将Activity设置成窗口的样式实现Dialog或者Popupwindow效果在开发中是很常用的一种方式,在AndroidMenifest.xml中将需要设置的Activity增加android:theme="@android:style/Theme.Dialog"属性即可。但是窗口化的Activity有个问题就是:点击窗口空白处Activity会finish。如何避免这个问题呢,办法如下:
一、如果API Level>=11有两种方式:
1、
res\values\styles.xml
<resources> <style name="Theme.SoundRecorder" parent="@android:style/Theme.Holo.DialogWhenLarge"> <item name="android:windowCloseOnTouchOutside">false</item> </style> </resources>
2,
YourActivity.this.setFinishOnTouchOutside(false);
二、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)); }
