如何设置可绘制对象的大小？

Question

The android developer docs say that the size for an icon in the action bar should be 32x32 dp . I have an xml as follows:

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:id="@+id/new_game"
          android:icon="@drawable/my_pic1"
          android:title="@string/new_game"
          android:showAsAction="ifRoom"/>
</menu>

How can I make the size of my_pic1 32x32dp?

Answer 1

you don't need to specify explicit size here, you just need to put correct drawable image in correct folder. You can download launcher icons from Here and put drawables according to their resolution in respective folders.
