Android 8.0 Settings往界面添加菜单

1、SettingsActivity.java 文件下的doUpdateTilesList方法里添加：

setTileEnabled(new ComponentName(packageName,

	Settings.WtkSecurityLockersActivity.class.getName()),

	getResources().getBoolean(R.bool.show_security_lock), isAdmin);

2、Settings.java文件下添加

public static class WtkSecurityLockersActivity extends SettingsActivity { }

3、打开SettingsGateway.java文件，

在ENTRY_FRAGMENTS数组中添加：WtkSecurityLocker.class.getName(),

在SETTINGS_FOR_RESTRICTED中添加：Settings.WtkSecurityLockersActivity.class.getName(),

4、在AndroidManifest.xml中添加

<activity android:name=".Settings$WtkSecurityLockersActivity"

	android:taskAffinity="com.android.settings"

	android:label="@string/security_locker"

	android:icon="@drawable/ic_wtk_securitylocker"

	android:parentActivityName="Settings">

	<intent-filter android:priority="1">

		<action android:name="android.settings.WIRELESS_SETTINGS" />

		<action android:name="android.settings.AIRPLANE_MODE_SETTINGS" />

		<category android:name="android.intent.category.DEFAULT" />

	</intent-filter>

	<intent-filter>

		<action android:name="android.intent.action.MAIN" />

		<category android:name="android.intent.category.DEFAULT" />

		<category android:name="android.intent.category.VOICE_LAUNCH" />

	</intent-filter>

	<intent-filter android:priority="11">

		<action android:name="com.android.settings.action.SETTINGS"/>

	</intent-filter>

	<meta-data android:name="com.android.settings.category"

		android:value="com.android.settings.category.ia.homepage"/>

	<meta-data android:name="com.android.settings.FRAGMENT_CLASS"

		android:value="com.android.settings.WtkSecurityLocker"/>

	<meta-data android:name="com.android.settings.PRIMARY_PROFILE_CONTROLLED"

		android:value="true" />

</activity>

5、最后在Settings下添加一个WtkSecurityLocker类，实现该类。

6、如果需要动态改变菜单的Summary，需要在WtkSecurityLocker.java里面添加：

import com.android.settings.dashboard.SummaryLoader;

import android.content.Context;

import android.app.Activity;



private static class SummaryProvider implements SummaryLoader.SummaryProvider {



	private final Context mContext;

	private final SummaryLoader mLoader;



	private SummaryProvider(Context context, SummaryLoader loader) {

		mContext = context;

		mLoader = loader;

	}



	@Override

	public void setListening(boolean listening) {

		if (listening) {

			updateSummary();

		}

	}



	private void updateSummary() {

		mLoader.setSummary(this, "Summary");

	}

}



public static final SummaryLoader.SummaryProviderFactory SUMMARY_PROVIDER_FACTORY = new SummaryLoader.SummaryProviderFactory() {

	@Override

	public SummaryLoader.SummaryProvider createSummaryProvider(Activity activity, SummaryLoader summaryLoader) {

		return new SummaryProvider(activity, summaryLoader);

	}

};
