androidのonclick中に動的にtextviewを追加します。

Question

私は拡大可能なリストビューを作成しました。親アイテムと子アイテムを含んでいます。プラスまたはマイナスのimageviewをクリックすると、特定の子ネームを取得して次のチェックインアクティビティに渡されます。動的なテキストビューは、以前のアダプタから取得した子の名前に基づいて作成されます。ただし、最後にクリックされた子アイテムの名前のみがそのアクティビティに表示されます。すべての子アイテムの名前をクリックして表示したい場合、そのアイテムの名前がそのアクティビティに動的に表示されます。すべての項目名を表示するには？

public class ExpandListAdapter extends BaseExpandableListAdapter { 

    public Context context;

Checkin_activity：

は、あなたがループそれをために持ってその後

TextView[] textviewArray = new TextView[10]; // Empty Textview array with size 10 

言ってみましょう：あなたはあなたの必要性に従って空のTextViewアレイを作成する必要が

public class Checkinpage extends Activity { 


    public static ArrayList<String> ar=new ArrayList<String>(); 
    public static ArrayList<String> name; 
    public static ArrayList<Movie> movieList; 

    LinearLayout linearLayout; 
    checkinadapter adapter; 
    RecyclerView recycleview; 
    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.checkinpage); 
     Log.d("name12--", String.valueOf(name)); 
     linearLayout=(LinearLayout)findViewById(R.id.linear); 
     recycleview= (RecyclerView) findViewById(R.id.listview); 
     adapter = new checkinadapter(this, movieList); 

     recycleview.setAdapter(adapter); 

     LinearLayoutManager horizontalLayoutManagaer 
       = new LinearLayoutManager(Checkinpage.this, LinearLayoutManager.VERTICAL, false); 
     recycleview.setLayoutManager(horizontalLayoutManagaer); 

    } 


    public class checkinadapter extends RecyclerView.Adapter<checkinadapter.MyViewHolder> { 

     private final Context mcontext; 
     private final ArrayList<Movie> movieItems; 


     public class MyViewHolder extends RecyclerView.ViewHolder { 
      public TextView amount,type,item_count; 
      public ImageView minus,plus; 
      private AdapterView.OnItemClickListener onItemClickListener; 

      public MyViewHolder(View view) { 
       super(view); 

       amount = (TextView) view.findViewById(R.id.amount); 
       type = (TextView) view.findViewById(R.id.type); 

       minus = (ImageView) view.findViewById(R.id.minus); 
       plus = (ImageView) view.findViewById(R.id.plus); 
       item_count = (TextView) view.findViewById(R.id.count); 
      } 

     } 

     public checkinadapter(Context mcontext, ArrayList<Movie> movieItems) { 

      this.mcontext = mcontext; 
      this.movieItems = movieItems; 
     } 

     @Override 
     public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) { 
      View itemView = LayoutInflater.from(parent.getContext()) 
        .inflate(R.layout.checkin_list, parent, false); 


      return new MyViewHolder(itemView); 
     } 

     @Override 
     public void onBindViewHolder(final MyViewHolder holder, final int position) { 


      final Movie m = movieItems.get(position); 


      if (m.getcheckin_name()!=null) 
      { 
       if (!m.getcheckin_name().equals("null")) 
       { 
        holder. type.setText(m.getcheckin_name()); 
       }} 
//   if (m.getRes_deliverytime()!=null) 
//   { 
//    if (!m.getRes_deliverytime().equals("null")) 
//    { 
//     holder.time.setText(m.getRes_deliverytime()+ " mins"); 
//    }} 
//// 

     } 


     @Override 
     public int getItemCount() { 
      return movieItems.size(); 
     } 
    } 



} 

Answer 1

Add this in to your project dependencies (build.gradle) 
compile 'com.google.code.gson:gson:2.2.4' 


checkin.setOnClickListener(new View.OnClickListener() { 
    @Override 
    public void onClick(View view) { 
    Intent i=new Intent(context,Checkinpage.class); 
    Gson gsonMovie = new Gson(); 
    String strMovie = gsonMovie.toJson(movieList); 
    Bundle bundle = new Bundle(); 
    bundle.putString("Movies", strMovie); 
    intent.putExtras(bundle);  
    context.startActivity(i); 
     } 
}); 

：

 ArrayList<Movie> movieList=new ArrayList<Movie>(); 
     Bundle bundle = this.getIntent().getExtras(); 
     Gson gson = new Gson(); 
     Type type = new TypeToken<ArrayList<Movie>>() { 
     }.getType(); 
     movieList = gson.fromJson(
       bundle.getString("Movies"), type); 

あなたはリストビューを使用するか、ArrayListの項目

Answer 2

LinearLayoutでTextviewを動的に追加：

for (int i = 0; i < 10; i++) { 

    TextView tv = new TextView(this); // Create Textview 
    tv.setText("Set Child Name Here As Per i Value"); 
    linearLayout.addView(tv); 
    textviewArray [i] = tv; // save reference of your Textview 
} 

ご希望の場合はお手数ですが、 Checkin_activityで
