找不到Android资源异常

Question

我的应用程序代码如下，

public class Alarm extends MainActivity {

public String str;

public void onReceive(Context context, Intent intent) {
    //---get the CB message passed in---
    Bundle bundle = intent.getExtras();        
    SmsCbMessage[] msgs = null;
    str = "";            
    if (bundle != null)  {
        //---retrieve the SMS message received---
        Object[] pdus = (Object[]) bundle.get("pdus");
        msgs = new SmsCbMessage[pdus.length];            
        for (int i=0; i<msgs.length; i++) {
            msgs[i] = SmsCbMessage.createFromPdu((byte[])pdus[i]);                
            str += "CB " + msgs[i].getGeographicalScope() + msgs[i].getMessageCode() + msgs[i].getMessageIdentifier() + msgs[i].getUpdateNumber();                     
            str += " :";
            str += "\n";        
        }
        }
        }


EditText user_value;
Button startalarm;


@Override
 public void onCreate(Bundle savedInstanceState) 
{
 super.onCreate(savedInstanceState);
 setContentView(R.layout.third);

startalarm = (Button) findViewById(R.id.startalarm);
user_value = (EditText) findViewById(R.id.user_value);

startalarm.setOnClickListener(new View.OnClickListener() 
{

public void onClick(View arg0)
{
        // TODO Auto-generated method stub
if(user_value.length()==0)
{
    Toast.makeText(getBaseContext(), "Please enter a value.", Toast.LENGTH_LONG).show();
}

    SQLiteDatabase aa = openOrCreateDatabase("MLIdata", MODE_WORLD_READABLE, null);
    Cursor c = aa.rawQuery("SELECT CblocationName FROM MLITable WHERE CblocationCode = '"+str+"'", null);
    c.moveToFirst();
    c.getString(c.getColumnIndex("CblocationName"));
    String sas = user_value.getText().toString();
    if(sas==getString(c.getColumnIndex("CblocationName")))
    {
        //here comes the alarm code

        Toast.makeText(getBaseContext(), "till here it has executed.",     Toast.LENGTH_LONG).show();
        Notification notification = new     Notification(android.R.drawable.ic_popup_reminder,
        "My Notification", System.currentTimeMillis());
        notification.defaults |= Notification.DEFAULT_SOUND;
        notification.defaults |= Notification.DEFAULT_VIBRATE;
    }
}


});
}
   }

虽然没有错误，但是当我运行此代码时，当我按下“启动警报”按钮时，它会强制关闭。

我的日志猫如下

我已经尝试了以下链接中提供的所有解决方案，但都无济于事。

Android，找不到字符串资源

需要帮助，

谢谢。

Answer 1

我不知道我的评论会解决您的例外情况。 我将其作为答案，以便您可以关闭此问题。

更改此行：

if(sas==getString(c.getColumnIndex("CblocationName")))

至

if(sas.equals(getString(c.getColumnIndex("CblocationName"))))

如果您不明白为什么应该这样，请继续阅读String比较 。
