How can I use findViewById() in a Broadcast Receiver class. Below is my
code snippet. I get the error message: "can't resolve method findViewById"
if used directly without class constructor (because find View by Id is
Activity method and cant be used in Broadcast Receiver i suppose) . And if
i try to use the class constructor (Where the imageView is available in my
main activity) my app crashes saying " Unfortunately app has stopped" .
I just want to change the color of ImageView e.g "from black to blue" in
the below if statement if it is possible by any other means pleas let me
know.
This is my Broadcast Receiver class
public class MyBroadcastReceiver extends FirstBroadcastReceiver {
Context context;Activity activity;public MyBroadcastReceiver(Context context,
Activity activity){
this.context=context;
this.activity=activity;}
@Override
protected void (Context context) {
// content
}
@Override
public void onButton(Context context, boolean isClick) {
if(isClick) {
ImageView blueImage = (ImageView) activity.findViewById(R.id.imageView);
blueImage.setColorFilter(0xff000000);
}
}...........
// and so on
And this is my Main Activity
public class MainActivity extends AppCompatActivity {
@Overrideprotected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// and so on
}}
MyBroadcastReceiver myBroadcastReceiver = new
MyBroadcastReceiver(MainActivity.this,this);
@Override
public void onActivityResult() {
// some code
}
@Override
public void onInitialized(MyManager manager){
// some code
}
