Android視頻剪輯

A. Android錄制視頻，需要對錄完的視頻進行自動處理。如何判斷視頻是否錄制完畢

先隨便設個用於回調的requestCode值，比如

publicstaticfinalintREQUEST_CODE_RECORD_FINISH=0;

然後調用系統自帶錄像機的代碼

Intentintent=newIntent();

intent.setAction(MediaStore.ACTION_VIDEO_CAPTURE);

intent.addCategory(Intent.CATEGORY_DEFAULT);

startActivityForResult(intent,REQUEST_CODE_RECORD_FINISH);

同時在同一Activity中實現回調方法

protectedvoidonActivityResult(intrequestCode,intresultCode,Intentdata){

if(requestCode==REQUEST_CODE_RECORD_FINISH&&resultCode==RESULT_OK){

Toast.makeText(getBaseContext(),"錄像完成，保存路徑："+data.getDataString(),Toast.LENGTH_LONG).show();

}

}

最後別忘了在Manifest文件里添加許可權

<uses-permissionandroid:name="android.permission.CAMERA"/>

<uses-permissionandroid:name="android.permission.RECORD_AUDIO"/>

<uses-permissionandroid:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

<uses-permissionandroid:name="android.permission.MOUNT_UNMOUNT_FILESYSTEMS"/>
