MainActivity.class 작동하지 않습니다

행 레이아웃.xml

죄송합니다. 이것은 내 모든 코드입니다. 나는 android:focusable="false", android:focusableInTouchMode="false" 같은 모든 태그를 목록보기의 행에 추가했으며 목록보기의 루트 레이아웃에는 android:descendantFocusability="blocksDescendants"을, 은 listView.setOnItemClickListener 앞에 코드로 추가했습니다.이 onitem 클릭 리스너 doe는 작동하지 않고 응답이 없습니다.

Answer 1

당신이 경우 모든 코드가 정확하고도 아무런 예외 코드에 남아 없지만 ItemClickListener에 ListView를 다음 작동하지 않는 경우 다음을 실행하면/
다시 시작을 사용하여 캐시에게 안드로이드 스튜디오에서 사용할 수있는 옵션을 무효화 할 필요가 Listview 프로젝트에서 OnItemClick Listener가 올바르게 작동합니다. android studio의 왼쪽 상단에있는 File Option을 클릭하여 invalidate caches/restart 옵션을 선택하십시오.

Answer 2

 add this in Activity [updated] 

     customAdapter = new CustomAdapter(this, memeTitles, image, memeDescriptions,new View.OnClickListener() { 
        @Override 
        public void onClick(View view) { 
     int i=(Integer)view.getTag(); 
         Toast.makeText(MainActivity.this, "you clicked" + i, Toast.LENGTH_LONG).show(); 
         Log.d("onitemclick Listener","called"); 
        } 


       }); 
       listView.setAdapter(customAdapter); 

     And add id as rootLayout in row xml 

     public class CustomAdapter extends ArrayAdapter<String> { 
      Context context; 
      int[] images; 
      String[] titleArray; 
      String[] descriptionArrayl; 
    OnClickListener onClickListener; 
      public CustomAdapter(Context c,String[] memeTitles,int[] imgs,String[] descriptionArrayl,OnClickListener onClickListener) { 
     super(c,R.layout.row,R.id.etTitle,memeTitles); 
       this.context=c; 
       this.images = imgs; 
       this.titleArray = memeTitles; 
       this.descriptionArrayl=descriptionArrayl; 
       this.onClickListener=onClickListener; 
      } 
      //Sub class of CustomAdapter 
      class MyViewHolder{ 
       ImageView myImage; 
       TextView myTitle; 
       TextView myDescription; 
       RelativeLayout rootLayout; 
       MyViewHolder(View v){ 
     rootLayout=(RelativeLayout)v.findViewById(R.id.rootLayout); 
        myImage= (ImageView) v.findViewById(R.id.imageView); 
        myTitle = (TextView) v.findViewById(R.id.etTitle); 
        myDescription = (TextView) v.findViewById(R.id.etDescriptions); 
       } 
      } 

      //Get View Method of CustomAdapter class 
      public View getView(int position, View convertView, ViewGroup parent){ 
       View row=convertView; 
       MyViewHolder myViewHolder =null; 
       if (row==null) { 
        LayoutInflater inflater = (LayoutInflater) context.getSystemService(context.LAYOUT_INFLATER_SERVICE); 
        row = inflater.inflate(R.layout.row, parent, false); 
        myViewHolder = new MyViewHolder(row); 
        Log.d("List View","Creating New Row"); 
        row.setTag(myViewHolder); 
       }else { 
        myViewHolder = (MyViewHolder) row.getTag(); 
        Log.d("List View","Recycling Stuff"); 

       } 
       myViewHolder.myImage.setImageResource(images[position]); 
       myViewHolder.myTitle.setText(titleArray[position]); 
       myViewHolder.myDescription.setText(descriptionArrayl[position]); 
     rootLayout.setTag(position); 
     rootLayout.setOnClickListener(onClickListener); 

       return row; 
      } 
     }
