How to right-align text in an Android TextView or EditText?

I have an EditText in my application. I want to align the text in it to the right instead of the default left. I tried adding

android:layout_gravity="right"

but this doesn't seem to work. any other开发者_StackOverflow中文版 suggestions please?

You should use android:gravity="right". layout_gravity is for the view (EditText) alignment against the container.

You may use android:layout_alignParentRight="true" to align the EditText's right edge to its parent's right edge. Also, if you really want to use the layout_gravity or gravity attributes, check out this article that discusses the proper use of them.

You can jst set property for edit text in property window i.e. Gravity to right or by adding code of lin e in xml file of UI : android:gravity="right"

layout_gravity means that you are specifying the layouts attribute, not the element inside. In some conditions, such as layout_width and layout_height is wrap_content, layout specifications can give what you want about the element inisde your layout, since the boundries of the layout and the element (not elements) are the same..

use layout width and height as wrap content inside relative layout :

<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="wrap_content">

    <ImageView
        android:id="@+id/icon"
        android:layout_width="64dp"
        android:layout_height="64dp"
        android:layout_alignParentStart="true"
        android:paddingEnd="16dp"
        android:paddingStart="8dp"
        tools:src="@mipmap/ic_launcher"
        android:layout_alignParentLeft="true"
        android:paddingRight="16dp"
        android:paddingLeft="8dp"
        android:contentDescription="@string/todo" />

    <TextView
        android:id="@+id/title"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_toEndOf="@id/icon"
        android:maxLines="1"
        android:lines="1"
        android:paddingTop="8dp"
        tools:text="Google"
        android:layout_toRightOf="@id/icon" />

    <TextView
        android:id="@+id/last_used"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentRight="true"
        android:layout_alignParentTop="true"
        android:paddingTop="8dp"
        tools:text="Last used: yesterday at 18.54" />
</RelativeLayout>
