I have a layout which contains some views. I want to set some actions when a user clicks anywhere in the layout, so I have set an OnClickListener for the layout which works clear. But how can I know which view was clicked? I want to assign different actions depends on the view which was clicked; or maybe no view was clicked and it was only the layout itself. So the problem is if I set OnClickListener for one of the views, both OnCLickListeners related to the layout and the view will get activated, but I want only the view action.Thanks in advance.
Other answers are quite abstract and some are incorrect. You can't Override onClick method for an Activity as it doesn't have one (unless of course you implement an OnClickListener).
Furthermore, if you set the listener for the layout the View
argument received by the onClick method will always be the layout.
You can either create your own custom layout that intercepts the clicks and check if you clicked on a view, or you can set listeners for all the views.
A somewhat cleaner solution is using a single listener and checking if it's a view that was clicked.
private final String TAG = "MainActivity";
List<View> views = new ArrayList<View>();
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
RelativeLayout rLayout = (RelativeLayout) findViewById(R.id.relativeLayout);
TextView tv1 = (TextView) findViewById(R.id.tv1);
TextView tv2 = (TextView) findViewById(R.id.tv2);
TextView tv3 = (TextView) findViewById(R.id.tv3);
views.add(tv1);
views.add(tv2);
views.add(tv3);
View.OnClickListener clickListener = new View.OnClickListener() {
@Override
public void onClick(View v) {
boolean isView = false;
for (View view : views) {
if (v.equals(view)) {
isView = true;
break;
}
}
if (isView) {
Log.e(TAG, "Click on view");
} else {
Log.e(TAG, "Click on layout");
}
}
};
tv1.setOnClickListener(clickListener);
tv2.setOnClickListener(clickListener);
tv3.setOnClickListener(clickListener);
rLayout.setOnClickListener(clickListener);
}
If you want different actions for different views, just create a listener for each of them.
