make fullScreenVideoView

我在android中創建自定義視頻播放器。我需要當設備處於肖像模式時，VideoView的高度是屏幕的一半，當我在橫向模式下旋轉設備時，它應該是全屏模式。但我不能沒有實現這一功能make fullScreenVideoView

下面

是我的XML代碼

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

，下面將我的活動代碼

public class MainActivity extends AppCompatActivity { 

    private int brightnessValue; 
    ContentResolver contentResolver; 
    Window window; 



    VideoView videoView; 
    private String url = "http://aklearningsolutions.com/video/Nursery Rhymes.mp4"; 
    SeekBar seekBar; 
    TextView maxTime,currentTime; 
    long totalDuration; 
    MediaPlayer mp; 
    Handler mHandler = new Handler(); 
    LinearLayout mediaController; 
    RelativeLayout frameLayout; 
    ImageView pause,fullScreenImage; 
    boolean isFullscreen; 
    LinearLayout otherView; 

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

     initialisedObject(); 
     playVideo(); 




    private void playVideo() { 

     Uri uri=Uri.parse(url.replace(" ","%20")); 
     videoView.setVideoURI(uri); 
     videoView.setOnPreparedListener(new MediaPlayer.OnPreparedListener() { 
      @Override 
      public void onPrepared(MediaPlayer mp) { 
       updateControllerWidget(mp); 
       videoView.start(); 


      } 
     }); 
    } 


    private void initialisedObject() { 
     seekBar = (SeekBar)findViewById(R.id.sick_bar); 
     maxTime = (TextView)findViewById(R.id.total_duration); 
     videoView = (VideoView)findViewById(R.id.videoView); 
     currentTime = (TextView)findViewById(R.id.time_current); 
     mediaController = (LinearLayout)findViewById(R.id.layout_controller); 
     frameLayout = (RelativeLayout) findViewById(R.id.video_frame); 
     pause = (ImageView)findViewById(R.id.pause); 
     fullScreenImage = (ImageView)findViewById(R.id.full_screenMode); 
     otherView = (LinearLayout)findViewById(R.id.other_view); 



    } 

    public void fullScreenVideo(){ 
     otherView.setVisibility(View.GONE); 
     frameLayout.setLayoutParams(new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.MATCH_PARENT,RelativeLayout.LayoutParams.MATCH_PARENT)); 
     fullScreenImage.setImageResource(R.drawable.ic_fullscreen_exit_white_24dp); 
     isFullscreen = true; 
     hideController(isFullscreen); 

    } 
    public void exitFullscreenVideo(){ 
     fullScreenImage.setImageResource(R.drawable.ic_fullscreen_white_24dp); 
     isFullscreen = false; 
     frameLayout.setLayoutParams(new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.MATCH_PARENT,RelativeLayout.LayoutParams.WRAP_CONTENT)); 

    } 



    @Override 
    public void onConfigurationChanged(Configuration newConfig) { 
     super.onConfigurationChanged(newConfig); 
     if(newConfig.orientation == Configuration.ORIENTATION_PORTRAIT){ 
      exitFullscreenVideo(); 
     }else if(newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE){ 
      fullScreenVideo(); 

     } 
    } 



}

use setRetainInstance（true）;在onCreate它會保持你的狀態時，方向變化 –

你提到的android：layout_height = 「@捫/ _200sdp」如此明顯它並沒有全屏顯示

創建layout-land文件夾並將下面的代碼放在相同的文件名和相同的編號下

<RelativeLayout 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" 
    android:orientation="vertical" > 

    <VideoView android:id="@+id/video" 
     android:layout_width="fill_parent" 
     android:layout_height="wrap_content" 
     android:layout_alignParentLeft="true" 
     android:layout_alignParentRight="true" 
     android:layout_alignParentBottom="true" 
     android:layout_alignParentTop="true" 
     /> 
</RelativeLayout>

，但我們需要在縱向模式下修復videoView 200的高度，爲了達到這個要求我修復了這個佈局的高度200 –

你應該在新的佈局layout-land directory再創建一個佈局，景觀視野

然後（景觀設計）

<RelativeLayout 
    android:layout_width="match_parent" 
    android:layout_height="match_parent"// change height to match_parent 
    android:orientation="vertical" > 

    <VideoView android:id="@+id/video" 
     android:layout_width="fill_parent" 
     android:layout_height="wrap_content" 
     android:layout_alignParentLeft="true" 
     android:layout_alignParentRight="true" 
     android:layout_alignParentBottom="true" 
     android:layout_alignParentTop="true" 
     /> 
</RelativeLayout>

如果你不想讓你的佈局重新創建時旋轉landcapse，你應該：
+通過onConfigurationChanged方法檢測取向變化
+檢查方向是縱向狀態>更改RelativeLayout = 200高度編程
+定向景觀 - >變化RelativeLayout = MATCH_PARENT

但我們需要將videoView 200的高度固定在肖像模式，爲了達到這個要求，我修正了這個佈局200的高度。如果我們使用match_parent，它在縱向模式下顯示全屏VideoView –

我創建了layout-land，但它不工作。爲了工作，我們從清單文件中移除了android：configChanges =「orientation | keyboardHidden | screenSize | layoutDirection」，結果是當我們旋轉屏幕視頻時將從開始播放。 –

@ shaileshojha請看我的更新答案。希望它可以給你一個想法來解決你的問題 –

據我瞭解你想要的佈局是在橫向模式全屏幕，如果是這樣

創建佈局，土地文件夾

橫向模式的新佈局隱藏ActionBar如果需要，然後進行VideoView match_parent高度和寬度佈局土地明智的。

類似的東西

<VideoView 
    android:id="@+id/video" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent"/>

UPDATE：這是不完美的，只是一個示例向您展示如何保存視頻的位置，然後繼續從那裏

private VideoView myVideoView; 
private int position = 0; 

//THEN OVERRIDE THESE TWO METHODS TO SAVE THE VIDEOVIEW Position BEFORE ACTIVITY GETS RECREATED 

@Override 
    public void onSaveInstanceState(Bundle savedInstanceState) { 
    super.onSaveInstanceState(savedInstanceState); 

    //HERE WE ARE SAVING VideoView SATATE 
    savedInstanceState.putInt("Position", myVideoView.getCurrentPosition()); 
    myVideoView.pause(); 
} 


@Override 
public void onRestoreInstanceState(Bundle savedInstanceState) { 
    super.onRestoreInstanceState(savedInstanceState); 

    //HERE WE GETTING THE Position BEFORE VIDEOVIEW WAS DESTROYED 
    position = savedInstanceState.getInt("Position"); 
    myVideoView.seekTo(position); 
}

我創建了layout-land，但它不起作用。爲了工作，我們從清單文件中移除了android：configChanges =「orientation | keyboardHidden | screenSize | layoutDirection」，結果是當我們旋轉屏幕視頻時將從開始播放。 –

實際情況是當你旋轉屏幕時活動被重新創建，所以你需要重寫'onSaveInstanceState'來保存視頻位置，找到了我？ – Max

你可以解釋更多的細節我們如何使用onSaveInstanceState來保存視頻位置 –

可能becozz你已經修復了你的相對佈局高度

<RelativeLayout 
     android:layout_alignParentTop="true" 
     android:layout_width="match_parent" 
==> android:layout_height="@dimen/_200sdp" <== here 
     android:id="@+id/video_frame">

使它變成match_parent和videoview wrap_content

，並在活動

   // full screen 
       getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, 
         WindowManager.LayoutParams.FLAG_FULLSCREEN);

添加此標誌，如果你想隱藏SystemUI底部導航欄，然後用這個。，

    // Set the IMMERSIVE flag. 
      // Set the content to appear under the system bars so that the content 
      // doesn't resize when the system bars hide and show. 
      int uiOptions = View.SYSTEM_UI_FLAG_HIDE_NAVIGATION 
        | View.SYSTEM_UI_FLAG_FULLSCREEN; 
      getWindow().getDecorView().setSystemUiVisibility(uiOptions);
