Custom EditTextPreference doesn't show EditText area

Question

I have settings Activity with list of preferences from R.xml.preferences. One of the preferences here looks like this:

        <AuthPreference
        android:title="@string/auth_title"
        android:summary="@string/auth_summary"
        android:key="pass"
        android:defaultValue="1"
        android:dialogMessage="Provide a message"
        android:layout="@layout/preference_auth"/>

This preference extends EditTextPreference class so I expected this to show EditText area after the preference is clicked. But there is just empty dialog with no and yes buttons only. The code is shown below:

public class AuthPreference extends EditTextPreference {

    private ImageView icon;
    private EditText et;


public AuthPreference(Context context, AttributeSet attrs, int defStyle) {
    super(context, attrs, defStyle);
    setNegativeButtonText("no");
    setPositiveButtonText("yes");
}

public AuthPreference(Context context, AttributeSet attrs) {
    this(context, attrs, 0);
    setNegativeButtonText("no");
    setPositiveButtonText("yes");
}

@Override
protected void onBindView(View view) {
    super.onBindView(view);
    icon = (ImageView) view.findViewById(R.id.iconSelected);
}

@Override
    protected void onBindDialogView(View view) {


        some code
    }

}

What's wrong?

Answer 1

It turned out the second constructor was wrong because of passing the third arg to the immediate parent by super that was set to 0. So after changes I have

super(context, attrs);

instead of

super(context, attrs, 0);

You just need to be careful and make sure you pass corresponding args to specific parent's constructor.
