Как добавить ToolBar в PreferenceActivity?

Question

Я хочу добавить ToolBar в PreferenceActivity в мое приложение для Android. Я написал следующий код.

public class SettingsActivity extends PreferenceActivity { 
SendSMS sms; 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    addPreferencesFromResource(R.xml.settings); 
    LinearLayout root = (LinearLayout)findViewById(android.R.id.list).getParent().getParent().getParent(); 
    android.support.v7.widget.Toolbar bar = (android.support.v7.widget.Toolbar) LayoutInflater.from(this).inflate(R.layout.action_bar_setting, root, false); 
    root.addView(bar, 0); 
    bar.setNavigationOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View v) { 
      onBackPressed(); 
     } 
    }); 

}

Это прекрасно работал в моем андроида Kitkat телефона API 19, но сила замкнута в уровне API 10, т.е. пряники. Пожалуйста, предложите мне.

Вам нужен макет, содержащий Toolbar и ListView с android:id="@android:id/list"

activity_settings.xml

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:id="@id/content_frame" 
    android:orientation="vertical" android:layout_width="match_parent" 
    android:layout_height="match_parent"> 
    <android.support.v7.widget.Toolbar 
     android:id="@id/toolbar" 
     android:layout_height="wrap_content" 
     android:layout_width="match_parent" 
     android:minHeight="?attr/actionBarSize" 
     android:background="?attr/colorPrimary" /> 
    <ListView 
     android:id="@android:id/list" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" /> 
</LinearLayout> 

SettingsActivity.java

public class SettingsActivity extends PreferenceActivity { 

    private AppCompatDelegate mDelegate; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     getDelegate().installViewFactory(); 
     getDelegate().onCreate(savedInstanceState); 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_settings); 
     setSupportActionBar((Toolbar) findViewById(R.id.toolbar)); 
     addPreferencesFromResource(R.xml.preferences); 
     ... 
    } 

    @Override 
    protected void onPostCreate(Bundle savedInstanceState) { 
     super.onPostCreate(savedInstanceState); 
     getDelegate().onPostCreate(savedInstanceState); 
    } 

    @Override 
    public void setContentView(@LayoutRes int layoutResID) { 
     getDelegate().setContentView(layoutResID); 
    } 

    @Override 
    protected void onPostResume() { 
     super.onPostResume(); 
     getDelegate().onPostResume(); 
    } 

    @Override 
    protected void onStop() { 
     super.onStop(); 
     getDelegate().onStop(); 
    } 

    @Override 
    protected void onDestroy() { 
     super.onDestroy(); 
     getDelegate().onDestroy(); 
    } 

    private void setSupportActionBar(@Nullable Toolbar toolbar) { 
     getDelegate().setSupportActionBar(toolbar); 
    } 

    private AppCompatDelegate getDelegate() { 
     if (mDelegate == null) { 
      mDelegate = AppCompatDelegate.create(this, null); 
     } 
     return mDelegate; 
    } 
    ... 
}

Try:

public class SettingsActivity extends AppCompatPreferenceActivity { 
..... 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setupActionBar(); 
    /* getFragmentManager().beginTransaction() 
      .replace(android.R.id.content, new GeneralPreferenceFragment()) 
      .commit(); 
    */ 

    //addPreferencesFromResource(R.xml.pref_general);   
} 

private void setupActionBar() { 
    ViewGroup rootView = (ViewGroup)findViewById(R.id.action_bar_root); //id from appcompat 

    if (rootView != null) { 
     View view = getLayoutInflater().inflate(R.layout.app_bar_layout, rootView, false); 
     rootView.addView(view, 0); 

     Toolbar toolbar = (Toolbar)findViewById(R.id.toolbar); 
     setSupportActionBar(toolbar); 
    } 

    ActionBar actionBar = getSupportActionBar(); 
    if (actionBar != null) { 
     // Show the Up button in the action bar. 
     actionBar.setDisplayHomeAsUpEnabled(true); 
    } 
} 

app_bar_layout.xml

<?xml version="1.0" encoding="utf-8"?>

Answer 4

Вы можете легко добавить панель инструментов @android:style/Theme.Material.Light.DarkActionBar

В AndroidManifest.xml:

<activity 
    android:name=".activity.SettingsActivity" 
    android:theme="@style/SettingsTheme" 
    android:label="Settings"/> 

В V21/styles.xml

<style name="SettingsTheme" parent="@android:style/Theme.Material.Light.DarkActionBar"> 
<item name="android:colorPrimary">@color/colorPrimary</item> 
<item name="android:colorPrimaryDark">@color/colorPrimaryDark</item> 

В V14/стили ,XML для поддержки спины API

<style name="SettingsTheme" parent="@android:style/Theme.Holo.Light.DarkActionBar"> 
<item name="android:actionBarStyle">@style/ActionBar.V14.Movie.NoTitle</item> 

Answer 5

Вместо:

public class PreferencesActivity extends Activity 

ли это:

public class PreferencesActivity extends AppCompatActivity 

Answer 6

Очень легко и хорошо работает в моем случае, раздувая пользовательскую панель инструментов. В вашем Java коде сделать, как показано ниже,

public class SettingsPrefActivity extends AppCompatPreferenceActivity { 
     // private static final String TAG = SettingsPrefActivity.class.getSimpleName(); 

     @Override 
     protected void onCreate(Bundle savedInstanceState) { 
      super.onCreate(savedInstanceState); 

      //setting up toolbar 
      getLayoutInflater().inflate(R.layout.toolbar_setting, (ViewGroup) findViewById(android.R.id.content)); 
      Toolbar toolbar = findViewById(R.id.toolbar); 
      toolbar.setTitle("Settings"); 
      setSupportActionBars(toolbar); 
      getSupportActionBar().setDisplayHomeAsUpEnabled(true); 

      // load settings fragment 
      getFragmentManager().beginTransaction().replace(android.R.id.content, new MainPreferenceFragment()).commit(); 
     } 

    } 

и в вашем XML-кода на стороне, добавьте одну категорию предпочтения в верхней сделать, как показано ниже,

<?xml version="1.0" encoding="utf-8"?> 
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:app="http://schemas.android.com/apk/res-auto"> 
//put below line at the top of your xml preference layout screen.. 
    <PreferenceCategory android:layout="@layout/toolbar_setting"></PreferenceCategory> 

и в макете папку ресурсов toolbar_setting,

<?xml version="1.0" encoding="utf-8"?> 
<android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:local="http://schemas.android.com/apk/res-auto" 
    xmlns:tools="http://schemas.android.com/tools" 
    android:id="@+id/toolbar" 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:background="?attr/colorPrimary" 
    android:elevation="@dimen/appbar_elevation" 
    android:minHeight="?attr/actionBarSize" 
    android:popupTheme="@style/ThemeOverlay.AppCompat.Light" 
    android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar" />
