Example 1
@Override
public boolean setViewValue(final View v, final Cursor c, final int columnIndex) {
    if (!IS_SHORTCUT_API_SUPPORTED) {
        // just let SimpleCursorAdapter set the view values
        return false;
    }
    if (columnIndex == INDEX_SHORTCUT) {
        final String shortcut = c.getString(INDEX_SHORTCUT);
        if (TextUtils.isEmpty(shortcut)) {
            v.setVisibility(View.GONE);
        } else {
            ((TextView)v).setText(shortcut);
            v.setVisibility(View.VISIBLE);
        }
        v.invalidate();
        return true;
    }

    return false;
}
 
Example 2
private void blueStreakOfProgress(Integer current, Integer max) {
	// Set up the progress bar
	if (mProgressWidth == 0) {
		final View vShareProgressEmpty = (View) findViewById(R.id.vShareProgressEmpty);
		mProgressWidth = vShareProgressEmpty.getMeasuredWidth();
	}
	// Display stuff
	if (max == 0)
		max = 1;
	int width = (int) ((float) mProgressWidth) * current / max;

	View vShareProgressFull = (View) findViewById(R.id.vShareProgressFull);
	vShareProgressFull.getLayoutParams().width = width;
	vShareProgressFull.invalidate();
	vShareProgressFull.requestLayout();
}
