实现目标：在设置里面新增一个选项无标题，在里面实现点击事件，swtch事件，单选事件，多选事件

1、设置界面的布局文件packages/apps/Settings/res/xml/top_level_settings.xml，在这里面添加自定义的选项

    <com.android.settings.widget.HomepagePreference
        android:fragment="com.android.settings.myceshi.MySettingsCeshi"
        android:icon="@drawable/ic_help"
        android:key="top_level_my_setting"
        android:order="40"
        android:title="无标题"
        android:summary="无标题"/>

 

2、在packages/apps/Settings/res/drawable下创建图标 ，创建一个名为ic_help.xml文件，里面代码如下

        android:fillType="evenOdd"
        android:fillColor="?android:attr/colorPrimary"/>
</vector>

 3、在packages/apps/Settings/src/com/android/settings下创建一个名为myceshi的文件夹，在这个文件内创建MySettingsCeshi.java

package com.android.settings.myceshi;

import android.app.settings.SettingsEnums;
import android.content.Context;
import android.content.Intent;
import android.content.res.Resources;
import android.graphics.Canvas;
import android.graphics.Color;
import android.graphics.Paint;
import android.graphics.PixelFormat;
import android.graphics.PorterDuff;
import android.graphics.Typeface;
import android.os.Handler;
import android.os.Bundle;
import android.provider.Settings;
import android.util.Log;
import android.view.Gravity;
import android.view.WindowManager;
import android.view.ViewGroup.LayoutParams;
import android.widget.TextView;

import androidx.preference.ListPreference;
import androidx.preference.Preference;
import androidx.preference.SwitchPreference;

import com.android.settings.R;
import com.android.settings.SettingsActivity;
import com.android.settings.dashboard.DashboardFragment;
import com.android.settings.search.BaseSearchIndexProvider;
import com.android.settingslib.search.SearchIndexable;
import android.widget.Toast;
import android.app.Dialog;

@SearchIndexable
public class MySettingsCeshi extends DashboardFragment implements Preference.OnPreferenceClickListener,Preference.OnPreferenceChangeListener{
    
    private static final String TAG = "mysettingsceshi";
    private Toast mDevHitToast;
    private SwitchPreference mShow;

     @Override
    public void onCreate(Bundle icicle) {
        super.onCreate(icicle);
        mDevHitToast = null;

        mShow = (SwitchPreference) findPreference("myFunction2");
        mShow.setOnPreferenceChangeListener(this);
        Preference mPreference = findPreference("myFunction1");
        mPreference.setOnPreferenceClickListener(this);
    }

    @Override
    public boolean onPreferenceClick(Preference preference) {
        Log.e("onPreferenceClick","走了点击时间2");
        Toast.makeText(getActivity(), "Preference Clicked", Toast.LENGTH_SHORT).show();
        return true;
    }

    @Override
    public boolean onPreferenceChange(Preference preference, Object newValue) {
        boolean show = (boolean)newValue;
        if(show==true){
            Toast.makeText(getActivity(), "已打开", Toast.LENGTH_SHORT).show();
        }else{
            Toast.makeText(getActivity(), "已关闭", Toast.LENGTH_SHORT).show();
        }
         return true;
    }

    @Override
    protected String getLogTag() {
        return TAG;
    }

    @Override
    protected int getPreferenceScreenResId() {
        return R.xml.my_settings_ceshi;
    }

    @Override
    public int getMetricsCategory() {
        return 5;
    }

    /**
     * For Search.
     */
    public static final BaseSearchIndexProvider SEARCH_INDEX_DATA_PROVIDER =
            new BaseSearchIndexProvider(R.xml.my_settings_ceshi);

}

4、在packages/apps/Settings/res/xml下创建给MySettingsCeshi.java类用的布局文件，命名为my_settings_ceshi.xml

<?xml version="1.0" encoding="utf-8"?>
<PreferenceScreen
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:settings="http://schemas.android.com/apk/res-auto"
    android:title="展示内容">

        <Preference
            android:key="myFunction1"
            android:order="44"
            android:title="功能其一"
            android:summary="功能其一"/>

        <SwitchPreference
            android:key="myFunction2"
            android:order="45"
            android:title="功能其二"
            android:summary="功能其二"/>

        <com.android.settings.myceshi.PrivateDialogPreference
            android:key="myFunction3"
            android:order="46"
            android:title="功能其三"
            android:summary="功能其三"
            android:dialogLayout="@layout/my_dialog"/>

        <com.android.settings.myceshi.PrivateDialogPreference2
            android:key="myFunction4"
            android:order="47"
            android:title="功能其四"
            android:summary="功能其四"
            android:dialogLayout="@layout/my_dialog2"/>

    </PreferenceScreen>

5、在packages/apps/Settings/src/com/android/settings/myceshi下创建PrivateDialogPreference.java类给功能其三（单选布局）使用

package com.android.settings.myceshi;

import android.app.settings.SettingsEnums;
import android.content.ActivityNotFoundException;

import com.android.settingslib.RestrictedLockUtilsInternal;

import com.google.common.net.InternetDomainName;

import java.util.HashMap;
import java.util.Map;
import android.widget.Toast;

public class PrivateDialogPreference extends CustomDialogPreferenceCompat implements RadioGroup.OnCheckedChangeListener,View.OnClickListener{

    private EditText mEditText;
    private RadioGroup mRadioGroup;
    private Button Button1,Button2;


    public PrivateDialogPreference(Context context, AttributeSet attrs) {
        super(context, attrs);
        // 初始化设置
    }

     @Override
    protected void onBindDialogView(View view) {
        mEditText = view.findViewById(R.id.private_dns_mode_provider_hostname);
        mRadioGroup = view.findViewById(R.id.private_dns_radio_group);
        mRadioGroup.setOnCheckedChangeListener(this);

        final RadioButton offRadioButton = view.findViewById(R.id.private_dns_mode_off);
        offRadioButton.setText("单选按钮一");

        final RadioButton opportunisticRadioButton = view.findViewById(R.id.private_dns_mode_opportunistic);
        opportunisticRadioButton.setText("单选按钮二");

        final RadioButton providerRadioButton = view.findViewById(R.id.private_dns_mode_provider);
        providerRadioButton.setText("单选按钮三");

        final TextView helpTextView = view.findViewById(R.id.private_dns_help_info);
        helpTextView.setMovementMethod(LinkMovementMethod.getInstance());

        Button1 = view.findViewById(R.id.button1);
        Button1.setOnClickListener(this);

        Button2 = view.findViewById(R.id.button2);
        Button2.setOnClickListener(this);
    }

	public void onClick(View v) {
        int viewId = v.getId();
        if (viewId == R.id.button1) {
            Toast.makeText(getContext(), "点击了取消", Toast.LENGTH_SHORT).show();
            // getContext().dismiss();
        } else if (viewId == R.id.button2) {
            Toast.makeText(getContext(), mEditText.getText().toString(), Toast.LENGTH_SHORT).show();

        }
    }

    @Override
    public void onCheckedChanged(RadioGroup group, int checkedId) {
        if (checkedId == R.id.private_dns_mode_off) {
            Toast.makeText(getContext(), "选择了单选按钮一", Toast.LENGTH_SHORT).show();
        } else if (checkedId == R.id.private_dns_mode_opportunistic) {
            Toast.makeText(getContext(), "选择了单选按钮二", Toast.LENGTH_SHORT).show();
        } else if (checkedId == R.id.private_dns_mode_provider) {
            Toast.makeText(getContext(), "选择了单选按钮三", Toast.LENGTH_SHORT).show();
        }else if (checkedId == R.id.button1) {
            Toast.makeText(getContext(), "点击了取消", Toast.LENGTH_SHORT).show();
            // mMode = PRIVATE_DNS_MODE_PROVIDER_HOSTNAME;
        }else if (checkedId == R.id.button2) {
            Toast.makeText(getContext(), "点击了确认", Toast.LENGTH_SHORT).show();
            // if(mEditText.getText().toString() == ""){
            //     Toast.makeText(getContext(), "无内容", Toast.LENGTH_SHORT).show();
            // }else{
            //     Toast.makeText(getContext(),mEditText.getText().toString(), Toast.LENGTH_SHORT).show();
            // }
        }
    }
}

5、在packages/apps/Settings/res/layout下创建布局文件my_dialog.xml文件给到PrivateDialogPreference.java（功能其三）

                style="@android:style/Widget.CompoundButton.RadioButton"
                android:imeOptions="actionDone"
                android:inputType="textFilter|textUri"

            android:layout_height="wrap_content"
            android:orientation="horizontal"
            android:padding="8dp">
            <Button
                android:id="@+id/button1"
                android:layout_width="wrap_content"
