準備作業：
1.需要提前上傳一段音視頻 我這里是隨便找的音視頻
在res下新建一個目錄放置音視頻檔案，（將事先準備好的復制粘貼到該目錄就可以了）
界面布局
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout 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.example.myapplication.MainActivity">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="視頻播放器"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintHorizontal_bias="0.467"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintVertical_bias="0.032" />
<VideoView
android:id="@+id/videoView"
android:layout_width="399dp"
android:layout_height="341dp"
android:layout_marginBottom="8dp"
android:layout_marginEnd="8dp"
android:layout_marginStart="8dp"
android:layout_marginTop="8dp"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintVertical_bias="0.298" />
</android.support.constraint.ConstraintLayout>
代碼設計
package com.example.myapplication;
import android.graphics.PixelFormat;
import android.net.Uri;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.widget.MediaController;
import android.widget.VideoView;
public class MainActivity extends AppCompatActivity {
private VideoView videoView;
private MediaController mediaController;
private Uri uri;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
videoView=(VideoView)findViewById(R.id.videoView);
mediaController=new MediaController(this);
uri=Uri.parse("android.resource://"+ getPackageName()+ "/"+ R.raw.hetangyuese);
getWindow().setFormat(PixelFormat.TRANSLUCENT);
videoView.setVideoURI(uri);
videoView.setMediaController(mediaController);
videoView.requestFocus();
}
}
運行結果
