無法從sqlite中獲取值並將其設置爲TextView

Question

我想知道我的代碼波紋管有什麼問題，爲什麼我無法將colums＃5 setText中的sqlite值設置爲TextView？

//Adapter SQLite 
public Cursor getFRUIT_LEVEL_EASY_STEP_2() 
{ 
    Cursor step_2 = sqLiteDatabase.rawQuery("SELECT count(*) FROM FRUIT WHERE " + KEY_LEVEL + "='Easy' AND " + KEY_LEVEL_STEP + "=1", null); 
    return step_2; 
} 

final TextView l1 = (TextView) findViewById(R.id.l1); 
mySQLiteAdapter = new SQLiteAdapter(this); 
mySQLiteAdapter.openToRead(); 

step_2 = mySQLiteAdapter.getFRUIT_LEVEL_EASY_STEP_2(); 
step_2.moveToFirst(); 

int count2 = step_2.getInt(0); 

// Here i want to get value Int from clumns #5 
int score =step_2.getInt(5); 

if(count2 != 0) 
    { 
     l1.setText(Integer.toString(score)); 

    } 

step_2.close(); 
mySQLiteAdapter.close(); 

爲什麼我無法獲得價值？這段代碼有什麼問題？

Answer 1

使用下面的代碼

l1.setText(String.valueOf(score)); 

Answer 2

而不是l1.setText（Integer.toString（score））;

use l1.setText（「」+ Integer.toString（score））;

可能這個幫助你
