android.content.res.Resurces$NotFoundException : String resource ID #0x0 [duplicate]

Question

Please help me, I can't figure out why this error. Just a day ago it worked. I understand the it serches for and id ist'n existing but the id is there in the xml. It give me error here, in onCreate method:

public class DoExamActivity extends Activity {
    private DatabaseHandler db;
    private EditText votoET;
    @Override
    public void onCreate(Bundle savedInstanceState) { 
        super.onCreate(savedInstanceState);
        setContentView(R.layout.do_exam);
        Bundle bundle = getIntent().getExtras();

        db = new DatabaseHandler(getApplicationContext());

        try {
            transcript = new JSONObject(bundle.getString("transcript"));
            exam = new JSONObject(bundle.getString("exam"));
            teacher = new JSONObject(bundle.getString("teacher"));
        } catch (JSONException e) {
            e.printStackTrace();
        }

        votoET = (EditText) findViewById(R.id.examValueET); //here

This is the do_exam.xml of the edit text he cant find. You can see the id is there!

        <TableRow
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:orientation="horizontal" >

            <ImageView
                android:layout_height="30dp"
                android:layout_gravity="left|center_vertical"
                android:layout_weight="1"
                android:background="@color/ios7orange"
                android:contentDescription="@string/textValueDescr"
                android:src="@drawable/rating_star" />

            <TextView
                android:layout_height="50dp"
                android:layout_weight="1" />

            <EditText
                android:id="@+id/examValueET"
                android:layout_height="40dp"
                android:layout_gravity="center_vertical"
                android:layout_marginRight="10dp"
                android:layout_weight="5"
                android:background="@drawable/rounded_edittext"
                android:hint="@string/examValueHint"
                android:inputType="text"
                android:maxLines="1" />
        </TableRow>

Give me this error:

I searched in the R class and the id of that EditText is there and is different from 0. So why this error?

CODE UPDATED

I already cleaned, nothing. The activity it's too big, I added the code until the row of the error. So I used the caps for all the IDs, it worked for two week, now it give me error just on that ET.

Answer 1

My error. I mistaked the rows, the error was from a TextView.setText(int) where I had to set TextView.setText(String.valueOf(int)).

Answer 2

Just as @laalto said:

you're calling essentially setText(0) on your EditText. If you want to set the edittext value to 0, use setText(String) instead of setText(int).

But i assume it's not your fault because the value of int might be dynamic (called from a data source - DB), this was the case for me and i had to box the value of int i.e

instead of

setText(int)

use

setText(String.valueOf(int))

Hope this helps you Or someone! Happy Coding!!!
