android에서 textview를 동적으로 추가하십시오.

Question

확장 가능한 목록보기를 만들었습니다. 상위 항목과 하위 항목을 포함하고 있습니다. 더하기 또는 빼기 imageview를 클릭하면 특정 하위 이름을 받아 다음 체크인 활동으로 넘어갑니다. 동적 텍스트 뷰는 이전 어댑터의 검색된 하위 이름을 기반으로 작성됩니다. 그러나 마지막으로 클릭 한 하위 항목 이름 만 해당 활동에 표시됩니다. 클릭 한 하위 항목 이름을 모두 표시하고 그 항목 이름이 해당 활동에 동적으로 표시됩니다. 모든 항목 이름을 표시하려면 어떻게합니까?

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); 

당신이 목록보기를 사용하거나 ArrayList의 항목

Answer 2

LinearLayout에서 Textview를 동적으로 추가 :

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 
} 

희망이 있으면 도움이 될 것입니다. Checkin_activity에서
