Custom preference, targetSdkVersion=“11”: missing indent?

Question

I have a couple of custom DialogPreference implementations floating around, such as this one:

package apt.tutorial;

import android.content.Cont

You can dance with void Preference.setWidgetLayoutResource(int widgetLayoutResId) method, although I prefer to override View Preference.onCreateView(ViewGroup parent) method in my custom Preference class and hack it by adding custom views just below @android:id/summary (use hierarchyviewer utility for details).

The complete method is:

@Override
protected View onCreateView(ViewGroup parent)
{
    View ret = super.onCreateView(parent);

    View summary = ret.findViewById(android.R.id.summary);
    if (summary != null)
    {
        ViewParent summaryParent = summary.getParent();
        if (summaryParent instanceof ViewGroup)
        {
            final LayoutInflater layoutInflater = (LayoutInflater) getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            ViewGroup summaryParent2 = (ViewGroup) summaryParent;
            layoutInflater.inflate(R.layout.seek_bar_preference, summaryParent2);

            seekBar = (SeekBar) summaryParent2.findViewById(R.id.seekBar);
            seekBar.setMax(maxValue - minValue);
            seekBar.setOnSeekBarChangeListener(this);

            statusText = (TextView) summaryParent2.findViewById(R.id.seekBarPrefValue);

            unitsRightView = (TextView) summaryParent2.findViewById(R.id.seekBarPrefUnitsRight);
            unitsLeftView = (TextView) summaryParent2.findViewById(R.id.seekBarPrefUnitsLeft);
        }
    }

    return ret;
}
