我希望文本视图能覆盖整个屏幕

Question

I want my TextView to Cover the whole screen in a instance and override all the components in that XML file. How can I do this?

I have tried by setting fill_parent to both android:layout_width and android:layout_height but it does not work.

Answer 1

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity" >

    <TextView
        android:id="@+id/textView1"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_alignParentBottom="true"
        android:layout_centerHorizontal="true"
        android:layout_marginBottom="fill_parent"
        android:text="TextView" />

</RelativeLayout>

It's likely that you have padding set in the parent. match_parent is a little more modern :)
