navigation.menu
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:apps="http://schemas.android.com/tools">
<item
android:id="#+id/action_refresh"
android:icon="#drawable/noti"
app:showAsAction="always"
android:actionLayout="#layout/custom_action_notification_layout"
android:title="Refresh"/>
<item
android:id="#+id/action_task"
android:orderInCategory="100"
android:actionLayout="#layout/custom_action_task_layout"
android:title="Task"
android:icon="#drawable/task"
app:showAsAction="always" /></menu>
Now in my navigationdrawer.class i put thiscode onCreateOptionsMenu(), get ActionView of Notification and Task items and Set OnClick listeners to those ActionView.
navigation.class
#Override
public boolean onCreateOptionsMenu(final Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.navigation, menu);
// Notification
final MenuItem itemNotification = menu.findItem(R.id.action_refresh);
MenuItemCompat.setActionView(itemNotification, R.layout.custom_action_notification_layout);
View actionViewNotification = MenuItemCompat.getActionView(itemNotification);
// RelativeLayout notifCount = (RelativeLayout) MenuItemCompat.getActionView(itemNotification);
actionViewNotification.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
onOptionsItemSelected(itemNotification);
}
});
final MenuItem itemNotification1 = menu.findItem(R.id.action_task);
MenuItemCompat.setActionView(itemNotification1, R.layout.custom_action_task_layout);
View actionViewNotification1 = MenuItemCompat.getActionView(itemNotification1);
// RelativeLayout notifCount1 = (RelativeLayout) MenuItemCompat.getActionView(itemNotification1);
actionViewNotification1.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
onOptionsItemSelected(itemNotification1);
}
});
Now finally in onOptionsItemSelected() the code is like
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.action_refresh: {
// Do something
Toast toast = Toast.makeText(this, "Notification clicked", Toast.LENGTH_LONG);
toast.setGravity(Gravity.CENTER, 0, 0);
toast.show();
return true;
}
case R.id.action_task: {
// Do something
Toast toast = Toast.makeText(this, "Task clicked", Toast.LENGTH_SHORT);
toast.setGravity(Gravity.CENTER, 0, 0);
toast.show();
return true;
}
}
Tried in many ways but not working at all please help out from this..

1. Create two custom layout, one for Notification custom item and another for Task custom item.
custom_action_notification_layout.xml
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout
style="?attr/actionButtonStyle"
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:clipToPadding="false"
android:focusable="true">
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:src="#drawable/icon_notification"/>
<TextView
android:id="#+id/cart_badge"
android:layout_width="20dp"
android:layout_height="20dp"
android:layout_gravity="right|end|top"
android:layout_marginEnd="-5dp"
android:layout_marginRight="-5dp"
android:layout_marginTop="3dp"
android:background="#drawable/badge_background"
android:gravity="center"
android:padding="3dp"
android:textColor="#android:color/white"
android:text="0"
android:textSize="10sp"/>
</FrameLayout>
custom_action_task_layout.xml
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout
style="?attr/actionButtonStyle"
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:clipToPadding="false"
android:focusable="true">
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:src="#drawable/icon_task"/>
<TextView
android:id="#+id/cart_badge"
android:layout_width="20dp"
android:layout_height="20dp"
android:layout_gravity="right|end|top"
android:layout_marginEnd="-5dp"
android:layout_marginRight="-5dp"
android:layout_marginTop="3dp"
android:background="#drawable/badge_background"
android:gravity="center"
android:padding="3dp"
android:textColor="#android:color/white"
android:text="0"
android:textSize="10sp"/>
</FrameLayout>
2. Create a menu XML containing Notification and Task item. Use attribute app:actionLayout to set custom layout to each item.
custom_menu.xml
<menu
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto" >
<item
android:id="#+id/action_notification"
android:icon="#drawable/icon_notification"
android:title="Notification"
app:actionLayout="#layout/custom_action_notification_layout"
app:showAsAction="always"/>
<item
android:id="#+id/action_task"
android:icon="#drawable/icon_task"
android:title="Task"
app:actionLayout="#layout/custom_action_task_layout"
app:showAsAction="always"/>
</menu>
3. In your Activity onCreateOptionsMenu(), get ActionView of Notification and Task items and Set OnClick listeners to those ActionView.
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.custom_menu, menu);
// Notification
final MenuItem itemNotification = menu.findItem(R.id.action_notification);
View actionViewNotification = MenuItemCompat.getActionView(itemNotification);
actionViewNotification.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
onOptionsItemSelected(itemNotification);
}
});
// Task
final MenuItem itemTask = menu.findItem(R.id.action_task);
View actionViewTask = MenuItemCompat.getActionView(itemTask);
actionViewTask.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
onOptionsItemSelected(itemTask);
}
});
return true;
}
4. Finally, In onOptionsItemSelected() do the rest:
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.action_notification: {
// Do something
Toast toast = Toast.makeText(this, "Notification clicked", Toast.LENGTH_SHORT);
toast.setGravity(Gravity.CENTER, 0, 0);
toast.show();
return true;
}
case R.id.action_task: {
// Do something
Toast toast = Toast.makeText(this, "Task clicked", Toast.LENGTH_SHORT);
toast.setGravity(Gravity.CENTER, 0, 0);
toast.show();
return true;
}
}
return super.onOptionsItemSelected(item);
}
FYI, I have checked Notification and Task menu item click event by showing Toast messages.
OUTPUT:
UPDATE:
In your updated code use:
MenuItemCompat.setActionView(itemNotification, R.layout.custom_action_notification_layout);
View actionViewNotification = MenuItemCompat.getActionView(itemNotification);
Instead of
View actionViewNotification = MenuItemCompat.getActionView(itemNotification);
MenuItemCompat.setActionView(itemNotification, R.layout.custom_action_notification_layout);
Hope this will help~

I tried everything I knew, not I have no idea how to do it.
Thank you for attention!

The following will check which radio button is checked inside RadioGroup:
RadioGroup radioGroup = mView.findViewById(R.id.themeGroup);
radioGroup.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(RadioGroup radioGroup, int i) {
switch(i) {
case R.id.radioLight:
setLightTheme();
Toast.makeText(getApplicationContext(),"Light mode",Toast.LENGTH_LONG).show();
break;
case R.id.radioDark:
setDarkTheme();
Toast.makeText(getApplicationContext(),"Dark mode",Toast.LENGTH_LONG).show();
break;
}
}
});

I found some points in your code.
for first, I think you have to find your radio buttons from your view too.
like this:
RadioButton radioLight = mView.findViewById(R.id.radioLight);
final RadioButton radioDark = mView.findViewById(R.id.radioDark);
RadioButton radioSystem = mView.findViewById(R.id.radioSystem);
And for the second I think you can use SharedPreferences to find what the user has checked, before calling dialog.dimiss.

That's what was I trying to achieve
Boolean night = false;
public void chooseTheme(MenuItem item) {
final AlertDialog.Builder alert = new AlertDialog.Builder(MainActivity.this);
final View mView = getLayoutInflater().inflate(R.layout.dialog_theme,null);
Button btn_okay = mView.findViewById(R.id.btn_okay);
Button btn_cancel = mView.findViewById(R.id.btn_cancel);
alert.setView(mView);
final AlertDialog alertDialog = alert.create();
alertDialog.setCanceledOnTouchOutside(false);
final RadioGroup themeGroup = mView.findViewById(R.id.themeGroup);
themeGroup.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
#SuppressLint("NonConstantResourceId")
#Override
public void onCheckedChanged(RadioGroup themeGroup, int i) {
switch(i) {
case R.id.radioLight:
night = false;
break;
case R.id.radioDark:
night = true;
break;
}
}
});
btn_okay.setOnClickListener(new View.OnClickListener() {
#SuppressLint("SetTextI18n")
#Override
public void onClick(View v) {
if(night){
sharedpref.setNightModeState(true);
Toast.makeText(getApplicationContext(),"Dark mode", Toast.LENGTH_LONG).show();
}
else if (!night){
sharedpref.setNightModeState(false);
Toast.makeText(getApplicationContext(),"Light mode",Toast.LENGTH_LONG).show();
}
alertDialog.dismiss();
restartApp();
}
});
btn_cancel.setOnClickListener(new View.OnClickListener() {
#SuppressLint("SetTextI18n")
#Override
public void onClick(View v) {
alertDialog.dismiss();
}
});
alertDialog.show();
}
SharedPref:
public class SharedPref {
SharedPreferences mySharedPref ;
public SharedPref(Context context) {
mySharedPref = context.getSharedPreferences("filename",Context.MODE_PRIVATE);
}
// this method will save the nightMode State : True or False
public void setNightModeState(Boolean state) {
SharedPreferences.Editor editor = mySharedPref.edit();
editor.putBoolean("NightMode",state);
editor.apply();
}
// this method will load the Night Mode State
public Boolean loadNightModeState (){
Boolean state = mySharedPref.getBoolean("NightMode",false);
return state;
}

"I would like to have list_item's responding to click events and showing toast message..
Please Help..
THanks in Advance !!"

It may be because you are trying to perform click inside item click listener of ListView.
You can fix it by creating a custom adapter for listview. Customer ListView Adapter
After creating this custom adapter you can get the reference of description and loveBtn and perform click operation on this.
Your adapter's getView() code will be like this-
#Override
public View getView(int position, View convertView, ViewGroup parent) {
if(convertView==null) {
LayoutInflater layoutInflater = LayoutInflater.from(context);
convertView=layoutInflater.inflate(R.layout.list_row, null);
TextView description=convertView.findViewById(R.id.eventDesc);
Button loveBtn=convertView.findViewById(R.id.loveButton);
}
description.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (!TextUtils.isEmpty(mEventUrl)) {
Intent openLinkInBrowser = new Intent(Intent.ACTION_VIEW);
openLinkInBrowser.setData(Uri.parse(mEventUrl));
startActivity(openLinkInBrowser);
} else {
Toast.makeText(MainActivity.this, "Links are not provided", Toast.LENGTH_SHORT).show();
}
}
});
loveBtn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (status) {
Toast.makeText(MainActivity.this, "Liked", Toast.LENGTH_SHORT).show();
mEventsObject.setHeartLiked(true);
} else {
Toast.makeText(MainActivity.this, "Disliked", Toast.LENGTH_SHORT).show();
mEventsObject.setHeartLiked(false);
}
}
});
return convertView;
}

Android Popup Menu fill parent

I try set my popup menu in way to fill hole item on grid. Currently it look like on attached first picture and the next one is effect which I would like to have.
My code:
private void showPopupMenu(View view) {
// inflate menu
ContextThemeWrapper ctw = new ContextThemeWrapper(context, R.style.PopupMenu);
PopupMenu popup = new PopupMenu(ctw, view);
Menu menu = popup.getMenu();
menu.add(Menu.NONE, 1, Menu.NONE, "Remove");
menu.add(Menu.NONE, 2, Menu.NONE, "Block");
popup.setOnMenuItemClickListener(new MyMenuItemClickListener());
popup.show();
}
Could you please point me to right direction to achieve effect from project?

Demo App for your requirment by using PopupWindow. Preview
You can add list in it or customize it according to your needs.
MainActivity
public class MainActivity extends Activity {
boolean isClicked = true;
PopupWindow popUpWindow;
RelativeLayout relative;
ImageView btnClickHere;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
relative = (RelativeLayout) findViewById(R.id.relative);
popUpWindow = new PopupWindow(this);
popUpWindow.setContentView(getLayoutInflater().inflate(R.layout.popup_design, null));
popUpWindow.getContentView().findViewById(R.id.textViewa).setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Toast.makeText(MainActivity.this, "PopItemClicked", Toast.LENGTH_LONG).show();
}
});
btnClickHere = (ImageView) findViewById(R.id.imageView);
btnClickHere.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
if (isClicked) {
isClicked = false;
popUpWindow.setHeight(relative.getHeight());
popUpWindow.setWidth(relative.getWidth());
popUpWindow.showAsDropDown(relative, 0, -relative.getHeight());
} else {
isClicked = true;
popUpWindow.dismiss();

popup.getWindow().getAttributes().width = ViewGroup.LayoutParams.MATCH_PARENT;

Populate viewflipper from image from mysql database

I have a ViewFlipper populated with multiple ImageView. but now, i wanted to populate the view flipper with images from mysql database. But i don't know how to implement it.

java.lang.IllegalArgumentException: Target must not be null

When I am passing image url to Picasso then it shows me error "Target must not be null". When I fetch image from url using Picasso then it shows me error. Even my id assigned to image is correct. At last I replaced the image url with static image, though I receive error as same.
Here is my code:
public class MainScreen extends AppCompatActivity {
private ImageView user_profile_pic,img2;
private ImageView like_button,dislike_button,location_button,refresh;
private ArrayList<String> al;
private ArrayAdapter<String> arrayAdapter;
private int i;
private SwipeFlingAdapterView flingContainer;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main_screen);
//Setting
user_profile_pic=(ImageView)findViewById(R.id.profile_image);
img2=(ImageView)findViewById(R.id.img2);
//Picasso.with(getApplicationContext()).load("https://pbs.twimg.com/profile_images/596282530652753921/bPf8NmOs.jpg").into(user_profile_pic);
//Picasso.with(getApplicationContext()).load(android.R.drawable.btn_star).into(img);
Picasso.with(getApplicationContext()).load("https://pbs.twimg.com/profile_images/596282530652753921/bPf8NmOs.jpg")
.placeholder(android.R.drawable.btn_star)
.error(android.R.drawable.btn_star)
.into(img2);
flingContainer = (SwipeFlingAdapterView) findViewById(R.id.frame);
al = new ArrayList<>();
al.add("php");
al.add("c");
al.add("python");
al.add("java");
al.add("html");
al.add("c++");
al.add("css");
al.add("javascript");
arrayAdapter = new ArrayAdapter<>(this, R.layout.custom_user_details, R.id.helloText, al );
flingContainer.setAdapter(arrayAdapter);
flingContainer.setFlingListener(new SwipeFlingAdapterView.onFlingListener() {
#Override
public void removeFirstObjectInAdapter() {
Log.d("LIST", "removed object!");
al.remove(0);
arrayAdapter.notifyDataSetChanged();
}
#Override
public void onLeftCardExit(Object dataObject) {
Toast.makeText(getApplicationContext(),"Left !",Toast.LENGTH_SHORT).show();
}
#Override
public void onRightCardExit(Object dataObject) {
Toast.makeText(getApplicationContext(),"Right !",Toast.LENGTH_SHORT).show();
}
#Override
public void onAdapterAboutToEmpty(int itemsInAdapter) {
al.add("XML ".concat(String.valueOf(i)));
arrayAdapter.notifyDataSetChanged();
Log.d("LIST", "notified");
i++;
}
#Override
public void onScroll(float scrollProgressPercent) {
try
{
View view = flingContainer.getSelectedView();
view.findViewById(R.id.item_swipe_right_indicator).setAlpha(scrollProgressPercent < 0 ? -scrollProgressPercent : 0);
view.findViewById(R.id.item_swipe_left_indicator).setAlpha(scrollProgressPercent > 0 ? scrollProgressPercent : 0);
}
catch (NullPointerException e) {
Log.e("tag", "NullPointerException" + e);
}
}
});
//flingContainer.getTopCardListener().selectRight(); To remove view from right side while pressing button
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_main_screen, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}

img2 is null, and you're passing that into the into function.
Add a null check after img2=(ImageView)findViewById(R.id.img2); to check when it stops being null or whether it stays null while you're testing, or just to confirm that it is null.
Check your layout ID's and make sure they're right for ALL the configurations, and make sure you have #+id/img2 specified .

are you sure load the correct layout ? because you have R.id.profile_image in Java file, but i didn't found that id in your xml file.

You can't download image from https using Picasso library.
you can use this library.

try to change it as..
Picasso.with(MainScreen.this).load("https://pbs.twimg.com/profile_images/596282530652753921/bPf8NmOs.jpg")
.placeholder(android.R.drawable.btn_star)
.error(android.R.drawable.btn_star)
.into(img2);
also make sure that you are using the activity_main_screen.xml layout and check the id if img2 there.
