Got InflateException After Clicking On a Preference Header Inside PreferenceActivity

I am using preference headers for the preferences part of my application. They were working great but somehow something happened (that I couldn't realize) and I started to get InflateException. The related codes and logs are present below, can anyone get what is wrong with my code?

PreferenceActivity:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    /*
     * Set back button
     */
    if (getActionBar() != null) {
        getActionBar().setDisplayHomeAsUpEnabled(true);
    }
    /*
     * Set status bar color
     */
    ActivityUtil.setStatusBarColor(getWindow(), getResources());
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {
        case android.R.id.home:
            finish();
            return (true);
    }
    return false;
}

@Override
public void onBuildHeaders(List<Header> target) {
    loadHeadersFromResource(R.xml.preference_headers, target);
    setContentView(R.layout.preference);
}

@Override
protected boolean isValidFragment(String fragmentName) {
    return (ActivePassivePrefs.class.getName().equals(fragmentName)
            || SchedulePrefs.class.getName().equals(fragmentName)
            || GenderPrefs.class.getName().equals(fragmentName));
}

@Override
public void finish() {
    super.finish();
    overridePendingTransition(R.anim.slide_anim_righttoleft,
            R.anim.slide_anim_righttoleft_fromcenter);
}

ActivePassivePrefs:

    Resources resources = getResources();
    if (key.equals(resources
            .getString(R.string.settings_enabledisable_checkbox_key))) {
        boolean isAppEnabled = sharedPreferences.getBoolean(key, Constants.DEFAULT_IS_APP_ENABLED);
        if (!isAppEnabled) {
            ActivityUtil.stopService(getActivity());

This happens when I click one of the preference headers inside preference screen.

Also, when I debug the code deeply, I come across with this:

In the class LayoutInflater and method createView, the code throws exception when creating the preference layout scene. The exact part is a TextView (which I do not put it manually to the preference xml) and the root cause attribute of the TextView is layout_height.

Thanks with regards.

Solution

  • The problem was resolved when I changed my target SDK version (I do not remember the versions that I was working on I am sorry, I am writing this because got no answer).
