仿QQ等的酷炫的视频背景登录页或者引导页

看到QQ的登录页比较酷炫，于是自己在网上学习着，做了个类似的，实际上很简单。接下来附上代码吧，一遍以后自己要用到。

1.在res目录下建个目录raw,该目录下把视频放进去。

2.新建个Java 类：

package com.pactera.madp.videobc.views;

import android.content.Context;import android.media.MediaPlayer;import android.util.AttributeSet;import android.view.KeyEvent;import android.widget.VideoView;

/** * Created by Monica on 2017/11/29. */

public class CustomVideoView extends VideoView {

public CustomVideoView(Context context) {        super(context);    }

public CustomVideoView(Context context, AttributeSet attrs) {        super(context, attrs);    }

public CustomVideoView(Context context, AttributeSet attrs, int defStyleAttr) {        super(context, attrs, defStyleAttr);    }

@Override    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {        //我们重新计算高度        int width = getDefaultSize(0, widthMeasureSpec);        int height = getDefaultSize(0, heightMeasureSpec);        setMeasuredDimension(width, height);    }

@Override    public void setOnPreparedListener(MediaPlayer.OnPreparedListener l) {        super.setOnPreparedListener(l);    }

@Override    public boolean onKeyDown(int keyCode, KeyEvent event) {        return super.onKeyDown(keyCode, event);    }}

3.接下来是Activity文件：

package com.pactera.madp.videobc;

import android.media.MediaPlayer;import android.net.Uri;import android.os.Bundle;import android.support.v7.app.AppCompatActivity;import android.view.View;import android.widget.Button;import android.widget.Toast;

import com.pactera.madp.videobc.views.CustomVideoView;

public class MainActivity extends AppCompatActivity implements View.OnClickListener{

private CustomVideoView videoview;    private Button btn_start;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);

initView();    }

/**     * 初始化     */    private void initView() {        btn_start = (Button) findViewById(R.id.btn_start);        btn_start.setOnClickListener(this);

videoview = (CustomVideoView) findViewById(R.id.videoview);        //设置播放加载路径        videoview.setVideoURI(Uri.parse("android.resource://"+getPackageName()+"/"+R.raw.guide_1));        //播放        videoview.start();        //循环播放        videoview.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {            @Override            public void onCompletion(MediaPlayer mediaPlayer) {                videoview.start();            }        });

}

@Override    public void onClick(View view) {        switch (view.getId()){            case R.id.btn_start:                Toast.makeText(this,"进入了主页",Toast.LENGTH_SHORT).show();                break;        }    }}

就是这么简单。4。xml文件如下：

<?xml version="1.0" encoding="utf-8"?><RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="match_parent"    tools:context="com.pactera.madp.videobc.MainActivity">

<com.pactera.madp.videobc.views.CustomVideoView            android:id="@+id/videoview"            android:layout_width="match_parent"            android:layout_height="match_parent" />

<Button            android:id="@+id/btn_start"            android:layout_width="100dp"            android:layout_height="wrap_content"            android:layout_alignParentBottom="true"            android:layout_centerHorizontal="true"            android:layout_marginBottom="56dp"            android:text="进入" />    </RelativeLayout>

5.就这样就完成了哦。
