android display string

Question

I am trying to pass a string from one activity to another. I retrieved the information like this:

Intent openReadMail = getIntent();
String readfrom = openReadMail.getStringExtra("from");

Now I want to display this string on screen. I this xml TextView element:

 <TextView
        android:id="@+id/from"
        android:layout_width="match_parent"/>

but I can't convert the string to a textview, is there a better way of doing this? thanks for your help guys!

One observation, your TextView should have a layout_height="" attribute as well, otherwise you may get an exception. — Andy Res

You have to create a variable for your TextView and then set the text.

TextView fromtxt = (TextView) findViewById(R.Id.from);

Fromtxt.setText(readfrom);

You need to set the text of the TextView with the String you read in.

TextView tv = (TextView)findViewById(R.id.from);
tv.setText(readFrom);
