Menu
My layout have ImageView(iv) and TextView(tv). I want to let the tv right of iv. And the tv's height is same as iv's. The tv Gravity set as CENTER_VERTICAL.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/RelativeLayout1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<ImageView
android:id="@+id/iv"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"/>
<TextView
android:id="@+id/tv"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_toRightOf="@+id/iv"
android:text="TextView" android:gravity="center_vertical"/>
</RelativeLayout>
How to arrive the goal?

If in linearlayout your orientation vertical, you can put the textview in the "horizontal center" by android:layout_gravity="center" . For centering textview vertically you need to set layout_height of textview to match_parent and set android:gravity to "center".
android:scaleType. Controls how the image should be resized or moved to match the size of this ImageView. android:src. Sets a drawable as the content of this ImageView.
Using clickable imagesYou can turn any View , such as an ImageView , into a button by adding the android:onClick attribute in the XML layout. The image for the ImageView must already be stored in the drawable folder of your project.
For adding an image from Android Studio, Drag the ImageView widget to the activity area of the application, a pop-up dialogue box will open choose from the wide range of drawable resources and click “OK“.
hi try this .....
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/RelativeLayout1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<ImageView
android:id="@+id/iv"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:src="@drawable/ic_title_home_demo" />
<TextView
android:id="@+id/tv"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignBottom="@+id/iv"
android:layout_alignTop="@+id/iv"
android:layout_toRightOf="@+id/iv"
android:gravity="center_vertical"
android:text="TextView" />
</RelativeLayout>
You have to set the textview property to android:layout_alignTop="@id/iv" and android:layout_alignBottom="@id/iv"
