仿QQ等的酷炫的視頻背景登陸頁或者引導頁

看到QQ的登陸頁比較酷炫，因而本身在網上學習着，作了個相似的，實際上很簡單。接下來附上代碼吧，一遍之後本身要用到。

1.在res目錄下建個目錄raw,該目錄下把視頻放進去。

2.新建個Java 類：

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) {
 //咱們從新計算高度
 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.接下來是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);
 //設置播放加載路徑
 videoview.setVideoURI(Uri.parse("android.resource://"+getPackageName()+"/"+R.raw.guide_1));
 //播放
 videoview.start();
 //循環播放
 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,"進入了主頁",Toast.LENGTH_SHORT).show();
 break;
 }
 }
}

就是這麼簡單。
4。xml文件以下：

<?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="進入" />
 </RelativeLayout>5.就這樣就完成了哦。
