Use values ​​from strings.xml

  • 772

I have this code in the string.xml

<?xml version="1.0" encoding="utf-8"?>
    <resources>
         <string name="hint_input_user_es">EMAIL:</string>
    </resources>

And what I want is to get "EMAIL" and display it in a textView as Hint. I have tried it in several ways and with all of them I get the same error.

TextView login_email = (TextView) findViewById(R.id.login_email);

1. login_email.setHint(getText(R.string.hint_input_user_es));
2. login_email.setHint(getResources().getString(R.string.hint_input_user_es));
3. login_email.setHint(getString(R.string.hint_input_user_es));

And in all cases I get this error:

android.content.res.Resources$NotFoundException: String resource ID #0x7f05002b

Thank you so much.

    I managed to test this code and it works correctly

    TextView hint = (TextView) findViewById(R.id.textView2);
String hint2 = getResources().getString(R.string.hint2);
hint.setHint(hint2);

<resources>
    <string name="hint2">HINT2</string>
</resources>

    But it seems to me that the TextView, even if it has a Hint field, does not apply for that information to be displayed on the screen.

    <TextView
    android:id="@+id/textView"
    android:hint="@string/hint"
    android:text="TextView"/>

    Perhaps you may have thought more of an EditText? Since in the EditText when there is nothing written, it shows the Hint

     <EditText
     android:id="@+id/editText"
     android:layout_width="wrap_content"
     android:layout_height="wrap_content"
     android:hint="@string/hint"/>

    Note: I tried the same code with an EditText and it works too

  2. The value of the "hint" or text can be set programmatically without any problem :

    myEditText.setHint("Escribe algo!");

    or directly in sight.

     <EditText
     android:id="@+id/editText"
     android:layout_width="wrap_content"
     android:layout_height="wrap_content"
     android:hint="Escribe algo!"/>

    Regarding the bug:

    android.content.res.Resources$NotFoundException: String resource ID #0x7f05002b

    at some point in your code you are assigning either the setHint() or setText() method an integer value, you can test yourself to see what I'm saying.

    I add a similar answer:

    Error android.content.res.Resources$NotFoundException: String resource ID #0xbb8 on Android
