Can I make an Android button template?

Question

I have several buttons in my current app. They are all identical except for their text and a tag. The main.xml would be a lot nicer if I didn\'t have to repeat all the button

Answer 1

Us a style:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <style name="btnlook" >
        <item name="android:id">@+id/button</item>
        <item name="android:layout_width">wrap_content</item>
        <item name="android:layout_height">wrap_content</item>
        <item name="android:padding">10dp</item>
        <item name="android:textColor">@color/button_text</item>
        <item name="android:background">@drawable/grey_blank_48x48</item>
        <item name="android:onClick">onButtonClicked</item>
        <item name="android:typeface">monospace</item>
        <item name="android:textSize">12pt</item>
    </style>
</resources>

and then in your xml layout:

<Button
            style="@style/btnlook"
            android:text="N"
            android:tag="N"/>

Answer 2

The only way to do this to make custom button subclassing the button.

Answer 3

You can make a custom view that extends button and sets all the things that is repeating. Then you can use it as you described, but with a fully qualified name, not just shortname.

class MyButton extends Button {
    public MyButton() {
        // Set the values you want
    }
}

And in XML:

<com.me.myapp.MyButton
    android:text="N"
    android:tag="N" />

Answer 4

You can create a selector

<?xml version="1.0" encoding="UTF-8"?> 
<shape xmlns:android="http://schemas.android.com/apk/res/android" 
     android:shape="rectangle">
    <solid android:color="#AAFFFFFF"/>
    <corners android:bottomRightRadius="7dp"
        android:bottomLeftRadius="7dp" 
        android:topLeftRadius="7dp"
        android:topRightRadius="7dp"/>

And set the 10 button android:background="@drawable/that_selecter"
