How to avoid overlap view in relative layout in android?

Question

<ScrollView 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:orientation="vertical" >

<RelativeLayout
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" >

    <TextView
        android:id="@+id/textView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true"
        android:layout_alignParentLeft="true"
        android:textSize="30sp" />

    <TextView
        android:id="@+id/textView2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@id/textView1"
        android:textSize="20sp" />

    <TextView
        android:id="@+id/textView3"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@id/textView2"
        android:textSize="20sp" />

    <TextView
        android:id="@+id/textView4"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@id/textView3"
        android:textSize="20sp" />

    <TextView
        android:id="@+id/textView5"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@id/textView4"
        android:textSize="20sp" />

    <TextView
        android:id="@+id/textView6"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@id/textView5"
        android:textSize="20sp" />

    <TextView
        android:id="@+id/textView7"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@id/textView6"
        android:textSize="20sp" />

    <TextView
        android:id="@+id/textView8"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@id/textView7"
        android:textSize="20sp" />

    <TextView
        android:id="@+id/textView9"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@id/textView8"
        android:textSize="20sp" />

    <Button
        android:id="@+id/button1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@id/textView9" />

    <TextView
        android:id="@+id/textView10"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="商店圖片:"
        android:textSize="15sp"
        android:layout_alignParentTop="true"
        android:layout_alignLeft="@id/imageView1" />

    <ImageView
        android:id="@+id/imageView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentRight="true"
        android:layout_below="@id/textView10"
        android:contentDescription="@string/top" />
</RelativeLayout>

Simple output:
textview1     textview9
textview2     imageview1
.
.
.
button1

The above layout is a page that divide horizitonally, for the left side , there is a list of textview and button , for the right side, there is an image view. The problem is: when the textview content is too long, the imageview will overlap the content of it, besides using bringtofront(), are there any way (in xml ) to resize the width of the text view if it overlap with image view?

Answer 1

Use layout_toStartOf in the first item with second item +id under double quotes

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="horizontal" >

    <TextView
        android:id="@+id/email"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_centerVertical="true"
        android:layout_toStartOf="@+id/selectaccount"
        android:text="very long text which used to overlap over radio button"
        android:textAppearance="?android:attr/textAppearanceMedium" />

    <RadioButton
        android:id="@+id/selectaccount"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentRight="true"
        android:layout_centerVertical="true" />

</RelativeLayout>

note this argument in textview

android:layout_toStartOf="@+id/selectaccount"

An XML is read from top to bottom

so this is how the Layout is rendered in Android

• android:layout_toStartOf="@id/item means that item is defined above this line
• android:layout_toStartOf="@+id/item means that item will appear later somewhere below this line
