线性布局将元素向右对齐

Question

I have a linear layout that i use for a list view with a custom adapter, it consists in an image and two text views. My problem is that the first text view length is not always the same so i dont know how to align every second text view to the same position.

row.xml

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

<ImageView
    android:id="@+id/imageView1"
    android:layout_gravity="center"
    android:layout_width="48dp"
    android:layout_margin="5dp"
    android:layout_height="48dp"
    android:src="@drawable/ic_launcher" />

<TextView
    android:id="@+id/textView1"
    android:layout_gravity="center"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:textSize="25dp"
    android:text="TextView" />
<TextView
    android:id="@+id/textView2"
    android:layout_gravity="center"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:textColor="@color/txtresultadocolor"
    android:textSize="25dp"
    android:layout_marginLeft="15dp"
     />

This is my code now but the second text view always changes. I would appreciate any help.

Answer 1

You can give android:layout_weight="0.3" to the first TextView , which will make the second TextView be attached to one position and the size of the first TextView will increase according to the length of the text.

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

<ImageView
    android:id="@+id/imageView1"
    android:layout_width="48dp"
    android:layout_height="48dp"
    android:layout_gravity="center"
    android:layout_margin="5dp"
    android:src="@drawable/ic_launcher" />

<TextView
    android:id="@+id/textView1"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_gravity="center"
    android:layout_weight="0.3"
    android:text="TextViewd1391381231283123100"
    android:textSize="25dp" />

<TextView
    android:id="@+id/textView2"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="center"
    android:layout_marginLeft="15dp"
    android:text="adfafasdfs"
    android:textColor="@color/Red"
    android:textSize="25dp" />

Answer 2

I guess the issue here is android:layout_gravity="center". The textviews are getting displayed center aligned and the display length will vary as per their text sizes and they will not be aligned to the same position.

Once you remove it and add android:layout_marginLeft="15dp" to the first textview also both textviews should become aligned to the same position in the left.

要将视图右对齐，请使用android:layout_gravity="right" 。
