Android relative layout center vertical with margin

Question

in Android's RelativeLayout we can set textView exact in the center of the screen with this code:

<TextView
    android:text="This is TextView"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_centerVertical="true"
    android:layout_centerHorizontal="true" />

result:

top
-
-
-
-
This is TextView (center vertical)
-
-
-
-
bottom

But I need the textView to be a little bit to the bottom, I try add marginTop but seems like after using layout_centerVertical=true its become impossible. Any solution?

Expected result (a little bit to bottom):

top
-
-
-
-
-
-
This is TextView (center vertical slight to bottom)
-
-
bottom

Try this:

Try to use RelativeLayout which can easily done your requirement using weight :

<RelativeLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:gravity="center_vertical">
      <TextView
          android:id="@id/dummy"
          android:layout_width="wrap_content"
          android:layout_height="wrap_content"
          android:layout_centerVertical="true"
          android:layout_centerHorizontal="true" />
      <TextView
          android:layout_below="@id/dummy"
          android:layout_marginTop="10dp"
          android:text="This is TextView"
          android:layout_width="wrap_content"
          android:layout_height="wrap_content"/>
</RelativeLayout>

Answer 2

Try to use LinearLayout which can easily done your requirement using weight :

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1">

    </LinearLayout>
    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1"
        android:gravity="center_vertical">
        <TextView
            android:text="This is TextView"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"/>
    </LinearLayout>
</LinearLayout>

Why should add nested view inside parent view ?

Use paddingTop attribute.

Example:

<RelativeLayout
    android:id="@+id/rlParentView"
    android:layout_width="match_parent"
    android:layout_height="wrap_content">


    <ImageView
        android:id="@+id/imageView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerVertical="true"
        android:paddingTop="10dp"/>

</RelativeLayout>

Hope this will help you.

I encountered this kind of problem today and I figured out this way. Sapce and LinearLayout is a good solution to do this.

<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"
    android:background="@color/base_background_color">

    <android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="@color/base_toolbar_color"
        android:minHeight="?attr/actionBarSize"/>

    <android.support.v7.widget.RecyclerView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_below="@+id/toolbar"/>

    <!-- using LinearLayout to align ProgressBar to center vertical -->
    <LinearLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerHorizontal="true"
        android:layout_centerVertical="true"
        android:orientation="vertical">

        <Space
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"/>

        <ProgressBar
            android:id="@+id/other_profile_progressBar"
            style="?android:attr/progressBarStyleLarge"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:indeterminate="false"/>
    </LinearLayout>
</RelativeLayout>

如果你不打算为视图制作翻译动画，你可以使用android:translationY属性按你想要的方式推送它（推高的负值）
