如何在回收视图活动之外实现进度条？ [关闭]

Question

我想显示这样的东西-->My Home activity..inside Whats Android，开始学习，前进有这样的recycleviews-->enter image description here

如何实现这种基于用户阅读的进度条？？

我的家庭活动：

public class MainActivity extends AppCompatActivity {

private RecyclerView recyclerview ;
private String[] names ;
private TypedArray profile_pics ;
private TypedArray card_images;
 ImageView imageView;

private List<Member> memberList ;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super .onCreate(savedInstanceState);
    setContentView(R.layout. activity_main );
    imageView=findViewById(R.id.search);

   Toolbar toolbar = (Toolbar) findViewById(R.id. toolbar );
   setSupportActionBar( toolbar );
    names = getResources().getStringArray(R.array. names );
    profile_pics = getResources().obtainTypedArray(R.array. profile_pics );
    card_images=getResources().obtainTypedArray(R.array.card_images);
    memberList = new ArrayList<>();
    for (int i = 0; i < names.length; i++) {
        Member member = new Member( names [i], profile_pics .getResourceId(i, -1),card_images.getResourceId(i,-1));
        memberList .add( member );
    }
    recyclerview = (RecyclerView) findViewById(R.id. recyclerview );
    LinearLayoutManager layoutManager = new LinearLayoutManager(MainActivity.this);
    recyclerview.setLayoutManager( layoutManager );
    MainAdapter adapter = new MainAdapter(memberList, MainActivity.this);
    recyclerview .setAdapter( adapter );
    imageView.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Intent intent=new Intent(getApplicationContext(),Search.class);
            intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

            getApplicationContext().startActivity(intent);
        }
    });}}

家庭活动适配器：

public class MainAdapter extends RecyclerView.Adapter<MainAdapter.MemberViewHolder> {
private List<Member> members ;
private Context context ;
public MainAdapter(List<Member> members , Context context ) {
    this. members = members;
    this. context = context;
}
public class MemberViewHolder extends RecyclerView.ViewHolder {
    private CardView cardView ;
    private TextView name_tv ;
    private ImageView email_tv ;
    private ImageView pic_iv ;
    public MemberViewHolder(View itemView) {
        super (itemView);
        cardView = (CardView) itemView.findViewById(R.id. cv );
        name_tv = (TextView) itemView.findViewById(R.id. member_name );
        email_tv=(ImageView) itemView.findViewById(R.id.thumbnail);
        pic_iv = (ImageView) itemView.findViewById(R.id. profile_pic );
    }
  }

@Override
public void onBindViewHolder(MemberViewHolder memberViewHolder, int i) {
    final int pos = i;
    memberViewHolder. name_tv .setText(members.get(i).getName());
    memberViewHolder.email_tv.setImageResource(members.get(i).getCards());
    memberViewHolder. pic_iv .setImageResource(members.get(i).getPhotoID());
    memberViewHolder.itemView.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            if(pos == 0){
                view.getContext().startActivity(new Intent(view.getContext(), Introduction.class));
            }

            else if(pos == 1){
                view.getContext().startActivity(new Intent(view.getContext(), WhatsAndroid.class));
            }

            else if(pos == 2){
                view.getContext().startActivity(new Intent(view.getContext(), StartLearning.class));
            }
            else if(pos == 3){
                view.getContext().startActivity(new Intent(view.getContext(), GetAhead.class));
            }

            else if(pos == 4){
                view.getContext().startActivity(new Intent(view.getContext(), TipsandTricks.class));
            }
            else if (pos==5)
            {
                view.getContext().startActivity(new Intent(view.getContext(), Interview.class));

            }
        }
    });
}
@Override
public MemberViewHolder onCreateViewHolder(ViewGroup viewGroup, int i) {
    View view = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout. cardview_row_item , viewGroup, false);
    MemberViewHolder memberViewHolder = new MemberViewHolder(view);
    return memberViewHolder;
}
@Override
public int getItemCount() {
    return members.size();
 }
}

Answer 1

首先更改您的适配器 CardView 项目以包含此 CircleProgressBar，然后您可以为每个项目设置进度级别

Answer 2

首先您需要获取数据，但由于这个问题是关于显示带有百分比的圆形进度条，因此您可以这样做

1.创建可绘制资源文件 创建一个drawable资源文件，命名为circular.xml（drawable资源文件是指在android studio项目的文件结构中，你会在res文件夹中找到一个名为drawable的文件夹，如下图所示。）

2.编码circular.xml 将以下代码复制并粘贴到 circular.xml 中

Code
