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

If you are using this kind of design than you should use linear Layout. and use Table Rows in it to display this kind of view.

and also use weight so that your view doesn't et overlap on other views. try like this:

<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" >

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical" >
<TableRow 
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:gravity="center"
    android:weightSum="10">
    <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"
        android:text="test"
        android:layout_weight="5" />

    <TextView
        android:id="@+id/textView2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@id/textView1"
        android:textSize="20sp" 
        android:text="test"
        android:layout_weight="5"/>
</TableRow>

</LinearLayout>
</ScrollView>

Hope it Helps!!

Answer 2

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

Answer 3

Align the all the textviews to leftOf imageview like lastone : android:layout_toLeftOf="@id/imageView1"

Answer 4

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:weightSum="1.0" >

<LinearLayout
    android:layout_width="0dp"
    android:layout_height="match_parent"
    android:layout_weight=".5"
    android:orientation="vertical" >

    <TextView
        android:id="@+id/textView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Large Text"
         />

    <TextView
        android:id="@+id/textView2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Medium Text"
        />

    <TextView
        android:id="@+id/textView3"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Medium Text"
        />

</LinearLayout>

<LinearLayout
    android:layout_width="0dp"
    android:layout_height="match_parent"
    android:layout_weight=".5"
    android:orientation="vertical" >

    <ImageView
        android:id="@+id/imageView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/ic_launcher" />

</LinearLayout>

Answer 5

I had a similar problem and tried pretty much everything suggested here and in other similar threads.

The one additional thing that did it for me was to add:

android:layout_toStartOf="@+id/youroverlappeditem"

so the overlapping item will only run up to the overlapped item.

layout_toLeftOf was not enough on its own

and of course ellipsize="end" was needed as appropriate.

Mine was for a recyclerview with a relative layout.

Answer 6

You can overcome that issue by clicking on "infer constraints". Follow the picture which will show the way:

Answer 7

Try constraint layout. It simplifies your layout.

Answer 8

Add this line one your xml layout

tools:ignore="RelativeOverlap"
