Question

I have a widget and an activity, when I start the activity, I have to read text from the TextView of the widget and show it in the TextWidget of the activity.

My relevant code:

 String frase=""; 
 TextView text_frase = (TextView) findViewById(R.id.widget_textview_frase);
 if (text_frase != null){
    frase = (String) text_frase.getText();
 }
 Log.v(LOG_CLASS_NAME, "frase: "+frase);

debugging it – I have text_frase as null (I think I can’t reference to a view object from another view.) Anyway, how could I do this?

Answer 1

No, you can’t. I suggest one of this ways:

1. Adding your text to a Bundle and fetching it in your activity.

in your widget:

Intent intent = new Intent(context, YourActivity.class);
Bundle b= new Bundle();
b.putString("Text", yourtext);
intent.putExtras(b);
PendingIntent pendingIntent = PendingIntent.getActivity(context, appWidgetId, intent, PendingIntent.FLAG_CANCEL_CURRENT);

in your activity:

Intent intent=getIntent();
Bundle b= intent.getExtras();
String text= b.getString("Text", "");

2. Using SharedPreferences for saving your text and loading it in the activity.

In your situation, I recommend method 1.
