YouTube 视频在 Android 中再次开始全屏缓冲

Question

我已将 YouTube 视频集成到我的 Android 应用中。现在的问题是当视频变成全屏（横向）模式时，它又开始缓冲了。如何解决这个问题？

下面是我用过的全部代码。

public class MainActivity extends YouTubeBaseActivity implements YouTubePlayer.OnInitializedListener {

    private static final int RECOVERY_DIALOG_REQUEST = 1;

    // YouTube player view
    private YouTubePlayerView youTubeView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        youTubeView = (YouTubePlayerView) findViewById(R.id.youtube_view);

        // Initializing video player with developer key
        youTubeView.initialize(Config.DEVELOPER_KEY, this);
    }

    @Override
    public void onInitializationFailure(YouTubePlayer.Provider provider,
                                        YouTubeInitializationResult errorReason) {
        if (errorReason.isUserRecoverableError()) {
            errorReason.getErrorDialog(this, RECOVERY_DIALOG_REQUEST).show();
        } else {
            Toast.makeText(this, "Error!", Toast.LENGTH_LONG).show();
        }
    }

    @Override
    public void onInitializationSuccess(YouTubePlayer.Provider provider, YouTubePlayer player, boolean wasRestored) {
        if (!wasRestored) {

            // loadVideo() will auto play video
            // Use cueVideo() method, if you don't want to play it automatically
            player.loadVideo(Config.YOUTUBE_VIDEO_CODE);

            // Hiding player controls
            //player.setPlayerStyle(YouTubePlayer.PlayerStyle.CHROMELESS);
        }
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        if (requestCode == RECOVERY_DIALOG_REQUEST) {
            // Retry initialization if user performed a recovery action
            getYouTubePlayerProvider().initialize(Config.DEVELOPER_KEY, this);
        }
    }

    private YouTubePlayer.Provider getYouTubePlayerProvider() {
        return (YouTubePlayerView) findViewById(R.id.youtube_view);
    }
}

第 1 步：将以下行添加到您的 AndroidMenifest 文件中：

<uses-permission android:name="android.permission.INTERNET"/>
<activity android:name=".MainActivity" android:configChanges="orientation|keyboardHidden|screenSize|screenLayout|uiMode|screenLayout|keyboard">

第二步：activity_main.xml 文件：

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity">

<com.google.android.youtube.player.YouTubePlayerView
    android:id="@+id/youtube5"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_centerHorizontal="true"
    android:layout_alignParentTop="true"/>

</RelativeLayout>

第 3 步：创建新类并命名为“Config”，您可以根据自己的意愿命名，该类必须如下所示，此“Config”类用于您的“YouTubeApi”键和“Video Id”

public class Config {
    public static final String YOUTUBEAPI_KEY = "AIzaSyC5lyioipD0SpJ0UJ5hxz-EDVnO1gZyeI4";
    public static final String YOUTUBE_VIDEO_ID = "fhWaJi1Hsfo";
}

MainActivity.java 文件如下：

package com.example.tulasi.youtube2;
import android.content.Intent;
import android.content.res.Configuration;
import android.os.Bundle;
import android.provider.Settings;
import android.view.WindowManager;
import android.widget.Toast;
import com.google.android.youtube.player.YouTubeBaseActivity;
import com.google.android.youtube.player.YouTubeInitializationResult;
import com.google.android.youtube.player.YouTubePlayer;
import com.google.android.youtube.player.YouTubePlayer.Provider;
import com.google.android.youtube.player.YouTubePlayerView;
public class MainActivity extends YouTubeBaseActivity implements YouTubePlayer.OnInitializedListener  {

    private static final int RECOVERY_REQUEST = 1;
    private YouTubePlayerView youTubeView;
    private boolean mAutoRotation = false;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        mAutoRotation = Settings.System.getInt(getContentResolver(),
                Settings.System.ACCELEROMETER_ROTATION, 0) == 1;
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
                WindowManager.LayoutParams.FLAG_FULLSCREEN);
        youTubeView = (YouTubePlayerView) findViewById(R.id.youtube5);
        youTubeView.initialize(Config.DEVELOPER_KEY, this);
    }

    @Override
    public void onInitializationSuccess(Provider provider, YouTubePlayer player, boolean wasRestored) {

        if(mAutoRotation) {
            player.addFullscreenControlFlag(YouTubePlayer.FULLSCREEN_FLAG_CONTROL_ORIENTATION
                    | YouTubePlayer.FULLSCREEN_FLAG_CONTROL_SYSTEM_UI
                    | YouTubePlayer.FULLSCREEN_FLAG_ALWAYS_FULLSCREEN_IN_LANDSCAPE
                    | YouTubePlayer.FULLSCREEN_FLAG_CUSTOM_LAYOUT);
        }else {
             player.addFullscreenControlFlag(YouTubePlayer.FULLSCREEN_FLAG_CONTROL_ORIENTATION
                     | YouTubePlayer.FULLSCREEN_FLAG_CONTROL_SYSTEM_UI
                     | YouTubePlayer.FULLSCREEN_FLAG_CUSTOM_LAYOUT);
        }
        if (!wasRestored) {
            player.loadVideo(Config.YOUTUBE_VIDEO_CODE);
        }
    }

    @Override
    public void onInitializationFailure(Provider provider, YouTubeInitializationResult errorReason) {
        if (errorReason.isUserRecoverableError()) {
            errorReason.getErrorDialog(this, RECOVERY_REQUEST).show();
        } else {
           // String error = String.format(getString(R.string.player_error), errorReason.toString());
            Toast.makeText(this, "error", Toast.LENGTH_LONG).show();
        }
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        if (requestCode == RECOVERY_REQUEST) {
            // Retry initialization if user performed a recovery action
            getYouTubePlayerProvider().initialize(Config.DEVELOPER_KEY, this);
        }
    }

    protected Provider getYouTubePlayerProvider() {
        return youTubeView;
    }

    @Override
    public void onConfigurationChanged(Configuration newConfig) {
        super.onConfigurationChanged(newConfig);
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
                WindowManager.LayoutParams.FLAG_FULLSCREEN);
    }

}

Answer 2

尝试将其添加到您的清单中

android:configChanges="orientation|keyboard|keyboardHidden|screenSize|screenLayout|uiMode"

在 oncreate 里面添加这个

getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
            WindowManager.LayoutParams.FLAG_FULLSCREEN);

在活动的任何地方添加

@Override
public void onConfigurationChanged(Configuration newConfig) {
    super.onConfigurationChanged(newConfig);
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
            WindowManager.LayoutParams.FLAG_FULLSCREEN);
}

希望这会奏效

Answer 3

<activity
  android:configChanges="keyboardHidden|orientation|screenSize"
  android:name="com.example.MainActivity">

把它放在你的清单中，引用你的主要活动。
