I have created 4 buttons in linear layout. This is my xml.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:weightSum="3">
<Button android:id="@+id/button1"
android:layout_weight="1"
android:layout_height="match_parent"
android:layout_width="wrap_content"
android:text="Account"
/>
<Button android:id="@+id/button2"
android:layout_weight="1"
android:layout_height="match_parent"
android:layout_width="wrap_content"
android:text="History"
/>
<Button
android:id="@+id/button3"
android:layout_weight="1"
android:layout_height="match_parent"
android:layout_width="wrap_content"
android:text="Settings"
/>
</LinearLayout>
But above layout adding margins all sides for all 3 buttons. Why is that margins is added by default? How to avoid that?
Try this,it works like you want,
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
>
<Button android:id="@+id/button1"
android:layout_weight="1"
android:layout_height="match_parent"
android:layout_width="match_parent"
android:text="Account"
android:background="#80ffdd10"
/>
<Button android:id="@+id/button2"
android:layout_weight="1"
android:layout_height="match_parent"
android:layout_width="match_parent"
android:background="#800aad10"
android:text="History"
/>
<Button
android:id="@+id/button3"
android:layout_weight="1"
android:layout_height="match_parent"
android:layout_width="match_parent"
android:text="Settings"
android:background="#8c9eff"
/>
</LinearLayout>
In button, set android:layout_width="0dp"
rather than wrap_content
It's because you have given weight
attribute to buttons in horizontal LinearLayout
, each Button
will fill 1/3 of the root layout horizontally. And if you are using a vertical Linear Layout
, you should set android:layout_height="0dp"
Hope this will help you.
These are the shadow by default of Android Button Widget. However If you want to attach one button with another forcefully then add the following properties to each buttons
as per needed
android:layout_marginRight="-5dp"
android:layout_marginLeft="-5dp"
Note : Increase or decrease the value ( Currently -5dp ) of the properties as it suits.
您可以使用自定义背景,它将解决您的问题
android:background="#8c9eff"
