Switch语句Android

Question

我的switch语句有问题。当我尝试从列表中选择一个项目时，它将自动执行switch语句的最后一种情况。这里是我的代码：

CustomAdapter.java

@Override 
public View getView(final int position, View convertView, ViewGroup parent) { 
    // TODO Auto-generated method stub 
    Holder holder=new Holder(); 
    View rowView;   
     rowView = inflater.inflate(R.layout.list_field, null); 
     holder.tv2=(TextView) rowView.findViewById(R.id.textView2); 
     holder.tv=(TextView) rowView.findViewById(R.id.titleView); 
     holder.img=(ImageView) rowView.findViewById(R.id.imageView1); 

    holder.tv2.setText(description[position]); 
    holder.tv.setText(result[position]); 
    holder.img.setImageResource(imageId[position]); 

    rowView.setOnClickListener(new View.OnClickListener() { 

     @Override 
     public void onClick(View v) { 

      Intent intent = new Intent(context, Lesson.class); 

      switch(position){              
       case 0: intent.putExtra("Title", l1);     
       case 1: intent.putExtra("Title", l2);     
       case 2: intent.putExtra("Title", l3);     
       case 3: intent.putExtra("Title", l4);     
       case 4: intent.putExtra("Title", l5);     
       case 5: intent.putExtra("Title", l6);     
       case 6: intent.putExtra("Title", l7);     
       case 7: intent.putExtra("Title", l8);     
       case 8: intent.putExtra("Title", l9);     
       case 9: intent.putExtra("Title", l10); 

       context.startActivity(intent);   
      }     
     } 
    }); 

Answer 1

你应该打破

 switch(position){              
      case 0: intent.putExtra("Title", l1); break;     
      case 1: intent.putExtra("Title", l2); break;     
      case 2: intent.putExtra("Title", l3); break;     
      case 3: intent.putExtra("Title", l4); break;     
      case 4: intent.putExtra("Title", l5); break;     
      case 5: intent.putExtra("Title", l6); break;     
      case 6: intent.putExtra("Title", l7); break;     
      case 7: intent.putExtra("Title", l8); break;     
      case 8: intent.putExtra("Title", l9); break;     
      case 9: intent.putExtra("Title", l10); break; 
      default: 
       Log.e("", "no case"); 
       return;       
     }  
      context.startActivity(intent);

你只要给这样在你的程序，它会给只有一个功能...

switch(position){              
      case 0: intent.putExtra("Title", l1);  
        break;    
      case 1: intent.putExtra("Title", l2); 
        break; 
      case 2: intent.putExtra("Title", l3); 
        break; 
      case 3: intent.putExtra("Title", l4);     
        break; 
      case 4: intent.putExtra("Title", l5);     
        break; 
      case 5: intent.putExtra("Title", l6);     
        break; 
      case 6: intent.putExtra("Title", l7); 
        break; 
      case 7: intent.putExtra("Title", l8); 
        break; 
      case 8: intent.putExtra("Title", l9); 
        break; 
      case 9: intent.putExtra("Title", l10); 
        break; 
     }   
context.startActivity(intent);
