Android开发使用VideoView播放视频

一、布局文件

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.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=".VideoViewActivity">
    <VideoView
        android:id="@+id/videoView"
        android:layout_width="match_parent"
        android:layout_height="match_parent"/>

    <Button
        android:id="@+id/btnStartPlayView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="开始"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent" />
</androidx.constraintlayout.widget.ConstraintLayout>

二、activity源码

package com.example.learning01;

import androidx.appcompat.app.AppCompatActivity;

import android.os.Bundle;
import android.text.TextUtils;
import android.util.Log;
import android.view.TextureView;
import android.view.View;
import android.widget.Button;
import android.widget.MediaController;
import android.widget.VideoView;

import java.io.File;

public class VideoViewActivity extends AppCompatActivity implements View.OnClickListener {

    private static final String TAG = "VideoViewActivity";

    private VideoView videoView;
    private Button btn;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_video_view);

        videoView= findViewById(R.id.videoView);
        btn = findViewById(R.id.btnStartPlayView);

        btn.setOnClickListener(this);

        //控制窗口
        MediaController mediaController = new MediaController(this);
        mediaController.setPrevNextListeners(this,this);
        videoView.setMediaController(mediaController);


        //开始播放视频
        videoView.setVideoPath(new File(getExternalFilesDir(""),"video.mp4").getAbsolutePath());
        videoView.start();
    }

    @Override
    public void onClick(View view) {
        Log.e(TAG, "onClick: ");
    }
}
