如何在PreferenceActivity中添加ToolBar？

Question

我想在Android應用程序中的PreferenceActivity中添加ToolBar 。 我寫了以下代碼。

  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();
        }
    });

}

這在我的機器人Kitkat手機API 19中完美運行，但強制關閉API級別10即姜餅 。 請建議我。

你需要一個包含Toolbar的布局，以及一個帶有android:id="@android:id/list"的ListView

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;
    }
    ...
}

• activity_settings.xml
• SettingsActivity.java

來自Android團隊的參考： AppCompatPreferenceActivity

Answer 2

嘗試：

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"?>
<android.support.design.widget.AppBarLayout
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:theme="@style/AppTheme.AppBarOverlay">

    <android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="?attr/actionBarSize"
        android:background="?attr/colorPrimary"
        app:popupTheme="@style/AppTheme.PopupOverlay"/>

</android.support.design.widget.AppBarLayout>

Answer 3

您可以從@android:style/Theme.Material.Light.DarkActionBar輕松添加工具欄

在AndroidManifest.xml中 ：

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

在v21 / styles.xml中

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

在v14 / styles.xml中，用於Back API支持

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

Answer 4

在我的情況下通過膨脹自定義工具欄非常容易和運作良好。 在你的java代碼中做如下，

   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();
        }

    }

在您的xml端代碼中，在頂部添加一個首選項類別，如下所示，

  <?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>

並在您的布局資源文件夾toolbar_setting中，

   <?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" />

Answer 5

我遲到了，但這是對問題的一個小修復，而不是編寫大量的代碼或添加龐大的庫。

轉到AndroidManifest.xml並在Preference Activity中添加自定義theme

 <activity
        android:name=".Dashboard.PreferencepActivity"
        android:label="@string/title_activity_preference"
        android:theme="@style/Pref"></activity>

這是上面添加到@style/Pref的自定義主題

 <style name="Pref" parent="Theme.AppCompat.DayNight.DarkActionBar">
    <!-- Customize your theme here. -->
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
</style>

希望能幫助到你！

Answer 6

代替：

public class PreferencesActivity extends Activity

做這個：

public class PreferencesActivity extends AppCompatActivity

Answer 7

此方法不會解決添加工具欄的問題，但您可以為設置頁面返回默認的ActionBar 。 通過從父主題繼承，為設置活動創建主題。

<style name="AppTheme" parent="Theme.MaterialComponents.Light.DarkActionBar.Bridge">
    <!-- Customize your theme here. -->
    <item name="windowNoTitle">true</item>
    <item name="windowActionBar">false</item>
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
</style>

<style name="AppTheme.Settings" parent="AppTheme">
    <item name="windowNoTitle">false</item>
    <item name="windowActionBar">true</item>
</style>

在AndroidManifest.xml中設置android:theme

<activity
    android:name=".Settings"
    android:theme="@style/AppTheme.Settings" />

就這些。
