android - PopupWindow 未按预期显示

Question

我正在尝试创建和显示PopupWindow：

private void setupPopupWindow() {
    TextView popTextView = new TextView(this);
    popTextView .setText("xxxxxxxxxxxxx");

    mPopupWindow = new PopupWindow(popTextView );
    mPopupWindow.setTouchable(true);
    mPopupWindow.setOutsideTouchable(true);
    mPopupWindow.showAtLocation(anotherViewInMyActivity, Gravity.CENTER, 120, 120);
}

但popupwindow不显示。

我错过了什么吗？

Answer 1

尝试为您的TextView.

setWidth(120);
setHeight(120);

如果弹出窗口会忽略外部触摸，只需设置背景

setBackgroundDrawable(new ColorDrawable(Color.WHITE));
