Android /爪哇致命異常主要

Question

我想寫一個簡單的電話簿Android應用程序，當我嘗試運行它，它給了我一堆的錯誤，我真的不知道在哪裏尋找我的錯。所有我試圖讓它立即執行，從一個文件的名稱列表中讀取，並顯示在一個ListView中。這是代碼：

public class MainActivity extends Activity { 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 

     final ListView listview = (ListView) findViewById(R.id.listView1); 
     final ArrayList<String> names = new ArrayList<String>(); 

     try 
     { 
      Scanner sc = new Scanner(getAssets().open(String.format("data.txt"))); 
      while(sc.hasNextLine()) 
      { 
       names.add(sc.nextLine()); 
      } 

     } catch (IOException ioe) { System.out.println("Failed to load file"); } 

     final StableArrayAdapter adapter = new StableArrayAdapter(this, 
       R.id.listView1, names); 

     listview.setAdapter(adapter); 
    } 

    @Override 
    public boolean onCreateOptionsMenu(Menu menu) { 
     // Inflate the menu; this adds items to the action bar if it is present. 
     getMenuInflater().inflate(R.menu.main, menu); 
     return true; 
    } 

    private class StableArrayAdapter extends ArrayAdapter<String> { 

     HashMap<String, Integer> mIdMap = new HashMap<String, Integer>(); 

     public StableArrayAdapter(Context context, int textViewResourceId, 
      List<String> objects) { 
      super(context, textViewResourceId, objects); 
      for (int i = 0; i < objects.size(); ++i) { 
       mIdMap.put(objects.get(i), i); 
      } 
     } 

     @Override 
     public long getItemId(int position) { 
      String item = getItem(position); 
      return mIdMap.get(item); 
     } 

     @Override 
     public boolean hasStableIds() { 
      return true; 
     } 
    } 
} 

這裏是logcat的：

Answer 1

final StableArrayAdapter adapter = new StableArrayAdapter(this, 
       R.id.listView1, names); 

一個ArrayAdapter要擴展需要作爲第二放慢參數的idTextView要填寫，而不是ListView ID。改變它在

final StableArrayAdapter adapter = new StableArrayAdapter(this, 
       android.R.layout.simple_list_item_1, names); 

這裏：

public StableArrayAdapter(Context context, int textViewResourceId, 
      List<String> objects) { 
      super(context, textViewResourceId, objects); 
      for (int i = 0; i < objects.size(); ++i) { 
       mIdMap.put(objects.get(i), i); 
      } 
    } 

，你可以看到你所提供的超級構造ListView的ID。你必須提供一個TextView
