Settings添加1级菜单并实现跳转

android 11

方案一：

XML配置

packages/apps/Settings/res/xml/top_level_settings.xml

<Preference
        android:key="buttons_key"
        android:title="@string/buttons_title"
	    android:summary="@string/buttons_title"
        android:icon="@drawable/ic_buttons"
        android:order="-5">
	<intent android:action="android.intent.action.MAIN"
	        android:targetPackage="要跳转的包名"
	        android:targetClass="要跳转的类名" />
    </Preference>

或者

<Preference
        android:key="buttons_key"
        android:title="@string/buttons_title"
	    android:summary="@string/buttons_title"
        android:icon="@drawable/ic_buttons"
        android:order="-5">
	    android:fragment="fragment"
        settings:controller="Controller"
    </Preference>

NewPreferenceController.java

package com.android.settings.new;

import android.content.Context;
import android.os.Build;

import com.android.settings.core.BasePreferenceController;

public class StatusPreferenceController extends BasePreferenceController {

    public StatusPreferenceController(Context context, String key) {
        super(context, key);
    }

    @Override
    public int getAvailabilityStatus() {
    //控制菜单是否显示
        return AVAILABLE;
    }

    @Override
    public CharSequence getSummary() {
       return "Build.VERSION.RELEASE";
    }
}

NewFragment.java

package  com.android.settings.new;

import android.app.settings.SettingsEnums;
import android.content.Context;
import com.android.settings.R;
import com.android.settings.dashboard.DashboardFragment;
public class NewFragment extends DashboardFragment {

    @Override
protected int getPreferenceScreenResId() {
//添加子菜单布局,就是你要加载的那个xml，点击菜单后显示的内容
        return R.xml.new_xml;
}

    @Override
    protected String getLogTag() {
        return "NewFragment_LOG";
    }

    @Override
    public int getMetricsCategory() {
        return 0;//这里切记不能<0否则子菜单中配置Fragment时候会报错
    }
}
