android switch intent dynamically

android switch intent dynamically - java

I am trying to create a main menu activity in android which dynamically selects the activity destination from its position on the page.
MainMenu.java
package com.verscreative.BowlTrack;
import android.content.Context;
import android.content.Intent;
import android.graphics.Color;
import android.os.Bundle;
import android.view.Gravity;
import android.view.View;
import android.view.ViewGroup;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.BaseAdapter;
import android.widget.GridView;
import android.widget.TextView;
import android.widget.Toast;
import com.actionbarsherlock.app.SherlockActivity;
import com.actionbarsherlock.view.Menu;
import com.actionbarsherlock.view.MenuInflater;
public class MainMenu extends SherlockActivity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main_menu);
GridView gridview = (GridView) findViewById(R.id.grid);
gridview.setAdapter(new HomeMenuAdapter());
gridview.setPadding(50, 40, 50, 40);
gridview.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View v, int position, long id) {
//Activities That are invoked by the click
String[] mActivitiesIds = {
getString(R.string.menu_launch_0),
getString(R.string.menu_launch_1),
getString(R.string.menu_launch_2),
getString(R.string.menu_launch_3),
getString(R.string.menu_launch_4),
getString(R.string.menu_launch_5)
};
String packageName = "com.verscreative.BowlTrack";
String className = mActivitiesIds[position]+".class";
//TODO: Switch Toast To Activity Intent
Intent i = new Intent();
i.setClassName(packageName, className);
try{
startActivity(i);
}catch(Exception e){
Toast t = Toast.makeText(getApplicationContext(), "Cannot Find Activity", Toast.LENGTH_LONG);
t.show();
}
}
});
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getSupportMenuInflater();
inflater.inflate(R.menu.main_menu, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(com.actionbarsherlock.view.MenuItem item) {
switch (item.getItemId()) {
case R.id.action_settings:
activateSettings();
return true;
default:
return super.onOptionsItemSelected(item);
}
}
public void activateSettings(){
Intent i = new Intent(this, SettingsActivity.class);
startActivity(i);
}
public class HomeMenuAdapter extends BaseAdapter {
public HomeMenuAdapter() {
}
public int getCount() {
return mThumbIds.length;
}
public Object getItem(int position) {
return null;
}
public long getItemId(int position) {
return 0;
}
// create a new ImageView for each item referenced by the Adapter
public View getView(int position, View convertView, ViewGroup parent) {
TextView tv;
if (convertView == null) {
tv = new TextView(getApplicationContext());
tv.setGravity(Gravity.CENTER | Gravity.BOTTOM);
tv.setPadding(0, 10, 0, 10);
} else {
tv = (TextView) convertView;
}
tv.setCompoundDrawablesWithIntrinsicBounds(0, mThumbIds[position], 0, 0);
tv.setText(mTextIds[position]);
tv.setHeight(300);
tv.setTextColor(Color.WHITE);
return tv;
}
// references to our images
private Integer[] mThumbIds = {
android.R.drawable.ic_menu_add,
android.R.drawable.ic_menu_view,
android.R.drawable.ic_menu_info_details,
android.R.drawable.ic_menu_close_clear_cancel,
android.R.drawable.ic_menu_close_clear_cancel,
android.R.drawable.ic_menu_preferences
};
private String[] mTextIds = {
getString(R.string.menu_item_0),
getString(R.string.menu_item_1),
getString(R.string.menu_item_2),
getString(R.string.menu_item_3),
getString(R.string.menu_item_4),
getString(R.string.menu_item_5)
};
}
}
However whatever I do it always says "Cannot Find Activity".
If I change:
String packageName = "com.verscreative.BowlTrack";
String className = mActivitiesIds[position]+".class";
Intent i = new Intent();
i.setClassName(packageName, className);
to for example:
Context packageName = MainMenu.this;
Class<ViewGamesActivity> className = ViewGamesActivity.class;
Intent i = new Intent();
i.setClass(packageName, className);
It works fine, but all options do the same thing!

Thanks to jimpanzer and sherif-elkhatib, I have combined your comments to find the answer.
The Answer is Changing:
String className = mActivitiesIds[position]+".class";
to this:
String className = "com.verscreative.BowlTrack."+mActivitiesIds[position];

I don't think you need to specify the .class
Try this
String className = mActivitiesIds[position];
Otherwise, a more efficient solution would be to have a 2D array as such :
Object[][] mActivitiesIds =
{
{ getString(R.string.menu_launch_0), Activity1.class }
{ getString(R.string.menu_launch_1), Activity1.class }
{ getString(R.string.menu_launch_2), Activity1.class }
{ getString(R.string.menu_launch_3), Activity1.class }
{ getString(R.string.menu_launch_4), Activity1.class }
{ getString(R.string.menu_launch_5) Activity1.class }
};
Then simply use mActivitiesIds[n][1] to get the class...

App crashing when attempting to add to ArrayAdapter

I am working on an assignment for school, the instructions are to create a Bookmark app with two activities, one named BookNote which must be a List Activity and another called ManageActivity.
BookNote is to populate the List Activity on startup with data read from a file, if no file is present an example bookmark is created. Bookmarks can be added, edited, and deleted, but all typing must be done in ManageActivity. Whenever Booknote handles the data returned from ManageActivity it should alter the list.
The code I have now has comments showing my intentions for each function, but my current problem is that everytime I return to BookNote from ManageActivity, the app crashes with the error "Attempt to invoke virtual method 'void android.widget.ArrayAdapter.insert(java.lang.Object, int)' on a null object reference" when attempting to add or insert a new bookmark object into the ArrayAdapter.

You are declaring a global and a local instance of adapter. In onCreate() method of BookNote Activity, remove the local instance. Change
ArrayAdapter adapter = new ArrayAdapter<Bookmark>(this, android.R.layout.simple_list_item_1, bookmarkList);
to
adapter = new ArrayAdapter<Bookmark>(this, android.R.layout.simple_list_item_1, bookmarkList);

You are not setting xml file which contains
book_layout.xml
<ListView android:id="#+id/android:list"
android:layout_width="fill_parent"
android:layout_height="fill_parent"/>
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.book_layout);
ArrayList<Bookmark> bookmarkList = readData();
ArrayAdapter adapter = new ArrayAdapter<Bookmark>(this, android.R.layout.simple_list_item_1, bookmarkList);
setListAdapter(adapter);

I WANT TO LOAD IMAGES ATLEAST IN THIS BASE... OR ANYOTHER THING...

There are lots of image loading library available for android.
Have a look at these

Method OnItemClickListener from JSONParser override OnItemLongClickListener from another activity

I'm trying to create the favorites list from Json Objects which I received by URL.
When I got Json array, I defined methods OnItemLongClickListener and OnItemClickListener that get different things:
The OnItemClickListener method has to open another activity with description of product
The OnItemLongClickListener method has to add product to favorite list
The Problem that method OnItemClickListener which I defined in MainActivity is override method OnItemLongClickListener which I defined in FragmentActivty and the method OnItemLongClickListener doesn't work at all then I tried to define both methods in FragmentActivity but after that both methods don't work at all.
Is there any way to determine this problem?

In my way I deleted definition both Methods from FavoriteFragment and defined it in MainActivity:

listView.setAdapter(adapterAirlines);

// getting values from selected ListItem
String name = ((TextView) view.findViewById(R.id.name))
.getText().toString();
String phone = ((TextView) view.findViewById(R.id.phone))
.getText().toString();
String site = ((TextView) view.findViewById(R.id.site))
.getText().toString();
String logoURL = String.valueOf(((ImageView) view.findViewById(R.id.logoURL)));
// Starting single contact activity
Intent in = new Intent(getApplicationContext(),
SingleContactActivity.class);
in.putExtra(TAG_NAME, name);
in.putExtra(TAG_PHONE, phone);
in.putExtra(TAG_SITE, site);
in.putExtra(TAG_LOGO, logoURL);
startActivity(in);
}
});
listView.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener() {
#Override
public boolean onItemLongClick(AdapterView<?> parent, View view,
int position, long id) {
ImageView button = (ImageView) view.findViewById(R.id.favorite_button);
String tag = button.getTag().toString();
if (tag.equalsIgnoreCase("grey")) {
sharedPreference.addFavorite(MainActivity.this, airlinesList.get(position));
Toast.makeText(MainActivity.this,
MainActivity.this.getResources().getString(R.string.add_favr),
Toast.LENGTH_SHORT).show();
button.setTag("red");
button.setImageResource(R.drawable.heart_red);
} else {
sharedPreference.removeFavorite(MainActivity.this, airlinesList.get(position));
button.setTag("grey");
button.setImageResource(R.drawable.heart_grey);

}
return true;
}
});
now it works

Android: item list click on JSON generated list view - unable to click

I am getting a JSON from a url to generate a list view of contact names & numbers. I intend to make it where users can just tap on the contact name or phone to make a call directly.

Thanks in advance.
SOLUTION FOUND:
add this into onCreate method
list = (ListView) findViewById(R.id.listView1);
list.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
Log.e("item clicks", "selected: " + position);
String item = list.getItemAtPosition(position).toString();
String contactNum = ((TextView)view.findViewById(R.id.listPhone)).getText().toString();
Log.e("phone number", contactNum);
Intent intent = new Intent(Intent.ACTION_CALL);
intent.setData(Uri.parse("tel:" + contactNum));
startActivity(intent);
}
});
thanks to Kunu for the help

Use this on your onCreate()
list.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> arg0, View view, int position,
long id) {
Log.e("item clicks", "selected: " + position);
String contactNum = ((TextView)view.findViewById(R.id.listPhone)).getText().toString();
phoneCall(contactNum);
}
});
and don't forget to import import android.widget.AdapterView.OnItemClickListener;
After retrieving the number try this to make a call
public void phoneCall(String number)
{
String phoneCallUri = "tel:"+number;
Intent phoneCallIntent =new Intent(Intent.ACTION_CALL);
phoneCallIntent.setData(Uri.parse(phoneCallUri));
startActivity(phoneCallIntent);
}

to set the itemClickListener use :
listView.setOnItemClickListener(ActivityName.this);
Override the method, and also inside the xml
set the focusableInTouchMode to false, and also focusable to false for the textviews
Hope that helps

in OnCreate list.setOnItemClickListener(new OnItemClickListener() {});and then Add unimplement method
public class MainActivity extends Activity {
ListView lView ;
String[] ara={"a","b","c","d","e","f"};
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
lView=(ListView)findViewById(R.id.listView1);
ListAdapter adapter = new ArrayAdapter(this,android.R.layout.simple_list_item_1,ara);
lView.setAdapter(adapter);
lView.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
// TODO Auto-generated method stub
}});
}
}

Webview is blank or loading same page for different urls

A search api is returning me some meta data i.e a url "eventURL" and trackbackurl i.e "trackBack". I am placing the data in the listview, each row containing some data and a unique url and trackback url.When user taps on the row in the listview, a alert dialog is displayed presenting user 2 options. Clicking on option 1 should launch trackback url in a webview while clicking on second opion should launch eventURL in a webview.I have created a WebViewActivity for it,Problem is that my webview is always blank.

WebViewActivity
package my.stayactive.plan;
import android.os.Bundle;
import android.view.KeyEvent;
import android.webkit.WebSettings;
import android.webkit.WebView;
import android.webkit.WebViewClient;
public class WebViewActivity extends StayActiveActivity {
private WebView webView;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.webview);
webView = (WebView) findViewById(R.id.webView);
WebSettings setting = webView.getSettings();
setting.setJavaScriptEnabled(true);
if (url != null && url.length()>0) {
webView.loadUrl(url);
}
}
}

You didn't pass URL to your WebViewActivity. To do that:
Before calling startActivity(), attach your URL to the intent with setData().
In onCreate() of WebViewActivity, retrieve the URL with getData(), then load it.
Or search for putExtra(...). You can transfer a number of data with Intent.
— edited —
Example:
To set data:
import android.net.Uri;
//...
Intent intent = new Intent (StayActiveActivity.this, WebViewActivity.class);
intent.setData(Uri.parse("your-url"));
StayActiveActivity.this.startActivity(intent);
To retrieve data:
//...
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//...
Uri uri = getIntent().getData();
//...
webView.loadUrl(uri.toString());
}

My guess is that your URLs are redirecting and that you aren't handling the redirects so nothing is being shown.
try adding this to your webview activity:
mWebView.setWebViewClient(new WebViewClient() {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url)
{
view.loadUrl(url);
return false;
}
});
Also it would be a good idea since you have an if statement in your WebView activity to log the url so that you can be certain that it is actually making it in to the activity correctly. If not the web view would never load anything.
EDIT: actually upon closer look it doesn't seem like you're setting the 'url' variable anywhere so it would be null, thus not calling your loadUrl method because of the if statement.

Thanks to jimpanzer and sherif-elkhatib, I have combined your comments to find the answer. The Answer is Changing: String className = mActivitiesIds[position]+".class"; to this: String className = "com.verscreative.BowlTrack."+mActivitiesIds[position];
