在PopupWindow视图可以显示一个PopupMenu的？ [英] Can a View on a PopupWindow display a PopupMenu?

问题描述

在Android的API11 +我显示PopupWindow里面的按钮。我想表现出的PopupMenu单击该按钮时，无需关闭PopupWindow。这是可能的呢？
我实例化和initilizing的弹出菜单，但是当我打电话popupMenu.show（）
我得到这个错误（LogCat中+部分调用堆栈）：

In Android API11+ I'm displaying a button inside a PopupWindow. I'd like to show a PopupMenu when the button is clicked, without closing the PopupWindow. Is this possible at all? I'm instantiating and initilizing the PopupMenu, but when I call popupMenu.show() I'm getting this error (LogCat + partial call stack):

[rest of stack]

这是因为PopupMenu的使用另一个PopupWindow这似乎并没有被德从PopupWindow允许？同样的code运行正常，当我把它挂在活动内容视图按钮。

Is this because the PopupMenu uses another PopupWindow which does not seem te be allowed from a PopupWindow? Same code runs OK when I hook it up to a button in the Activity content view.

由于提前，

推荐答案

您不能从PopupWindow视图，你可以做的是从视图中roow此处查看或顶层的观点是一个定义或锚锚定的PopupMenu例如：

You can't anchor a PopupMenu from a PopupWindow view what you can do is define or anchor from a view inside roow view or top-level view here is an example:

main.xml中：

main.xml:

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context=".MainActivity" >


        <ImageView
            android:id="@+id/IVoptionsMenuInvis"
            android:layout_width="match_parent"
            android:layout_height="52dp"
            android:layout_gravity="center_horizontal"
            android:layout_weight="25"            
            android:paddingBottom="6dp"
            android:paddingTop="6dp">

</FrameLayout>

popupwindow.xml：

popupwindow.xml:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/settingseditback"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context=".MainActivity" >

<ImageView
            android:id="@+id/IVoptionsMenu"
            android:layout_width="match_parent"
            android:layout_height="52dp"
            android:layout_gravity="center_horizontal"
            android:layout_weight="25"
            android:onClick="showSettingsPopup2"
            android:paddingBottom="6dp"
            android:paddingTop="6dp"
            android:src="@drawable/ic_actionbar_overflow_dark" />

</LinearLayout>

和最后你的MainActivity.java：

and finally your MainActivity.java:

public class MainActivity extends Activity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.main);
    }
.
.
.
    public void showSettingsPopup2(View v) {
        PopupMenu popup = new PopupMenu(MainActivity.this, findViewById(R.id.IVoptionsMenuInvis));
        popup.setOnMenuItemClickListener(this);
        popup.getMenuInflater().inflate(R.menu.main, popup.getMenu());
        popup.show();
    }
}
