count starts at 1. If I select 'Select Another' button which is displayed in second page, then the count goes to 2 (as I can see by the text displayed), click again then three and click again it will go to 4 and the dialog box for count 4 is displayed. This works for when I go to 8 and 12 as well.
When I select the 'Back' button to go from second page to front page, I can see the count remains the same as the count displayed in the second page. E.g if count was set to 8 on page 2 and I click back, the homepage displays the count of 8 as well when I view the text.
This seems all well and good. However lets start again from 0. If I click on the jokes button then I am on 1, I select 'Select Another' button twice so the count is on 3 and then click back button. Count is currently on 3 when I view the homepage. If I click on the jokes button again then the count is on 4 which is correct, however the dialog for if count equals to 4 does not appear. However if I click on the 'Select Another' button 3 more times then it will display the dialog for 4. So it seems like the dialog will only appear for 4 if the 'Select Another' button is clicked four in a row, rather than how I want it which is if the total number of clicks count equals 4 then show the dialog.
What will I need to do to fix this?
Below is the code:

The first problem with your algorithm is that you're not adding the current clicks to your click count.
Inside the onClick of selectAnotherButton.setOnClickListener you should add a getClickCountInt++ (and dont forget to update clickCountText with this new value).
Also, on your onCreate you should get the value for getClickCountInt from SharedPreferences, and then use it to set the value on clickCountText, not the other way around.
This answear shows how to read/store data in SharedPreferences.
I'm working on an app that uses PayPal. I need to use the MPL, as opposed to the SDK, because my app needs to be able to implement third-party payments. I've followed various tutorials and created the code below. I don't get any compiler errors, and no log cat error, but when I run it and click on the "Pay with PayPal" button, nothing happens. Instead, I get ViewPostImeInputStage ACTION_DOWN when I click on the button or anywhere on the screen.
I have no idea why. Please help!
public class MainActivity extends Activity implements View.OnClickListener {
private CheckoutButton launchPayPalButton;
final static public int PAYPAL_BUTTON_ID = 10001;
private double _theSubtotal;
private double _taxAmount;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
initLibrary();
showPayPalButton();
}
private void showPayPalButton() {
LinearLayout linearLayout = new LinearLayout(this);
linearLayout.setOrientation(LinearLayout.VERTICAL);
ViewGroup.LayoutParams linearLayoutParam = new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT);
setContentView(linearLayout, linearLayoutParam);
LayoutParams lpView = new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
// Generate the PayPal checkout button and save it for later use
PayPal pp = PayPal.getInstance();
launchPayPalButton = pp.getCheckoutButton(this, PayPal.BUTTON_194x37, CheckoutButton.TEXT_PAY);
// The OnClick listener for the checkout button
launchPayPalButton.setOnClickListener(this);
// Add the listener to the layout
launchPayPalButton.setLayoutParams(lpView);
launchPayPalButton.setId(PAYPAL_BUTTON_ID);
linearLayout.addView(launchPayPalButton);
}
public void PayPalButtonClick(View arg0) {
PayPalPayment newPayment = new PayPalPayment();
newPayment.setSubtotal(new BigDecimal(_theSubtotal));
newPayment.setCurrencyType("USD");
newPayment.setRecipient("my#email.com");
newPayment.setMerchantName("My Company");
Intent paypalIntent = PayPal.getInstance().checkout(newPayment, this);
this.startActivityForResult(paypalIntent, 2);
}
public void initLibrary() {
PayPal pp = PayPal.getInstance();
if (pp == null) { // Test to see if the library is already initialized
// This main initialization call takes your Context, AppID, and target server
pp = PayPal.initWithAppID(this, "APP-80W284485P519543T", PayPal.ENV_NONE);
// Required settings:
// Set the language for the library
pp.setLanguage("en_US");
// Some Optional settings:
// Sets who pays any transaction fees. Possible values are:
// FEEPAYER_SENDER, FEEPAYER_PRIMARYRECEIVER, FEEPAYER_EACHRECEIVER, and FEEPAYER_SECONDARYONLY
pp.setFeesPayer(PayPal.FEEPAYER_EACHRECEIVER);
// true = transaction requires shipping
pp.setShippingEnabled(false);
}
}
#Override
public void onClick(View arg0){
PayPalButtonClick(arg0);
}
}
Probably because you haven't set the content view after super.oncreate() and since you're registering your activity as the on click listener, its responding to clicks from anywhere on the screen instead of just the button.
EDIT
Add an on click listener to the button like this
paypalButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View arg0) { PayPalButtonClick(arg0); }
});
and remove the implementation of the OnClickListener from your activity
ViewPostImeInputStage ACTION_DOWN is basically a condition when your layout is rejected and you are no longer be able to click on any clickable items.The solution for this is simple, just wrap your layout contents with a parent.
for ex:
if you have the xml with format as:
<LinearLayout <---root layout
..... contents here
</LinearLayout> <-- root layout end
change to
<FrameLayout <---root layout
<LinearLayout <-- parent wrap start
...
<!-- your content -->
</LinearLayout> <-- parent wrap end
</FrameLayout> <-- root layout end

I am trying to build an android app and I need a MultiSelectListPreference option in the settings menu. I have created a PreferenceActivity to handle this and I created a preferences.xml file as well, but I need to be able to load the list elements dynamically in the program. I know that I need to use the setEntries and setEntryValues methods to do this, but when I use these methods no exceptions are thrown and the title and summary of the MultiSelectListPreferenc show up but no elements appear.
I have verified that the arrays I am using to populate entries and entryValues are not empty by printing them out, as well as by printing out the result of getEntries() and getEntryValues() after having set them and both these show the entry list to be populated; however no elements show up.
My preferences.xml code:
<?xml version="1.0" encoding="utf-8"?>
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android">
<MultiSelectListPreference
android:key="markedApps"
android:title="Targeted Apps"
android:summary="Select apps to conditionally disable" />
</PreferenceScreen>
My AppSettings.java code:
public class AppSettings extends PreferenceActivity {
public static MultiSelectListPreference blocked;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
blocked = new MultiSelectListPreference(this);
getFragmentManager().beginTransaction().replace(android.R.id.content, new PrefFrag()).commit();
}
public static class PrefFrag extends PreferenceFragment {
#Override
public void onCreate(final Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
addPreferencesFromResource(R.xml.preferences);
MultiSelectListPreference blocked = (MultiSelectListPreference)findPreference("markedApps");
if (blocked == null)
Log.e("NullPointerException", "Blocked is null");
AppSelector.populateAppList();
CharSequence[] appNames = new CharSequence[AppSelector.Data.appNames.size()];
CharSequence[] allApps = new CharSequence[AppSelector.Data.allApps.size()];
int i = 0;
for (String appName : AppSelector.Data.appNames)
appNames[i++] = (CharSequence) appName;
i = 0;
for (String app : AppSelector.Data.allApps)
allApps[i++] = (CharSequence) app;
blocked.setEntries(appNames);
blocked.setEntryValues(allApps);
}
}
}
Thank you in advance for any help you provide.
Wow so I feel extremely stupid now. Turns out my problem was that I expected the list to show up under the title and summary whereas you actually have to click on the title and summary to make the list pop up.
I have this TextView in my application
<TextView
android:id="#+id/txtStatusMsg"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:paddingBottom="10dp"
android:paddingLeft="#dimen/feed_item_status_pad_left_right"
android:paddingRight="#dimen/feed_item_status_pad_left_right"
android:paddingTop="#dimen/feed_item_status_pad_top"
android:textIsSelectable="true"
/>
and its selectable ..when i select text and copy it i want to add extra text
example :
Test text
what i want is when i select the text and copy it :
Test text - Copied from xx app
how i can do it ?
You'll want to add a clipboardListener:
private boolean mSkipClip;
#Override
protected void onCreate(Bundle savedInstanceState) {
...
final ClipboardManager mClipboard = (ClipboardManager)mAct.getSystemService
(Context.CLIPBOARD_SERVICE);
mClipboard.addPrimaryClipChangedListener(new ClipboardManager
.OnPrimaryClipChangedListener() {
#Override
public void onPrimaryClipChanged() {
if (mSkipClip) {
mSkipClip = false;
} else {
// Append custom string
ClipData clipData = new ClipData(mClipboard.getPrimaryClip());
clipData.addItem(new ClipData.Item("Copied from xx app"));
mSkipClip = true;
mClipboard.setPrimaryClip(clipData);
}
}
});
}
Notes:
ClipData class which is available only since API 16.
Other classes and methods are available since API 11.
When you update the clipboard data, the listener is called again. mSkipClip helps the listener skip such callbacks.
When pausing your activity, make sure you remove the listener, as it will listen to clipboard activity on other activities and apps too.
