Why is my Button's text cut-off?

Question

I got a normal button, but the text is cut-off. I don't know why it's happening.

Can anybody analyze why it happened?

Code:

<TextView
        android:id="@+id/txt_project_title"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"

android:padding

Answer 2

Problem may be with android:layout_weight you are using..Its mainly used for controll/distribute the space within the view.
