android popupWindow伪菜单背景半透明以及触摸事件的相关问题

Question

popupWindow伪菜单popupWindow触摸事件menu菜单项

Answer 1

我先贴上源码 /**menu菜单选项*/
private void showPopupWindow() {
View view = (LinearLayout)getLayoutInflater()
.inflate(R.layout.activity_menu_prop, null);
LinearLayout scanmusic = (LinearLayout)view
.findViewById(R.id.menu_scanmusic);
LinearLayout equalizer = (LinearLayout)view
.findViewById(R.id.menu_equalizer);
LinearLayout sleep = (LinearLayout)view
.findViewById(R.id.menu_sleep);
LinearLayout preferences = (LinearLayout)view
.findViewById(R.id.menu_preferences);
LinearLayout exit = (LinearLayout)view
.findViewById(R.id.menu_exit);
LinearLayout menu_null = (LinearLayout)view
.findViewById(R.id.menu_null);
//设置选项size
int newW = dm_width-Utils.dip2px(this, 0.5f);
LinearLayout.LayoutParams param = 
new LinearLayout.LayoutParams(newW/3, (newW/3)/3*2);
scanmusic.setLayoutParams(param);
equalizer.setLayoutParams(param);
sleep.setLayoutParams(param); 
preferences.setLayoutParams(param);
exit.setLayoutParams(param);
menu_null.setLayoutParams(param);

scanmusic.setOnClickListener(new myOnClickListener());
equalizer.setOnClickListener(new myOnClickListener());
sleep.setOnClickListener(new myOnClickListener());
preferences.setOnClickListener(new myOnClickListener());
exit.setOnClickListener(new myOnClickListener());
popupWindow = new PopupWindow(WindowManager.LayoutParams.MATCH_PARENT,WindowManager.LayoutParams.WRAP_CONTENT);
popupWindow.setFocusable(true); //设置PopupWindow可获得焦点  
popupWindow.setTouchable(true); //设置PopupWindow可触摸
popupWindow.setOutsideTouchable(false); //设置非PopupWindow区域是否可触摸

popupWindow.setContentView(view);
backgroundAlpha(0.5f);
//添加pop窗口关闭事件  
popupWindow.setOnDismissListener(new poponDismissListener());
popupWindow.setAnimationStyle(R.style.popuStyle); //设置 popupWindow动画样式
popupWindow.showAtLocation(findViewById(R.id.main_layout), Gravity.BOTTOM, 0, 0);
}

Answer 2

为什么用 popwindow ？  不是有原生的menu吗？

Answer 3

原生的menu菜单都是一字竖着在底部中间排列的！

Answer 4

在onkeydown 或onkeyup事件的返回按键中加入隐藏的代码
if(popupWindow!=null&& popupWindow.isShow()){
popupWindow.dissmiss();
}

Answer 5

已经搞定了！
View view = (LinearLayout)getLayoutInflater().inflate(R.layout.activity_menu_prop, null);在这个xml布局里最外层（我这里是LinearLayout）加上如下代码：//下面部分代码主要用于响应按键事件（menu、back）
LinearLayout layout = (LinearLayout)view.findViewById(R.id.menu_layout);
layout.setFocusableInTouchMode(true);//能够获得焦点
layout.setOnKeyListener(new OnKeyListener() {

@Override
public boolean onKey(View v, int keyCode, KeyEvent event) {
if (event.getAction() == KeyEvent.ACTION_DOWN) {
                    switch(keyCode) {
                    case KeyEvent.KEYCODE_BACK:
                     closePopupWindow();
                        break;
                    case KeyEvent.KEYCODE_MENU:
                     closePopupWindow();
                        break;
                    }
                }
                return true;
}
});就OK了！非常完美！
完整代码如下： /**menu菜单选项*/
private void showPopupWindow() {
View view = (LinearLayout)getLayoutInflater()
.inflate(R.layout.activity_menu_prop, null);
LinearLayout scanmusic = (LinearLayout)view
.findViewById(R.id.menu_scanmusic);

LinearLayout menu_null = (LinearLayout)view
.findViewById(R.id.menu_null);
//设置选项size
int newW = dm_width-Utils.dip2px(this, 0.5f);

scanmusic.setLayoutParams(param);
equalizer.setLayoutParams(param);
sleep.setLayoutParams(param); 
preferences.setLayoutParams(param);
exit.setLayoutParams(param);
menu_null.setLayoutParams(param);

scanmusic.setOnClickListener(new myOnClickListener());
equalizer.setOnClickListener(new myOnClickListener());
sleep.setOnClickListener(new myOnClickListener());
preferences.setOnClickListener(new myOnClickListener());
exit.setOnClickListener(new myOnClickListener());
popupWindow = new PopupWindow(WindowManager.LayoutParams.MATCH_PARENT,WindowManager.LayoutParams.WRAP_CONTENT);
popupWindow.setContentView(view);
popupWindow.setFocusable(true); //设置PopupWindow可获得焦点(设置setFocusable属性，会无法响应按键事件，因此在下面加上setOnKeyListener)
popupWindow.setTouchable(true); //设置PopupWindow可触摸
popupWindow.setOutsideTouchable(false); //设置非PopupWindow区域是否可触摸
backgroundAlpha(0.4f);
//添加pop窗口关闭事件
popupWindow.setOnDismissListener(new poponDismissListener());
popupWindow.setAnimationStyle(R.style.popuStyle); //设置 popupWindow动画样式
popupWindow.showAtLocation(findViewById(R.id.main_layout), Gravity.BOTTOM, 0, 0);
//下面部分代码主要用于响应按键事件（menu、back）

                    case KeyEvent.KEYCODE_MENU:
                     closePopupWindow();
                        break;
                    }
                }
                return true;
}
});
} /**关闭popupWindow*/
private void closePopupWindow(){
if (popupWindow!=null) {
popupWindow.dismiss();
popupWindow=null;
}
}
