使用com.android.youtube.player.YouTubeSupportFGragment的另一个片段重复id，null或parent id

Question

当我尝试第二次显示Youtube播放器时，我收到以下错误。

 Caused by: java.lang.IllegalArgumentException: Binary XML file line #44: Duplicate id 0x7f070086, tag null, or parent id 0x7f070022 with another fragment for com.google.android.youtube.player.YouTubePlayerSupportFragment

MainActivity.java是

package com.example.sample;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import com.example.sample.VideoPlayerDialog;

public class MainActivity extends AppCompatActivity {

public static final String EXTRA_MESSAGE = "com.example.sample.MESSAGE";

private VideoPlayerDialog mVideoPlayerDialog;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
}

public void showYoutube(View view) {
    mVideoPlayerDialog = new VideoPlayerDialog(MainActivity.this);
    showVideoPlayer("");
}

private void showVideoPlayer(String videoUrl) {
    runOnUiThread(() -> {
        if (!videoUrl.isEmpty()) {
            mVideoPlayerDialog.playVideo(videoUrl);
        }
        if (!mVideoPlayerDialog.isShowing()) {
            mVideoPlayerDialog.show();
        }
    });
}}

任何人都可以告诉上面的代码有什么问题。很抱歉延迟回复，我没有获得发布整个代码的权限，因此创建了一个仅包含YouTube部分的示例应用。

您是否尝试使用Activity / Fragment中的dialog.dismiss（）更改dialog.cancel（）？

编辑：我想如果你使用DialogFragment，你的问题将解决你。

你应该使用getChildFragmentManager来嵌套片段。因为YoutubeFragment将在从DialogFragment扩展的片段中打开

FragmentTransaction transaction = getChildFragmentManager().beginTransaction();
transaction.add(R.id.youtube_fragment, youTubePlayerFragment).commit();
