如何将数据从底表传递到Android中的片段？

Question

I am trying to pass values from a bottom sheet which contains some TextViews to a fragment. My fragment contains an EditText field and a Floating action button.When the user clicks on the floating action button, the bottom sheet shows up which has a number of TextViews, when the user clicks on any of the textViews on the bottom sheet, the value or the string of that TextView should be displayed in the editText field of the fragment and the bottom sheet should be dismissed.

I have tried implementing the onClickListener inside the setOnShowListener method but it doesn't seem to work.

Here is my code:

Fragment_TextPropert1_EditText.xml

As a simple solution you may use LocalBroadcastManager .

public static final String SOME_INTENT_FILTER_NAME = "SOME_INTENT_FILTER_NAME";

In your fragment:

private BroadcastReceiver someBroadcastReceiver = new BroadcastReceiver() {
    @Override
    public void onReceive(Context context, Intent intent) {
        //TODO extract extras from intent
    }
};
@Override
public void onResume() {
    super.onResume();
    LocalBroadcastManager.getInstance(getContext()).registerReceiver(someBroadcastReceiver,
            new IntentFilter(SOME_INTENT_FILTER_NAME));
}
@Override
public void onPause() {
    LocalBroadcastManager.getInstance(getContext()).unregisterReceiver(someBroadcastReceiver);
    super.onPause();
}

In your bottomsheet:

Intent someIntent = new Intent(SOME_INTENT_FILTER_NAME);
//TODO put extras to your intent
LocalBroadcastManager.getInstance(context).sendBroadcast(someIntent);
