首选项活动中添加工具栏
。我编写了以下代码
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();
}
});
}
这在我的androidKitkat手机API 19中运行得非常好,但在API级别10时强制关闭,即姜饼。请建议我。您需要一个包含工具栏
和列表视图
以及android:id=“@android:id/list”

Android团队的参考资料:试试:
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);
}
}

您可以从@android:style/Theme.Material.Light.darkaActionBar
在AndroidManifest.xml中:

android:theme="@style/SettingsTheme"
android:label="Settings"/>
在v21/styles.xml中

在v14/styles.xml中获取后台API支持

@style/ActionBar.V14.Movie.NoTitle
而不是:
public class PreferencesActivity extends Activity
这样做:
public class PreferencesActivity extends AppCompatActivity
非常简单,在我的情况下,通过膨胀自定义工具栏工作良好。
在java代码中,执行以下操作:
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();
}
}
<?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>
在xml端代码的顶部添加一个首选项类别,如下所示:
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();
}
}
<?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>
//将下一行放在xml首选项布局屏幕的顶部。。
并在布局资源文件夹工具栏的设置中
<?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" />
我迟到了,但这里有一个解决问题的小方法,而不是编写大量代码或添加庞大的库
转到AndroidManifest.xml
并在首选项活动中添加自定义主题
<activity
android:name=".Dashboard.PreferencepActivity"
android:label="@string/title_activity_preference"
android:theme="@style/Pref"></activity>
<activity
android:name=".Settings"
android:theme="@style/AppTheme.Settings" />
希望有帮助 此方法无法解决添加工具栏的问题,但您可以将默认的ActionBar
返回到设置页面。通过继承父主题,为“设置”活动创建主题
<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>
就这些。Hidro,为什么版面需要一个列表视图?PreferenceActivity
需要一个ListView
和android:id/list
在版面中,如果覆盖版面,这就是为什么。现在我可以让它工作了。谢谢你,@hidro,谢谢你的解释。对我来说没用。。。它确实显示了工具栏,但它位于首选项布局下。在Android 4.4上,我从列表中去掉了填充,因此该活动看起来不像本机活动。什么是AppCompatPreferenceActivity?@Eslam,它是一个扩展首选项活动的类新的'->'设置活动'将显示出来。您在@style/AppTheme.AppBarOverlay
和@style/AppTheme.PopupOverlay
文件中有什么?
