android.content.res.Resurces $ NotFoundException:字符串资源ID#0x0

Question

请帮帮我,我无法弄清楚为什么会出现这个错误.就在一天前,它奏效了.我理解它的serches和id ist'n存在,但id在xml中.它在这里给我错误,onCreate方法:

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

这是do_exam.xml他无法找到的编辑文本.你可以看到id在那里!

        <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>

给我这个错误:

我在R类中搜索并且它的id在EditText那里并且与0不同.那么为什么会出现这个错误呢？

代码更新

我已经清理过,没事.活动太大了,我把代码添加到错误行.所以我使用大写的所有ID,它工作了两个星期,现在它只给我错误的ET.

Answer 1

我的错误.我错了行,错误来自TextView.setText(int)我必须设置的地方TextView.setText(String.valueOf(int)).

Answer 2

正如@laalto所说:

你在EditText上调用的基本上是setText(0).如果要将edittext值设置为0,请使用setText(String)而不是setText(int).

但我认为这不是你的错,因为int的值可能是动态的(从数据源 - 数据源调用),这就是我的情况,我不得不将int的值设为ie

代替

setText(int)

使用

setText(String.valueOf(int))

希望这可以帮助你或某人!快乐的编码!!!
