Save Button | note application

Issue

I'm having trouble adding a Button to save text input in my editorActivity class, which is an Activity I designated to view, edit, and save a note item.

The class uses the back button (hardware) and app launcher icon to save the key/value pair to a SharedPreferences object. I want to add a Button that will do the same.

I get an error in the console stating:

res\layout\activity_note_editor.xml:18: error: Error: No resource found that matches the given name (at 'text' with value '@string/Save').

I'm not sure what this implies. And would appreciate some guidance as to where I should to fix this error.

This is what I have so far:

private NoteItem note;


@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_note_editor);                  // Load custom note edit layout
    getSupportActionBar().setDisplayHomeAsUpEnabled(true);          // Launcher icon becomes an options button = home

    Intent intent = this.getIntent();           // Reference to intent object in first activity
    note = new NoteItem();
    note.setKey(intent.getStringExtra("key"));  // retrieve key and saved in note object
    note.setText(intent.getStringExtra("text"));    // Retrieve text and save in note object

    EditText et = (EditText) findViewById(R.id.noteText);
    et.setText(note.getText());
    et.setSelection(note.getText().length());
}

private void saveAndFinish() {
    EditText et = (EditText) findViewById(R.id.noteText);
    String noteText = et.getText().toString();

    Intent intent = new Intent();
    intent.putExtra("key", note.getKey());      
    intent.putExtra("text", noteText);  
    setResult(RESULT_OK, intent);
    finish();
}

@Override                   // launcher icon sends data back to main activity
public boolean onOptionsItemSelected(MenuItem item) {
    if (item.getItemId() == android.R.id.home) {            
        saveAndFinish();
    }
    return false;                                           
}

@Override                       // device back button sends data back to main activity
public void onBackPressed() {
    saveAndFinish();
}

public void addListenerOnButton(){

    Button button = (Button) findViewById(R.id.save);

    button.setOnClickListener(new View.OnClickListener() {
        public void onClick(View view) {
            saveAndFinish();
        }
    });

}
}

Solution

I'm not sure what this implies.

It implies that you don't have a resource in your strings.xml with the identifier of "Save"

When you use @String, or @anyAndroidResource for that matter, it looks in the corresponding file. So @drawable would look inside the drawables folder for whatever identifier you used.

In values/strings.xml you should have something like

<string name="Save">Save</string>
