我只想实现与Gmail应用程序中弹出菜单相同的功能,并固定在右上角的溢出按钮上。为此,我使用了与Google教程相同的代码来编写android Android弹出菜单,但是对我来说,在操作栏边缘顶部显示弹出菜单,而不是在其下方。如果您在gmail溢出的弹出菜单上注意到,您会看到popmenu发生在操作栏的边缘。
这是我用于弹出菜单的xml:
<menu xmlns:android="http://schemas.android.com/apk/res/android" >
<item
android:id="@+id/item1"
android:title="lablab"/>
<item
android:id="@+id/item2"
android:title="lablab"/>
</menu>
以下是我的活动:
public void showFontSetting(View view) {
PopupMenu popup = new PopupMenu(this, view);
MenuInflater inflater = popup.getMenuInflater();
inflater.inflate(R.menu.menu, popup.getMenu());
popup.show();
popup.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {
@Override
public boolean onMenuItemClick(MenuItem item) {
// TODO Auto-generated method stub
switch (item.getItemId()) {
case R.id.item1:
Toast.makeText(Index.this,
"You Clicked : " + item.getTitle(),
Toast.LENGTH_SHORT).show();
break;
case R.id.item2:
break;
}
return true;
}
});
}
将以下代码段添加到您的活动中:
PopupWindow popupwindow_obj; // create object
popupwindow_obj=popupDisplay(); // initialize in onCreate()
popupwindow_obj.showAsDropDown(clickbtn,-40, 18); // where u want show on view click event
public PopupWindow popupDisplay() { // disply designing your popoup window
final PopupWindow popupWindow = new PopupWindow(this); // inflet your layout or diynamic add view
View view;
LayoutInflater inflater = (LayoutInflater) getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
view = inflater.inflate(R.layout.mylayout, null);
Button item = (LinearLayout) view.findViewById(R.id.button1);
popupWindow.setFocusable(true);
popupWindow.setWidth(WindowManager.LayoutParams.WRAP_CONTENT);
popupWindow.setHeight(WindowManager.LayoutParams.WRAP_CONTENT);
popupWindow.setContentView(view);
return popupWindow;
}
在res/layout
目录中创建XML并将其命名mylayout.xml
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<Button
android:id="@+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Window test" />
</LinearLayout>
