Question

In a custom view I can get the custom attrs value from the AttributeSet (shown below). But how do I get the Android attributes? For instance, how do I access android:background or android:text ? android.R.styleable isn’t allowed.

<mine.custom.RangeSeekBar
    custom:selectedMinValue="2"
    custom:selectedMaxValue="4"
    android:background="@drawable/my_skin" />


public RangeSeekBar(Context context, AttributeSet attrs, int defStyle) {
TypedArray a = context.obtainStyledAttributes(attrs, R.styleable.RangeSeekBar, defStyle, 0);
    selectedMinValue = a.getInt(R.styleable.RangeSeekBar_selectedMinValue, selectedMinValue);
    selectedMaxValue = a.getInt(R.styleable.RangeSeekBar_selectedMaxValue, selectedMaxValue);
    minRangeValue = a.getInt(R.styleable.RangeSeekBar_minRangeValue, minRangeValue);
    maxRangeValue = a.getInt(R.styleable.RangeSeekBar_maxRangeValue, maxRangeValue);
    a.recycle();
}

Edit: Is this the standard way?

final String xmlns="http://schemas.android.com/apk/res/android";
    int xmlRes = attrs.getAttributeResourceValue(xmlns, "background", -1);
    String xmlText = attrs.getAttributeValue(xmlns, "text");

I guess we’ll go with this:

final String xmlns="http://schemas.android.com/apk/res/android";
int xmlRes = attrs.getAttributeResourceValue(xmlns, "background", -1);
String xmlText = attrs.getAttributeValue(xmlns, "text");
