Activity代码：

public class PopupWindowTooltipTextActivity extends ActionBarActivity { private View contentView; private PopupWindow tipWindow; private Button anchor_view; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_popup_window_tooltip_text); anchor_view = (Button) findViewById(R.id.anchor_view); contentView = getLayoutInflater().inflate(R.layout.popup_window_tooltip_layout, null); tipWindow = new PopupWindow(this); tipWindow.setTouchInterceptor(new View.OnTouchListener() { @Override public boolean onTouch(View v, MotionEvent event) { if (event.getAction() == MotionEvent.ACTION_OUTSIDE) { tipWindow.dismiss(); } // 这个地方一定要返回false,你可能会说这里已经消费掉事件了啊应该返回true,参看PopupWindow的私有类PopupViewContainer // 弹出的View都是交由这个类来管理的，因为它对onTouchEvent()这个回调方法已经提供了一些默认实现,当你是返回true,事件就在此被拦截 // 不会再继续派发了,所以onTouchEvent()无法被调用 return false; } }); anchor_view.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { tipWindow.setWidth(ViewGroup.LayoutParams.WRAP_CONTENT); tipWindow.setHeight(ViewGroup.LayoutParams.WRAP_CONTENT); tipWindow.setOutsideTouchable(true); tipWindow.setTouchable(true); tipWindow.setFocusable(true); Bitmap bitmap = BitmapFactory.decodeResource(getResources(), R.drawable.easyicon_net); // 某些博客说，当没有设置Background的时候，无论是触摸其他空白区还是back键都无法dismiss()掉这个PopupWindow // 但我注释掉这段代码能dismiss(),有可能是个Bug,已经得google到修复 tipWindow.setBackgroundDrawable(new BitmapDrawable(getResources(),bitmap)); tipWindow.setContentView(contentView); // 计算这个PopupWindow的显示位置 int[] screen_pos = new int[2]; anchor_view.getLocationInWindow(screen_pos); Rect anchor_rect = new Rect(screen_pos[0], screen_pos[1], screen_pos[0] + anchor_view.getWidth(), screen_pos[1] + anchor_view.getHeight()); contentView.measure(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT); int contentViewWidth = contentView.getMeasuredWidth(); int contentViewHeight = contentView.getMeasuredHeight(); int position_x = anchor_rect.centerX() - (contentViewWidth / 2); int position_y = anchor_rect.bottom - (anchor_rect.height() / 2); tipWindow.showAtLocation(anchor_view, Gravity.NO_GRAVITY, position_x, position_y); } }); } }

还要注意一点就是：当你的已经dismiss()掉了，想再次显示PopupWindow，，那么它的某些属性需要重新设置，不能一处写好多处使用，参看这个dismiss()方法的源码实现。在没有dismiss()之前，你的PopupWindow内容发生变化了，你可以使用它的update()系列方法来更新.......
