android - 无法单击 PopupWindow 中 Button 上的按钮

Question

当我显示一个包含 Button 的 PopupWindow 时，我无法点击他。执行 onclick，但不更改图形。

它显示弹出窗口:

public void btn_friendsgame_newClick(View v) {
    LayoutInflater layoutInflater = 
            (LayoutInflater)getBaseContext().getSystemService(LAYOUT_INFLATER_SERVICE);  

    View popupView = layoutInflater.inflate(R.layout.custom_dialog, null);

    RelativeLayout content = (RelativeLayout) popupView.findViewById(R.id.layout_content);



    Button b = new Button(this); // THIS BUTTON CAN'T CLICK!



    b.setText("Test");
    b.setLayoutParams(new LayoutParams(
            ViewGroup.LayoutParams.WRAP_CONTENT,
            ViewGroup.LayoutParams.WRAP_CONTENT));
    content.addView(b);

    final PopupWindow popupWindow = new PopupWindow(popupView, 
               LayoutParams.MATCH_PARENT,  LayoutParams.WRAP_CONTENT);  

    popupWindow.showAtLocation(this.findViewById(R.id.main), Gravity.CENTER, 0, 0);
    Button close = (Button) popupView.findViewById(R.id.btn_popup_settings);
    close.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View v) {
            popupWindow.dismiss();
        }
    });

如何修复？

Answer 1

您没有像使用关闭 按钮那样将他附加到onClickListener。我不知道你想要 b 做什么，所以我不能给你任何代码，但你显然知道如何将 onClick 事件附加到按钮，因为你已经有 close。对 b 做同样的事情，并将您需要的任何逻辑放入 onClick() 中，您应该能够点击他。

public void btn_friendsgame_newClick(View v) {
    LayoutInflater layoutInflater = 
            (LayoutInflater)getBaseContext().getSystemService(LAYOUT_INFLATER_SERVICE);  

    View popupView = layoutInflater.inflate(R.layout.custom_dialog, null);

    RelativeLayout content = (RelativeLayout) popupView.findViewById(R.id.layout_content);



    Button b = new Button(this); // THIS BUTTON CAN'T CLICK!



    b.setText("Test");
    b.setLayoutParams(new LayoutParams(
            ViewGroup.LayoutParams.WRAP_CONTENT,
            ViewGroup.LayoutParams.WRAP_CONTENT));
    content.addView(b);

   // here set onClick
   b.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View v) {
        // put logic in here to do whatever you want
      }


    final PopupWindow popupWindow = new PopupWindow(popupView, 
               LayoutParams.MATCH_PARENT,  LayoutParams.WRAP_CONTENT);  

    popupWindow.showAtLocation(this.findViewById(R.id.main), Gravity.CENTER, 0, 0);
    Button close = (Button) popupView.findViewById(R.id.btn_popup_settings);
    close.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View v) {
            popupWindow.dismiss();
        }
    });
