我有以下代码创建一个包含 EditText 的 PopupWindow:

lbs.setOnTouchListener(new OnTouchListener(){

        @Override
        public boolean onTouch(View v, MotionEvent arg1) {
            int pWidth = 100;
            int pHeight = 80;
            int vHeight = mView.getHeight();
            int[] location = new int[2];
            v.getLocationOnScreen(location);
            final View view = inflater.inflate(R.layout.list_popup, null, false);
            final PopupWindow pw = new PopupWindow(view, pWidth, pHeight, false);
            pw.setTouchable(true);
            //pw.setFocusable(true);
            pw.setOutsideTouchable(true);
            pw.setBackgroundDrawable(new BitmapDrawable());
            pw.setContentView(view);
            pw.showAtLocation(v, Gravity.NO_GRAVITY, location[0]-(pWidth/4), location[1]+vHeight);
            //final LinearLayout layout = (LinearLayout)view.findViewById(R.id.PopupLayout);

            final EditText input = (EditText)view.findViewById(R.id.Input);
            input.setOnFocusChangeListener(new View.OnFocusChangeListener() {

                @Override
                public void onFocusChange(View v, boolean hasFocus) {
                    Log.i("Focus", "Focus Changed");
                    /*
                    if (hasFocus) {
                        InputMethodManager inputMgr = (InputMethodManager)myContext.getSystemService(Context.INPUT_METHOD_SERVICE);
                        inputMgr.toggleSoftInput(InputMethodManager.SHOW_FORCED, 0);
                        inputMgr.showSoftInput(v, InputMethodManager.SHOW_IMPLICIT);
                    }
                    */

                }
            });
            input.setText(lbs.getText().toString());
            input.requestFocus();
            pw.setOnDismissListener(new OnDismissListener(){

                @Override
                public void onDismiss() {
                    parentActivity.changeWeight(getId, Double.parseDouble(input.getText().toString()));
                    Log.i("View Visibility", "" + view.getVisibility());
                }

            });

            pw.setTouchInterceptor(new View.OnTouchListener() {
                @Override
                public boolean onTouch(View v, MotionEvent event) {
                    if (event.getAction() == MotionEvent.ACTION_OUTSIDE) {
                        Log.i("Background", "Back Touched");
                        pw.dismiss();               
                        return true;
                    }
                    return false;
                }
            });

            return true;
        }   
    });

PopupWindows 有一个 setBackGroundDrawable ,因此当用户在窗口外触摸时,该框应自动关闭。我知道该框正在关闭,因为当我在框外单击时我的 OnDismiss 方法会运行,但实际窗口不会消失,直到我在框外触摸两次,因此 onDismiss 运行两次,这是我无法拥有的。我在这里想念什么?

编辑:我稍微更新了我的代码。如果我没有将焦点放在弹出窗口上,那么一切都会完美,除了我无法专注于我的编辑文本。如果我在弹出窗口上执行 setFocusable,则 edittext 不会立即获得焦点,我必须双击以将其删除。

我认为您可能会打开多个弹出窗口。onTouch 方法至少会在 touch down 和 touch up 时被调用,并且可能还有几个 touch 移动。尝试检查 (arg1.getAction() == MotionEvent.ACTION_UP) 并仅显示窗口。

您的弹出窗口没有获得父活动的上下文。尝试像这样而不是“final PopupWindow pw = new PopupWindow(view, pWidth, pHeight, false);”

final PopupWindow pw = new PopupWindow(getApplicationContext());
pw.setContentView(view);
pw.setHeight(pHeight);
pw.setWidth(pWidth);
pw.setFocusable(false);
