Loop through all childs of GroupView?

Question

Here is my code:

    Typeface font = Typeface.createFromAsset(getAssets(), \"fonts/choco.ttf\");  
    ViewGroup rootView = (ViewGroup) findViewById(android.         


        

Answer 1

You need to traverse View tree recursively. Currently you only list children of root view.

In other words, you need something like this:

@Override
public void onCreate(Bundle savedInstanceState) 
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    ...
    Typeface font = Typeface.createFromAsset(getAssets(), "fonts/choco.ttf");  
    ViewGroup rootView = (ViewGroup) findViewById(android.R.id.content).getRootView();
    applyFontRecursively(rootView, font);
}

void applyFontRecursively(ViewGroup parent, Typeface font) 
{    
    for(int i = 0; i < parent.getChildCount(); i++)
    {
        View child = parent.getChildAt(i);            
        if(child instanceof ViewGroup) 
        {
            applyFontRecursively((ViewGroup)child, font);
        }
        else if(child != null)
        {
            Log.d("menfis", child.toString());
            if(child.getClass() == TextView.class)
            {
                ((TextView) child).setTypeface(font);
            }
        }                
    }
}
