popupWindow通过按钮显示后,按下时消失,抬起时候又显示的问题

如果出现第一次点击Button会显示,再次点击就消失不了的问题(因为按下的时候popupWindo会先消失,但是抬起来又会显示)

(核心就是设置popupWindo的点击事件拦截监听,这里判断了是否点击到popupWindo的外面并且在指定的控件上面)

解决方案:直接来代码,

设置Pop点击事件拦截监听

public class MainActivity extends AppCompatActivity {
private MePopupWindow popupWindow;
private View btn;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
findViewById(R.id.btn).setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
showAndDismissPop();
}
});
}

/**
     * 显示pop/隐藏pop
     */
public void showAndDismissPop() {
//隐藏pop
if (popupWindow != null && popupWindow.isShowing()) {
popupWindow.dismiss();
return;
}
//显示pop
if (popupWindow == null) {//创建新的
createPopupWindow(popupWindow = new MePopupWindow(this));
} else if (!popupWindow.isShowing()) {//复用老的
popupWindow.showAsDropDown(btn);
}

}

/**
     * 创建新的窗体并显示
*/
public void createPopupWindow(MePopupWindow popupWindow) {
View root = View.inflate(this, R.layout.pop_filtrate, null);
popupWindow.setBackgroundDrawable(new BitmapDrawable());

4000
popupWindow.setOutsideTouchable(true);//这个是点击外部消失
popupWindow.setContentView(root);
setPopTouchInterceptor();
popupWindow.setWidth(FrameLayout.LayoutParams.MATCH_PARENT);
popupWindow.setHeight(FrameLayout.LayoutParams.WRAP_CONTENT);
popupWindow.showAsDropDown(btn);
}

/**
     * 设置Pop点击事件拦截监听
*/
public void setPopTouchInterceptor() {
popupWindow.setTouchInterceptor(new View.OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
popupWindow.dismiss();
//如果焦点不在popupWindow上
if (event.getAction() == MotionEvent.ACTION_OUTSIDE && !popupWindow.isFocusable()) {
//并且点击到了Button上面,那么返回true,不做dismiss的操作,反之返回false
return isInChangeImageZone(btn, (int) event.getRawX(), (int) event.getRawY());
}
return false;
}
});
}

private Rect mChangeImageBackgroundRect = null;

/**
     * 判断是否点击到了指定的控件上面
*/
private boolean isInChangeImageZone(View view, int x, int y) {
if (null == mChangeImageBackgroundRect) {
mChangeImageBackgroundRect = new Rect();
}
view.getDrawingRect(mChangeImageBackgroundRect);
int[] location = new int[2];
view.getLocationOnScreen(location);
mChangeImageBackgroundRect.left = location[0];
mChangeImageBackgroundRect.top = location[1];
mChangeImageBackgroundRect.right = mChangeImageBackgroundRect.right + location[0];
mChangeImageBackgroundRect.bottom = mChangeImageBackgroundRect.bottom + location[1];
return mChangeImageBackgroundRect.contains(x, y);
}
