讓問題在Android中的ListView

-1

tv=(TextView) findViewById(R.id.ringtone); 
    if (!hasErrors) { 

     setListAdapter(new ArrayAdapter<String>(FindFilesByType.this, R.layout.main, 
       Ringtones)); 

     lv.setOnItemClickListener(new OnItemClickListener() { 
      @Override 
      public void onItemClick(AdapterView<?> aView, View v, 
        int position, long id) { 
       currentPosition = position; 
       playRingtone(DIRECTORY+Ringtones.get(position)); 
      } 
     });

但我得到以下logcat的和我的應用程序關閉強制關閉

你可以發佈你的lay out XML？你確定'R.id.ringtone'是指TextView嗎？ – Bostone 2011-04-27 05:48:29

的logcat中明確指出，你需要爲一個TextView，那裏的東西你提供一個LinearLayout中提供的資源ID （我的猜測，因爲它拋出ClassCastException）我相信你main.xml是一個linearlayout而不是一個textview。而不是嘗試R.id.ringtone

你的問題是在這些線路中描述

感謝：

11:05:08.473: ERROR/AndroidRuntime(715): Caused by: java.lang.ClassCastException: android.widget.LinearLayout 
04-27 11:05:08.473: ERROR/AndroidRuntime(715):  at android.widget.ArrayAdapter.createViewFromResource(ArrayAdapter.java:340)

這可能意味着你正在使用的LinearLayout，而不是一個。
（你最讓你做一些像
foobar = (LinearLayout) someCode();一個ClassCastException的時間）

好朋友你的問題是你使用r.layout.main列表行。

你必須創建在這裏你只提的TextView 一個separete listrow佈局，並把它作爲一個佈局你的錯誤是在這條線

setListAdapter(new ArrayAdapter<String>(FindFilesByType.this, R.layout.main, 
       Ringtones));

創建佈局說listrow.xml

<?xml version="1.0" encoding="utf-8"?> 
<TexView 
..... 
/>

並更換你的線

setListAdapter(new ArrayAdapter<String>(FindFilesByType.this, R.layout.listrow, 
        Ringtones));

好的我得到的解決方案： - this.lv1.setAdapter（new ArrayAdapter （FindFilesByType.this，android.R.layout.test_list_item，Ringtones））; – Android 2011-04-27 06:06:30
