尝试调用此方法时，我收到以下异常。

}
}

将您的代码更改为：

private void showLocationPopup() {

    LayoutInflater inflater = (LayoutInflater)
            getActivity().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    View layout = inflater.inflate(R.layout.popup_location,(ViewGroup) getActivity().findViewById(R.id.layout_location_popup));
    PopupWindow pw = new PopupWindow(
            layout,
            100,
            100,
            true);
    // The code below assumes that the root container has an id called 'main'
    pw.setWindowLayoutMode(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT);
    pw.showAtLocation(layout, Gravity.CENTER, 0, 0);

}

和

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:padding="10dip"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#FFFFFF"
android:id="@+id/layout_location_popup">

<TextView
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:layout_marginTop="10dip"
    android:text="Test Pop-Up"/>
</LinearLayout>

我改变了颜色，因为你选择的颜色不起作用。对我来说似乎不是典型的安卓颜色。此外，我已将布局宽度和高度设置为＆＃39; WRAP_CONTENT＆＃39;。对我来说，它现在在屏幕中间以白色背景显示正常。
