如何在Android中设置按钮选择颜色以及圆角?

问题描述

我想在android中为按钮设置圆角，并在选择时更改按钮颜色.我正在做以下事情.

I want to set a rounded corner for a button in android along with changing the button color on when selected. I am doing the following things.

drawable/push_button.xml

drawable/push_button.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
    <item android:state_pressed="true"  android:drawable="@color/green"/>
    <item android:state_focused="true"  android:drawable="@color/green"/>
    <item android:state_focused="false"  android:drawable="@color/green"/>
    <item android:state_pressed="false" android:drawable="@color/red"/>
    <item  android:drawable="@drawable/push_button_background"/>
</selector>

drawable/push_button_background.xml

drawable/push_button_background.xml

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    >
    <solid android:color="#3F4040"/>
    <corners
    android:radius="7dp"
    />
</shape>

在代码中，我正在使用

android:background="@drawable/push_button"

在这里，问题是，在选择&时，按钮的颜色设置正确.取消选择.但是，圆角不起作用.

Here, the problem is, button colors are setting properly when selected & deselected. But, rounded corners are not working.

该怎么做?如果我使用

How to do that?If I use

android:background="@drawable/push_button_background"

然后，圆角起作用了，但是选择时按钮颜色的改变不起作用

then, rounded corners are working but the button color change on selection is not working

如何实现呢?
