我已经实现了“将墙纸设置为主屏幕”的实现。但是我没有得到如何将墙纸设置为锁定屏幕和（主屏幕和锁定）两者。在以下代码中，“如果”部分用于设置为主屏幕。是用于“锁定”和“同时（家庭和锁定）” ..将墙纸设置为锁定并且同时将墙纸设置为“家庭和锁定”的逻辑是什么？？

代码：

public class ViewImage extends AppCompatactivity {
Button button1,button2;
public   List<RetroPhoto> product_lists=new ArrayList<>();
private RecyclerView recyclerView;
WallpaperManager myWallpaperManager;

public static FavoriteDatabase favoriteDatabase;
@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.viewimage_layout);

    ImageView mPlace = findViewById(R.id.imagewall);
    button1 = findViewById(R.id.button1);
    button2 = findViewById(R.id.button2);
    ImageButton back = (ImageButton) findViewById(R.id.backToMain);
    ImageButton downloadimage = findViewById(R.id.downloadimg);
    ImageView favimg = findViewById(R.id.favimg);
    recyclerView = findViewById(R.id.rec);
    favoriteDatabase = Room.databaseBuilder(getapplicationContext(),FavoriteDatabase.class,"myfavdb").allowMainThreadQueries().build();
    NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
    assert navigationView != null;
    if (getSupportactionBar() != null) {
        getSupportactionBar().setDisplayHomeAsUpEnabled(true);
        getSupportactionBar().setDisplayShowHomeEnabled(true);
    }

    final Bundle bundle = this.getIntent().getExtras();

    final String imgUrl = bundle.getString("Title");
    Glide.with(this).load(imgUrl)
            .thumbnail(0.5f)
            .crossFade()
            .diskCacheStrategy(DiskCacheStrategy.ALL)
            .into(mPlace);

    back.setOnClicklistener(new View.OnClicklistener() {
        @Override
        public void onClick(View v) {
            onBackpressed();
        }
    });



   button1.setOnClicklistener(new View.OnClicklistener() {

                    {
                        @Override
                        public void onClick(DialogInterface dialogInterface,int i) {
                            // Get the alert dialog selected item's text
                            String selectedItem = Arrays.asList(flowers).get(i);
