표면 뷰 비디오 레코딩에서 각도를 변경하는 방법은 무엇입니까?

Question

미디어 레코더가있는 surfaceview을 사용하여 비디오를 녹화 중입니다. 녹음 중이지만 표시 각도가 90도 시프트되어 실제 실내 기록과 다릅니다. 즉, 내 앱으로 실내를 녹화하는 경우 디스플레이는 90 학위가 바뀌었고, 방 천장이 왼쪽에 있으므로 방이 나옵니다. 어느 누구도이 문제를 해결하여 직각 비디오로 녹화 할 수 있도록 도와줍니다. 여기 내 코드는

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:orientation="horizontal" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" 
    > 
<SurfaceView 
    android:id="@+id/videoview" 
    android:layout_height="480px" android:layout_width="248dp"/> 
<Button 
    android:id="@+id/mybutton" 
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:text="REC" 
    android:textSize="12dp"/> 
</RelativeLayout>`

행동의 방향을 매니페스트에서 가로 방향으로 변경하십시오.

<application android:icon="@drawable/icon" android:label="@string/app_name"> <activity android:name=".SurfaceAngleRecActivity" android:screenOrientation="landscape" android:label="@string/app_name"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> </application>

private void initMediaRecorder() 
      { 
       mediaRecorder.setAudioSource(MediaRecorder.AudioSource.DEFAULT); 
       mediaRecorder.setVideoSource(MediaRecorder.VideoSource.DEFAULT); 
       //File file=new File(Environment.getExternalStorageDirectory(), PlayPath); 
       CamcorderProfile camcorderProfile_HQ =CamcorderProfile.get(CamcorderProfile.QUALITY_HIGH); 
       mediaRecorder.setProfile(camcorderProfile_HQ); 
       mediaRecorder.setOutputFile("/sdcard/myvideo.mp4"); 
       **mediaRecorder.setOrientationHint(90);** 
      }
