android - 如何在android中设置按钮样式

Question

普通按钮的样子:

现在，请告诉我，我怎样才能制作一个与附加图像按钮相同的简单按钮(即按钮角形状是圆形的，两个按钮之间也没有间隙)

Answer 1

1- 为按下和释放状态创建形状(具有所需颜色)

要创建形状，我建议您使用这个很棒的网站:http://angrytools.com/android/button/

drawable\botton_shape_pressed.xml:

<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">
    <gradient
        android:startColor="@color/pressed_button_background"
        android:endColor="@color/pressed_button_background"
        android:angle="45"/>
    <padding android:left="7dp"
        android:top="7dp"
        android:right="7dp"
        android:bottom="7dp" />
    <corners android:radius="8dp" />
</shape>

drawable\botton_shape_released.xml:

<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">
    <gradient
        android:startColor="@color/released_button_background"
        android:endColor="@color/released_button_background"
        android:angle="45"/>
    <padding android:left="7dp"
        android:top="7dp"
        android:right="7dp"
        android:bottom="7dp" />
    <corners android:radius="8dp" />
</shape>

2- 为两个形状创建一个选择器

可绘制\botton_selector.xml:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@drawable/botton_shape_pressed"
          android:state_pressed="true" />
    <item android:drawable="@drawable/botton_shape_pressed"
          android:state_selected="true" />
    <item android:drawable="@drawable/botton_shape_released" />
</selector>

3- 使用按钮的选择器

<Button
    android:id="@+id/button1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="@string/test"
    android:textColor="@color/blue_text"
    android:onClick="testOnClickListener"
    android:background="@drawable/botton_selector" />
