dialogActivity窗口化后避免点击区域外消失的办法

如果API Level>11

方法一：

<style name="Theme.SoundRecorder" parent="@android:style/Theme.Holo.DialogWhenLarge">          <item name="android:windowCloseOnTouchOutside">false</item>      </style>    

方法二：

Activity.this.setFinishOnTouchOutside(false); 

如果API Level<11

@Override      public boolean onTouchEvent(MotionEvent event) {          if (event.getAction() == MotionEvent.ACTION_DOWN && isOutOfBounds(this, event)) {              return true;          }          return super.onTouchEvent(event);      }      private boolean isOutOfBounds(Activity context, MotionEvent event) {          final int x = (int) event.getX();          final int y = (int) event.getY();          final int slop = ViewConfiguration.get(context).getScaledWindowTouchSlop();          final View decorView = context.getWindow().getDecorView();          return (x < -slop) || (y < -slop)|| (x > (decorView.getWidth() + slop))|| (y > (decorView.getHeight() + slop));      }
