笔记如下
源代码实现:
layout中
<?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="com.chen.video_surfaceview.MainActivity">
<SurfaceView
android:id="@+id/vv"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
</RelativeLayout>
MainActivity中
package com.chen.video_surfaceview;
import android.Manifest;
import android.app.Activity;
import android.content.pm.PackageManager;
import android.media.MediaPlayer;
import android.os.Bundle;
import android.support.v4.app.ActivityCompat;
import android.support.v4.content.ContextCompat;
import android.view.SurfaceHolder;
import android.view.SurfaceView;
import android.widget.Toast;
public class MainActivity extends Activity {
private SurfaceView vv;
private MediaPlayer mPlayer;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
vv = (SurfaceView)findViewById(R.id.vv);
vv.getHolder().addCallback(new SurfaceHolder.Callback() {
@Override
public void surfaceCreated(SurfaceHolder holder) {
mPlayer = new MediaPlayer();
mPlayer.reset();
try {
mPlayer.setOnErrorListener(new MediaPlayer.OnErrorListener() {
@Override
public boolean onError(MediaPlayer mp, int what, int extra) {
return false;
}
});
mPlayer.setDataSource("storage/emulated/0/areyouok.3gp");
mPlayer.setDisplay(holder);
mPlayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
@Override
public void onPrepared(MediaPlayer mp) {
mPlayer.start();
}
});
mPlayer.prepare();
} catch (Exception e) {
e.printStackTrace();
}
}
@Override
public void surfaceChanged(SurfaceHolder holder, int format, int width, int height) {
}
@Override
public void surfaceDestroyed(SurfaceHolder holder) {
if (mPlayer != null){
mPlayer.stop();
mPlayer.release();

});
}
