android - 如何在 Activity 中传递 onActivityResult 数据？

Question

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == 900) {
        if (resultCode == getActivity().RESULT_OK) {
            Bundle b=data.getExtras();
            if(b!=null){
                Playlist playlist = (Playlist) b.getSerializable("obj");
                int playlistId = data.getIntExtra("PLAYLIST_ID", 0);

                Log.d("---->Data ID", String.valueOf(playlistId));
            }
        }
    }

如何在 onCreate() 方法中发送 playlistId 值？

Answer 1

结果 Activity :

  intent.putExtra("yourKeyName", "hello");
    setResult(900, intent);

获取结果:

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (resultCode== 900) {
        if (resultCode == getActivity().RESULT_OK) {
            String hello = data.getStringExtra("yourKeyName");  
        }
    }

您不必创建新的 Bundle，只需从“Intent 数据”中获取额外的内容即可。希望这会有所帮助。
