致命例外：main：java.lang.RuntimeException：

不幸的是，应用程序已越过我收到的消息。我使用Yamba应用程序并尝试使用ViewBinder在timelineActivity中使用relativeTimeSpan发布状态消息。以下是LogCat：致命例外：main：java.lang.RuntimeException：

我注意到错误是在TimelineActivity.Java的第42行，但无法解决。

import android.app.ListActivity; 
    import android.database.Cursor; 
    import android.os.Bundle; 
    import android.support.v4.widget.SimpleCursorAdapter; 
    import android.text.format.DateUtils; 
    import android.view.View; 
    import android.widget.SimpleCursorAdapter.ViewBinder; 
    import android.widget.TextView; 

public class TimelineActivity extends Activity { 
     static final String[] FROM = { StatusData.C_USER, StatusData.C_CREATED_AT, 
       StatusData.C_TEXT }; 
     static final int[] TO = { R.id.text_user, R.id.text_created_at, 
       R.id.text_text }; 

     SimpleCursorAdapter adapter; 
     Cursor cursor; 

     @SuppressWarnings("deprecation") 
     protected void onCreate(Bundle savedInstanceState) { 
      super.onCreate(savedInstanceState); 
      setContentView(R.layout.timeline); 

      cursor = ((YambaApp) getApplication()).statusData.Query(); 

    //Line 42 adapter = new SimpleCursorAdapter(this, R.layout.row, cursor, FROM, TO); 
      adapter.setViewBinder((android.support.v4.widget.SimpleCursorAdapter.ViewBinder) VIEW_BINDER); 
      list.setAdapter(adapter); 

     } 

     static final ViewBinder VIEW_BINDER = new ViewBinder() { 

      @Override 
      public boolean setViewValue(View view, Cursor cursor, int columnIndex) { 
       if (view.getId() != R.id.text_created_at) 
        return false; 

       long time = cursor.getColumnIndex(StatusData.C_CREATED_AT); 
       CharSequence relativeTime = DateUtils 
         .getRelativeTimeSpanString(time); 
       ((TextView) view).setText(relativeTime); 

       return true; 
      } 

     }; 

    }

让我知道你需要的任何其他信息..

哪条线路是42？ – cbrulak

添加第42行以上为你的目光 –

你的错误是在下一行不在这 –

尝试使用以下

final android.support.v4.widget.SimpleCursorAdapter.ViewBinderVIEW_BINDER = new ViewBinder()

我想你已经输入了错误的viewbinder

现在张贴进口。 ..它有正确的查看人已经 –

酷......大于X StinePike。我搞砸了进口...现在它工作正常 –

欢迎:) – stinepike

变化：

import android.widget.SimpleCursorAdapter.ViewBinder;

至：

import android.support.v4.widget.SimpleCursorAdapter.ViewBinder;
