I wrote a custom view that extends RelativeLayout
. My view has text, so I want to use the standard android:text
without the need to specify a <declare-styleable>
and without using a custom namespace xmlns:xxx
every time I use my custom view.
this is the xml where I use my custom view:
<my.app.StatusBar
android:id="@+id/statusBar"
android:text="this is the title"/>
How can I get the attribute value? I think I can get the android:text attribute with
TypedArray a = context.obtainStyledAttributes(attrs, ???);
but what is ???
in this case (without a styleable in attr.xml)?
use this:
public YourView(Context context, AttributeSet attrs) {
super(context, attrs);
int[] set = {
android.R.attr.background, // idx 0
android.R.attr.text // idx 1
};
TypedArray a = context.obtainStyledAttributes(attrs, set);
Drawable d = a.getDrawable(0);
CharSequence t = a.getText(1);
Log.d(TAG, "attrs " + d + " " + t);
a.recycle();
}
i hope you got an idea
