本文介绍了如何在回收视图活动之外实施进度条?的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我想显示类似的内容-> 我的家庭活动.在Android里面的Whats中，开始学习，继续前进，有这样的循环视图-> 在此处输入图像说明
I want to display something like this-->My Home activity..inside Whats Android,Start learning ,Get ahead there are recycleviews like this-->enter image description here
如何根据用户阅读情况实现这种进度条?
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();
}
}
查看正在加载改造数据的房屋视图(开始学习活动):
taking one of view of home (Start learning activity) which is loading a retrofit data:
public class StartLearning extends AppCompatActivity {
private RecyclerView recyclerView;
private SLAdapter slAdapter;
ProgressDialog progressDialog;
@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.startlearning_layout);
progressDialog = new ProgressDialog(StartLearning.this);
progressDialog.setMessage("Loading....");
progressDialog.show();
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
if (getSupportActionBar() != null) {
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setDisplayShowHomeEnabled(true);
/*Create handle for the RetrofitInstance interface*/
SLApiSevice service = SLApiClient.getRetrofitInstance().create(SLApiSevice.class);
Call<List<SlModel>> call = service.getMySlmodel();
call.enqueue(new Callback<List<SlModel>>() {
@Override
public void onResponse(Call<List<SlModel>> call, Response<List<SlModel>> response) {
progressDialog.dismiss();
generateDataList(response.body());
}
@Override
public void onFailure(Call<List<SlModel>> call, Throwable t) {
progressDialog.dismiss();
Toast.makeText(getApplicationContext(), "Something went wrong...Please try later!", Toast.LENGTH_SHORT).show();
}
});
}
}
private void generateDataList(List<SlModel> employeeList) {
recyclerView = findViewById(R.id.SLrecycle);
LinearLayoutManager manager = new LinearLayoutManager(getApplicationContext());
recyclerView.setLayoutManager(manager);
recyclerView.setHasFixedSize(true);
slAdapter = new SLAdapter(getApplicationContext(),employeeList);
recyclerView.setAdapter(slAdapter);
}
@Override
public boolean onOptionsItemSelected(@NonNull MenuItem item) {
if (item.getItemId() == android.R.id.home) {
finish();
}
return super.onOptionsItemSelected(item);
}
@Override
public void onBackPressed() {
super.onBackPressed();
}
开始学习适配器:
public class SLAdapter extends RecyclerView.Adapter<SLAdapter.CustomViewHolder> {
List<StartLearning.SlModel> Slmdel;
Context context;
public SLAdapter(Context context,List<StartLearning.SlModel> employees) {
this.Slmdel = employees;
this.context=context;
}
@Override
public CustomViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View itemView = LayoutInflater.from(parent.getContext())
.inflate(R.layout.startlearning_item, parent, false);
return new CustomViewHolder(itemView);
}
@Override
public void onBindViewHolder(CustomViewHolder holder, int position) {
// TipsModel employee = employees.get(position);
//// holder.employeeName.setText(employees.get(position).getTips());
holder.textView.setText(String.valueOf(position+1)+". ");
holder.employeeName.setText(Slmdel.get(position).getTitle());
}
@Override
public int getItemCount() {
return Slmdel.size();
//return (employees == null) ? 0 : employees.size();
}
public class CustomViewHolder extends RecyclerView.ViewHolder {
public TextView employeeName;
TextView textView;
public CustomViewHolder(View view) {
super(view);
employeeName = (TextView) view.findViewById(R.id.Sl2);
textView=view.findViewById(R.id.Sl1);
view.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent intent = new Intent(context, NextSLactivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.putExtra("title", Slmdel.get(getAdapterPosition()).getTitle());
intent.putExtra("idSLnext", Slmdel.get(getAdapterPosition()).getId());
//Log.e("ashwini",WAmdel.get(getAdapterPosition()).getId());
context.startActivity(intent);
}
});
}
}
}
推荐答案
首先，您需要获取数据，但是由于此问题是关于显示具有进度条的圆形进度条，因此您可以这样做
First you need to get Data but as this question is regarding showing circular progressbar with perentage here is how you can do it
1.创建可绘制资源文件 创建一个名为drawing.xml的可绘制资源文件(可绘制资源文件意味着在android studio项目的文件结构中，您会在res文件夹中找到一个名为drawable的文件夹，如下图所示).
1.Creating drawable resource file Create one drawable resource file named circular.xml (drawable resource file means in android studio project’s file structure, you will find a folder named drawable inside a res folder as shown in the below image.)
2.编码circular.xml 将以下代码复制并粘贴到circle.xml
2.Coding circular.xml Copy and paste following code into circular.xml
....
