Hi there,
I'm am trying to learn how to create LayoutGroups. For a start, I
created MyLinearLayout which is supposed to force all children into
same width (yes, there is layout_weight, but that's beside the
point :-)
However, the children won't show up. What am I missing here?
public class MyLinearLayout extends LinearLayout {
public MyLinearLayout(Context context) {
super(context);
}
public MyLinearLayout(Context context, AttributeSet attrs) {
super(context, attrs);
}
private final static int PADDING = 2;
@Override
protected void onLayout( boolean changed, int l, int t, int r, int
b ) {
//super.onLayout( changed, l, t, r, b );
//if( !changed ) return;
int len = getChildCount();
int w = ((r-l)-(len-1)*PADDING)/len;
int pos = l;
for( int i=0; i<len; i++ ) {
View c = getChildAt(i);
c.layout( pos, t, pos+w, b );
pos += w + PADDING;
}
}
@Override
protected void onMeasure( int wSpec, int hSpec ) {
int ws = MeasureSpec.getMode( wSpec );
int w = MeasureSpec.getSize(wSpec);
int hs = MeasureSpec.getMode( hSpec );
int h = MeasureSpec.getSize(hSpec);
setMeasuredDimension(wSpec,hSpec);
int len = getChildCount();
int w1 = (w-(len-1)*PADDING)/len;
for( int i=0; i<len; i++ ) {
View c = getChildAt(i);
c.measure(
MeasureSpec.makeMeasureSpec(w1,ws),
MeasureSpec.makeMeasureSpec(h, hs)
);
}
//super.onMeasure( wSpec, hSpec );
}
}
