Android 横屏启动activity,点击屏幕的单击、双击和长按事件

横屏启动activity

方法1:在androidmanyfest.xml的activity中加入属性 android:screenOrientation="landscape"
方法2:首先添加
      import android.content.pm.ActivityInfo;
      import android.view.Display;
在oncreate中加入如下代码
if(getRequestedOrientation()!=ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE){ setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);}

  屏幕的单击和双击事件

  mGestureDetector = new GestureDetector(new SimpleOnGestureListener(){
 
  @Override
  public boolean onDoubleTap(MotionEvent e) {
  // TODO Auto-generated method stub
  return true;
  }
 
  @Override
  public boolean onSingleTapConfirmed(MotionEvent e) {
  // TODO Auto-generated method stub
  return true;
  }
 
  @Override
  public void onLongPress(MotionEvent e) {
  // TODO Auto-generated method stub
  }
