Android 如何在FAB click上的单独活动中显示喜爱的内容？

以下是我的回收者的心脏视图适配器代码（切换按钮）：

以下是custom_Layout.xml的布局文件：

以下是模型类别代码：

}

我点击晶圆厂后，如何在单独的活动中显示喜爱的内容

fab.setOnClickListener(new View.OnClickListener() { 
    @Override public void onClick(View view) { 
        Toast.makeText(getActivity(), "FAB", Toast.LENGTH_SHORT).show(); 

        ArrayList<ToggleModel> favoriteList = new ArrayList<>();
        for(ToggleModel model: toggleModelList) {
            if(model.isFavorite())
                favouriteList.add(model);
        }

        Intent intent = new Intent(getActivity(), FavoritedActivity.class);
        intent.putExtra("FAVOURITE_LIST", (Serializable) favouriteList);
        startActivity(intent); 
    } 
});

请提供您的宝贵意见/建议

首先，使您的

ToggleModel

可序列化，以便通过

Intent

public class ToggleModel implements Serializable {
    ...
}

然后找出最喜欢的项目并将其传递给下一个活动

fab.setOnClickListener(new View.OnClickListener() { 
    @Override public void onClick(View view) { 
        Toast.makeText(getActivity(), "FAB", Toast.LENGTH_SHORT).show(); 

        ArrayList<ToggleModel> favoriteList = new ArrayList<>();
        for(ToggleModel model: toggleModelList) {
            if(model.isFavorite())
                favouriteList.add(model);
        }

        Intent intent = new Intent(getActivity(), FavoritedActivity.class);
        intent.putExtra("FAVOURITE_LIST", (Serializable) favouriteList);
        startActivity(intent); 
    } 
});

如果只想获取文本，例如标题，请按照以下步骤操作：

fab.setOnClickListener(new View.OnClickListener() { 
    @Override public void onClick(View view) { 
        Toast.makeText(getActivity(), "FAB", Toast.LENGTH_SHORT).show(); 

        ArrayList<String> favoriteList = new ArrayList<>();
        for(ToggleModel model: toggleModelList) {
            if(model.isFavorite())
                favouriteList.add(model.getTitle());
        }

        Intent intent = new Intent(getActivity(), FavoritedActivity.class);
        intent.putStringArrayListExtra("FAVOURITE_LIST", favouriteList);
        startActivity(intent); 
    } 
});

将喜爱的内容保存在数据库中，然后将其放入您的

FavoritedActivity

我可以对putExtra和getStringExtra执行同样的操作吗？使用数据库更可靠，请考虑用户希望在您的<>代码> ActudieDebug < /Cord> @ MohammadSianaki中不喜欢的项目，请提供代码或任何GIDIDI实现这样的日志：Log.e（“FAVVV:，favoriteList.toString（））；星触觉（意向）；我得到这个日志：com.zedapps.elon。ToggleModel@e619734，com.zedapps.elon。ToggleModel@1d7695d，如果您只想获取标题部分，如何获取文本检查我的更新答案。

public class ToggleModel implements Serializable {
    ...
}

fab.setOnClickListener(new View.OnClickListener() { 
    @Override public void onClick(View view) { 
        Toast.makeText(getActivity(), "FAB", Toast.LENGTH_SHORT).show(); 

        ArrayList<ToggleModel> favoriteList = new ArrayList<>();
        for(ToggleModel model: toggleModelList) {
            if(model.isFavorite())
                favouriteList.add(model);
        }

        Intent intent = new Intent(getActivity(), FavoritedActivity.class);
        intent.putExtra("FAVOURITE_LIST", (Serializable) favouriteList);
        startActivity(intent); 
    } 
});

@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_favorite);

    ArrayList<ToggleModel> favoriteList = (ArrayList<ToggleModel>) getIntent().getSerializableExtra("FAVOURITE_LIST"); 

    //Your favorite list is here. Now call the adapter and attach with recyclerview to show this

    ...
}

fab.setOnClickListener(new View.OnClickListener() { 
    @Override public void onClick(View view) { 
        Toast.makeText(getActivity(), "FAB", Toast.LENGTH_SHORT).show(); 

        ArrayList<String> favoriteList = new ArrayList<>();
        for(ToggleModel model: toggleModelList) {
            if(model.isFavorite())
                favouriteList.add(model.getTitle());
        }

        Intent intent = new Intent(getActivity(), FavoritedActivity.class);
        intent.putStringArrayListExtra("FAVOURITE_LIST", favouriteList);
        startActivity(intent); 
    } 
});

@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_favorite);

    ArrayList<String> favoriteList = (ArrayList<String>) getIntent().getStringArrayListExtra("FAVOURITE_LIST"); 

    //Your favorite list of title is here. Now call the adapter and attach with recyclerview to show this
