本文介紹了android/286060.html">android 仿QQ動態背景、視頻背景的示例代碼,分享給大家,具體如下:
效果如下:
	
 
	
如上圖類似效果圖:
1, 自定義視頻類 繼承VideoView
 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 defStyle) {    super(context, attrs, defStyle);  }  @Override  protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {    //我們重新計算高度    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);  }}MainActivity 中:
public class MainActivity extends AppCompatActivity implements View.OnClickListener {    private CustomVideoView videoview;    private Button  btn_enter;    @Override    protected void onCreate(Bundle savedInstanceState) {      super.onCreate(savedInstanceState);      // requestWindowFeature(Window.FEATURE_NO_TITLE);      setContentView(R.layout.activity_main);      initView();    }    /**     * 初始化     */    private void initView() {      btn_enter = (Button) findViewById(R.id.btn_enter);      btn_enter.setOnClickListener(this);      videoview = (CustomVideoView) findViewById(R.id.videoview);      videoview.setVideoURI(Uri.parse("android.resource://"+getPackageName()+"/"+R.raw.shipin2));      //播放      videoview.start();      //循環播放      videoview.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {        @Override        public void onCompletion(MediaPlayer mediaPlayer) {          videoview.start();          mediaPlayer.setOnInfoListener(new MediaPlayer.OnInfoListener() {            @Override            public boolean onInfo(MediaPlayer mp, int what, int extra) {              return false;            }          });        }      });    }    @Override    public void onClick(View view) {      switch (view.getId()){        case R.id.btn_enter:          Toast.makeText(this,"登錄成功了",Toast.LENGTH_SHORT).show();          break;      }    }    //返回重啟加載    @Override    protected void onRestart() {      super.onRestart();      initView();    }    //防止鎖屏或者切出的時候,音樂在播放    @Override    protected void onStop() {      super.onStop();      videoview.stopPlayback();    }  }讀取視頻的問題: 把視頻放到和res/raw文件夾里面了

注意:
視頻資源要添加res文件夾下創建raw文件夾
需要在onRestart()方法里重新加載視頻,防止退出返回時視頻黑屏
