标签： android preferences inflate-exception preference-headers

我正在为我的应用程序的首选项部分使用首选项标头。他们工作得很好，但不知何故发生了什么事（我无法实现），我开始得到InflateException。相关的代码和日志显示在下面，任何人都可以得到我的代码有什么问题吗？

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：

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
        /*
         * Set back button
         */
    if (getActivity().getActionBar() != null) {
        getActivity().getActionBar().setDisplayHomeAsUpEnabled(true);
    }
    addPreferencesFromResource(R.xml.active_passive_app_prefs);
}

@Override
public void onResume() {
    super.onResume();
    registerListener();
}

@Override
public void onPause() {
    super.onPause();
    unregisterListener();
}

private void unregisterListener() {
    getPreferenceManager().getSharedPreferences()
            .unregisterOnSharedPreferenceChangeListener(this);
}
private void registerListener() {
    getPreferenceManager().getSharedPreferences()
            .registerOnSharedPreferenceChangeListener(this);
}

@Override
public void onSharedPreferenceChanged(SharedPreferences sharedPreferences,
                                      String key) {
    unregisterListener();
    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());
        } else {
            ActivityUtil.startService(sharedPreferences, getActivity(), resources);
        }
        TheBackupAgent.requestBackup(getActivity().getBaseContext());
    }
    registerListener();
}

GenderPrefs：

@Override

    super.onCreate(savedInstanceState);

}

@Override

    unregisterListener();
    Resources resources = getResources();
    if (key.equals(resources
            .getString(R.string.settings_gender_key))) {
        Gender[] genders = SuggestionData.getGenders(sharedPreferences, resources);
        SuggestionData.refreshSuggestionList(getResources().getAssets(), genders);
        setSummary();
        TheBackupAgent.requestBackup(getActivity().getBaseContext());
        SuggestionData.updateAppwidget(getActivity().getBaseContext());
    }
    registerListener();

private void setSummary() {
    ListPreference schedulePref = (ListPreference)findPreference(getResources().getString(R.string.settings_gender_key));
    SharedPreferences prefs = getPreferenceManager().getSharedPreferences();
    String selected = prefs.getString(getResources().getString(R.string.settings_gender_key), getResources().getString(R.string.settings_gender_defaultval));
    int index = schedulePref.findIndexOfValue(selected);
    String entry = (String) schedulePref.getEntries()[index];
    schedulePref.setSummary(getResources().getString(R.string.settings_gender_summary) + "\n[" + entry + "]");
}

SchedulePrefs：

            + "\n[" + prefs.getString(getResources()

当我单击首选项屏幕中的一个首选项标题时会发生这种情况。

另外，当我深入调试代码时，我遇到了这个：

在类LayoutInflater和方法createView中，代码在创建首选项布局场景时抛出异常。确切的部分是TextView（我没有手动将其放在首选项xml中），TextView的根本原因属性是layout_height。

谢谢。

答案 0 :(得分：0)

当我更改目标SDK版本时问题得到解决（我不记得我正在处理的版本我很抱歉，我写这篇文章是因为没有答案）。
