TextView   header_text;
header_text = (TextView) findViewById(R.id.header_text1);   
header_text.setSingleLine();

try to use android:gravity="left" or alignParent="left"

To align your Text inside a specific TextView:

    Textview t = (Textview) findViewbyid(R.id.yourView); //refernce to your View
    t.setGravity(Gravity.RIGHT); //or any align you want
    t.setText("String text or long string");
