    li.setOnItemClickListener(new OnItemClickListener() { 
    @Override 
    public void onItemClick(AdapterView<?> arg0, View arg1, int position,long arg3) { 
     // TODO Auto-generated method stub 

     int itm=position;

     tv.setText(""+li.getItemAtPosition(position)); 
    } 
});

我希望我能理解你的权利。您希望不同的文字视图具有文字，具体取决于它被点击的字符串的数量。如果是这样，请设置一个静态计数器来计算它被点击的次数。在您的OnItemClick增加此计数器并检查它的值，然后根据它的值设置TextView的文本。

@Override 
public void onItemClick(AdapterView<?> arg0, View arg1, int position,long arg3) { 
    // TODO Auto-generated method stub 

    int itm=position;  
    Toast.makeText(getApplicationContext(),""+itm+""+li.getItemAtPosition(position),40).show(); 
    if (myCounter >=2){ 
     someTextView.setText(""+li.getItemAtPosition(position)); 
    }else{ 
     anotherTextView.setText("blabla")' 
     } 
} 

编辑：让一个ArrayList以正确的顺序持有TextViews。使用OnItemClick中给出的位置int，您可以取出正确的TextView并在它们上使用.setText！

有很多方法可以对付它。

ArrayList<Boolean> firstTimers = new ArrayList<Boolean>(); 

for (Int I =0; I< item.length(); I++){ 
    firstTimers.add(false); 
    } 

li.setOnItemClickListener(new OnItemClickListener() { 
@Override 
public void onItemClick(AdapterView<?> arg0, View arg1, int position,long arg3) { 
    // TODO Auto-generated method stub 

    if(!firstTimers.get(position){ 
     int itm=position;  
     Toast.makeText(getApplicationContext(),""+itm+""+li.getItemAtPosition(position),40).show(); 
      tv.setText(""+li.getItemAtPosition(position)); 
      firstTimers.set(position,true); 
     }else{ // show in other textview 
     } 
} 
});
