android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"

2.配置权限
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
3.功能实现
package demo.jq.com.playvideotest;
import android.content.pm.PackageManager;
import android.net.Uri;
import android.support.v4.app.ActivityCompat;
import android.support.v4.content.ContextCompat;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.Toast;
import android.widget.VideoView;

public class MainActivity extends AppCompatActivity implements View.OnClickListener{
private VideoView videoView;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
videoView = (VideoView) findViewById(R.id.video_view);
Button play = (Button) findViewById(R.id.play);
Button pause = (Button) findViewById(R.id.pause);
Button replay = (Button) findViewById(R.id.replay);
play.setOnClickListener(this);
pause.setOnClickListener(this);
replay.setOnClickListener(this);
if (ContextCompat.checkSelfPermission(MainActivity.this, android.Manifest.permission.WRITE_EXTERNAL_STORAGE)!= PackageManager.PERMISSION_GRANTED) {
ActivityCompat.requestPermissions(MainActivity.this,new String[]{android.Manifest.permission.WRITE_EXTERNAL_STORAGE},1);
} else {
initVideoPath();
}
}
private void initVideoPath() {
try {
Uri uri = Uri.parse("android.resource://demo.jq.com.playvideotest/"+R.raw.video);
videoView.setVideoURI(uri);
} catch (Exception e) {
e.printStackTrace();
}
}
@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
switch (requestCode) {
case 1:
if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
initVideoPath();
} else {
Toast.makeText(this,"拒绝权限将无法使用程序",Toast.LENGTH_SHORT).show();
finish();
}
break;
default:
}
}
@Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.play:
if (!videoView.isPlaying()) {
videoView.start();
}
break;
case R.id.pause:
if (videoView.isPlaying()) {
videoView.pause();
}
break;
case R.id.replay:
if (videoView.isPlaying()) {
videoView.seekTo(0);
videoView.resume();
}
break;
default:
break;
}
}
@Override
public void onDestroy() {
super.onDestroy();
if (videoView != null) {
videoView.suspend();
}
}
}
