如何將數據從底部表單傳遞到android中的片段？

我想從包含一些TextViews的底部工作表的值傳遞給一個片段。我的片段包含一個EditText字段和一個浮動操作按鈕。當用戶點擊浮動操作按鈕時，底部工作表顯示其中有多個TextView，當用戶單擊底部工作表上的任何textView時，值或該TextView的字符串應該顯示在片段的editText字段中，並且底部表單應該被解除。如何將數據從底部表單傳遞到android中的片段？

我已經嘗試在setOnShowListener方法內部實現onClickListener，但它似乎不工作。

這裏是我的代碼：

作爲一個簡單的解決方案，您可以使用LocalBroadcastManager。

public static final String SOME_INTENT_FILTER_NAME = "SOME_INTENT_FILTER_NAME";

在您的片段：

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(); 
}

在你bottomsheet：

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