Android 如何向AppCompativePreferenceActivity添加工具栏？

我正在尝试向中添加工具栏，但不知道如何添加

---

你能告诉我怎么做吗？

使用PreferenceFragment，你可以在活动中这样做：

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

getSupportFragmentManager().beginTransaction().replace(R.id.content_frame, new MyPreferenceFragment()).commit();

MyPreferenceFragment是这样的：

public class MyPreferenceFragment extends PreferenceFragment{
    @Override
    public void onCreate(final Bundle savedInstanceState){
        super.onCreate(savedInstanceState);
        addPreferencesFromResource(R.xml.settings);
    }
}

public class SettingsActivity extends AppCompatPreferenceActivity {

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

    private void setupActionBar() {
        Toolbar toolbar;

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.ICE_CREAM_SANDWICH) {
            ViewGroup root = (ViewGroup) findViewById(android.R.id.list).getParent().getParent().getParent();
            toolbar = (Toolbar) LayoutInflater.from(this).inflate(R.layout.view_toolbar, root, false);
            root.addView(toolbar, 0);
        } else {
            ViewGroup root = (ViewGroup) findViewById(android.R.id.content);
            ListView content = (ListView) root.getChildAt(0);
            root.removeAllViews();
            toolbar = (Toolbar) LayoutInflater.from(this).inflate(R.layout.view_toolbar, root, false);
            int height;
            TypedValue tv = new TypedValue();
            if (getTheme().resolveAttribute(R.attr.actionBarSize, tv, true)) {
                height = TypedValue.complexToDimensionPixelSize(tv.data, getResources().getDisplayMetrics());
            } else {
                height = toolbar.getHeight();
            }
            content.setPadding(0, height, 0, 0);
            root.addView(content);
            root.addView(toolbar);
        }
        setSupportActionBar(toolbar);
        getSupportActionBar().setDisplayHomeAsUpEnabled(true);
    }
}

希望这有帮助

试试这个：

public class SettingsActivity extends AppCompatPreferenceActivity {

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

        LinearLayout root = (LinearLayout) findViewById(android.R.id.list).getParent().getParent().getParent();
        Toolbar toolbar = (Toolbar) LayoutInflater.from(this).inflate(R.layout.toolbar_settings, root, false);
        root.addView(toolbar, 0);
        setSupportActionBar(toolbar);
        getSupportActionBar().setDisplayHomeAsUpEnabled(true);
    }
}

编辑

AppCompatPreferenceActivity是支持v7的此演示类：

第一次复制到您的项目中

用户可以这样使用它：

public class MyPreferenceFragment extends PreferenceFragment{

    public void onCreate(final Bundle savedInstanceState){
        super.onCreate(savedInstanceState);
        addPreferencesFromResource(R.xml.settings);
    }
}

public class SettingsActivity extends AppCompatPreferenceActivity {

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

这不是一个非常优雅的解决方案，但它很有效。在姜饼和棒棒糖上测试。

您可以使用Android Studio生成设置活动，它可以自动生成如下示例代码：

public class MyPreferenceFragment extends PreferenceFragment{
    @Override
    public void onCreate(final Bundle savedInstanceState){
        super.onCreate(savedInstanceState);
        addPreferencesFromResource(R.xml.settings);
    }
}

public class SettingsActivity extends AppCompatPreferenceActivity {

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

            int id = item.getItemId();
            if ( id == android.R.id.home ) {
                startActivity( new Intent( getActivity(), SettingsActivity.class ) );
                return true;
            }
            return super.onOptionsItemSelected( item );
        }
    }
}

仅供参考，pref_标题的用法由页面给出 并在onCreate（）方法中添加这一行

然后转到配置您的首选项XML（用法也在该页面上）。运行你的应用程序，你会发现它可以工作。然后你可以做一些其他的事情，比如装饰/在工具栏上添加菜单/添加监听器

或者只是添加一些与你的应用程序相关的逻辑代码。

我解决了在AndredManifest上将主题加入活动的问题

android:theme="@style/Theme.AppCompat.Light"

这是我的toolbar.xml

<?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:minHeight="?attr/actionBarSize"
android:background="?attr/colorPrimary"
android:elevation="@dimen/appbar_elevation"
android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
android:popupTheme="@style/ThemeOverlay.AppCompat.Light" />

这工作对我很好

谢谢

不，我不是指PreferenceFragment，我是指使用新AppCompatDelegate的AppCompatPreferenceActivity。您可以在这个链接中找到它：

PreferenceFragment

不在支持库中，因此您不能使用

SupportFragmentManager

。您应该使用

PreferenceFragmentCompat

如何在其中添加首选项？我不必使用任何

setupActionBar（）

代码，只需复制AppCompatPreferenceActivity，扩展了它，它工作了。是的，如果你有合适的应用主题，它似乎工作了。如果应用程序AppTheme扩展了某个主题。没有操作栏，则没有操作栏，必须从布局中添加操作栏。如果你想让这个新的自定义工具栏带有一个ActionBar，它可以工作。这看起来像是一个Android 2.x首选项活动。那么使用它有什么意义呢？
