如何自定义切换按钮？

Question

我期待自定义Switch按钮变为如下:

怎么做到这一点？

Answer 1

然而,这可能不是最好的方法,但我采取了不同的方式来解决我的所有Switch相关问题.这是我的代码 -

<RadioGroup
        android:checkedButton="@+id/offer"
        android:id="@+id/toggle"
        android:layout_width="match_parent"
        android:layout_height="30dp"
        android:layout_marginBottom="@dimen/margin_medium"
        android:layout_marginLeft="50dp"
        android:layout_marginRight="50dp"
        android:layout_marginTop="@dimen/margin_medium"
        android:background="@drawable/pink_out_line"
        android:orientation="horizontal">

        <RadioButton
            android:layout_marginTop="1dp"
            android:layout_marginBottom="1dp"
            android:layout_marginLeft="1dp"
            android:id="@+id/search"
            android:background="@drawable/toggle_widget_background"
            android:layout_width="0dp"
            android:layout_height="match_parent"
            android:layout_weight="1"
            android:button="@null"
            android:gravity="center"
            android:text="Search"
            android:textColor="@color/white" />

        <RadioButton
            android:layout_marginRight="1dp"
            android:layout_marginTop="1dp"
            android:layout_marginBottom="1dp"
            android:id="@+id/offer"
            android:layout_width="0dp"
            android:layout_height="match_parent"
            android:layout_weight="1"
            android:background="@drawable/toggle_widget_background"
            android:button="@null"
            android:gravity="center"
            android:text="Offers"
            android:textColor="@color/white" />
    </RadioGroup>

pink_out_line.xml

<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">
    <corners android:radius="2dp" />
    <solid android:color="#80000000" />
    <stroke
        android:width="1dp"
        android:color="@color/pink" />
</shape>

toggle_widget_background.xml

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@color/pink" android:state_checked="true" />
    <item android:drawable="@color/dark_pink" android:state_pressed="true" />
    <item android:drawable="@color/transparent" />
</selector>

这是输出 -

它是一个简单的 xml 设计。它看起来像 iOS 开关，检查下图

您需要创建 custom_thumb.xml 和 custom_track.xml

这是我的开关，我需要一个非常大的开关，所以添加了 layout_width/layout_height 参数

 <androidx.appcompat.widget.SwitchCompat
        android:id="@+id/swOnOff"
        android:layout_width="@dimen/_200sdp"
        android:layout_marginStart="@dimen/_50sdp"
        android:layout_marginEnd="@dimen/_50sdp"
        android:layout_marginTop="@dimen/_30sdp"
        android:layout_gravity="center"
        app:showText="true"
        android:textSize="@dimen/_20ssp"
        android:fontFamily="@font/opensans_bold"
        app:track="@drawable/custom_track"
        android:thumb="@drawable/custom_thumb"
        android:layout_height="@dimen/_120sdp"/>

现在创建 custom_thumb.xml

<?xml version="1.0" encoding="utf-8"?>
<selector
    xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_checked="false">
        <shape android:shape="oval">
            <solid android:color="#ffffff"/>
            <size android:width="@dimen/_100sdp"
                android:height="@dimen/_100sdp"/>
            <stroke android:width="1dp"
                android:color="#8c8c8c"/>
        </shape>
    </item>
    <item android:state_checked="true">
        <shape android:shape="oval">
            <solid android:color="#ffffff"/>
            <size android:width="@dimen/_100sdp"
                android:height="@dimen/_100sdp"/>
            <stroke android:width="1dp"
                android:color="#34c759"/>
        </shape>
    </item>
</selector>

现在创建 custom_track.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_checked="false">
        <shape android:shape="rectangle">
            <corners android:radius="@dimen/_100sdp" />
            <solid android:color="#ffffff" />
            <stroke android:color="#8c8c8c" android:width="1dp"/>
            <size android:height="20dp" />
        </shape>
    </item>
    <item android:state_checked="true">
        <shape android:shape="rectangle">
            <corners android:radius="@dimen/_100sdp" />
            <solid android:color="#34c759" />
            <stroke android:color="#8c8c8c" android:width="1dp"/>
            <size android:height="20dp" />
        </shape>
    </item>
</selector>

Answer 3

您可以使用以下代码更改颜色和文本:

<org.jraf.android.backport.switchwidget.Switch
                        android:id="@+id/th"
                        android:layout_width="match_parent"
                        android:layout_height="wrap_content"
                        app:thumb="@drawable/apptheme_switch_inner_holo_light"
                        app:track="@drawable/apptheme_switch_track_holo_light"
                        app:textOn="@string/switch_yes"
                        app:textOff="@string/switch_no"
                        android:textColor="#000000"
                        />

在res/values文件夹中创建名为colors.xml的xml:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <color name="red">#ff0000</color>
    <color name="green">#00ff00</color>
</resources>

在drawable文件夹中,创建一个xml文件my_btn_toggle.xml:

  <selector xmlns:android="http://schemas.android.com/apk/res/android">
        <item android:state_checked="false" android:drawable="@color/red"  />
        <item android:state_checked="true" android:drawable="@color/green"  />
    </selector>

并在定义切换按钮的xml部分中添加:

android:background="@drawable/my_btn_toggle

改变颜色textOn和textOff使用

android:switchTextAppearance="@style/Switch"

Answer 4

<Switch android:layout_width="wrap_content" 
                    android:layout_height="wrap_content"
                    android:thumb="@drawable/custom_switch_inner_holo_light"
                    android:track="@drawable/custom_switch_track_holo_light"
                    android:textOn="@string/yes"
                    android:textOff="@string/no"/>

绘制/ custom_switch_inner_holo_light.xml

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_enabled="false" android:drawable="@drawable/custom_switch_thumb_disabled_holo_light" />
    <item android:state_pressed="true"  android:drawable="@drawable/custom_switch_thumb_pressed_holo_light" />
    <item android:state_checked="true"  android:drawable="@drawable/custom_switch_thumb_activated_holo_light" />
    <item                               android:drawable="@drawable/custom_switch_thumb_holo_light" />
</selector>

绘制/ custom_switch_track_holo_light.xml

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_focused="true"  android:drawable="@drawable/custom_switch_bg_focused_holo_light" />
    <item                               android:drawable="@drawable/custom_switch_bg_holo_light" />
</selector>

下一个图像是9.paths drawables,它们必须是不同的密度(mdpi,hdpi,xhdpi,xxhdpi).例如,我给xxhdpi(你可以根据需要调整大小):

绘制/ custom_switch_thumb_disabled_holo_light

绘制/ custom_switch_thumb_pressed_holo_light

绘制/ custom_switch_thumb_activated_holo_light

绘制/ custom_switch_thumb_holo_light

绘制/ custom_switch_bg_focused_holo_light

绘制/ custom_switch_bg_holo_light

Answer 5

使用下面的代码创建一个自定义开关按钮，如下所示。

<androidx.appcompat.widget.SwitchCompat
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/customSwitch"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintRight_toRightOf="parent"
        app:layout_constraintTop_toTopOf="parent"
        android:checked="false"
        app:track="@drawable/track"
        android:thumb="@drawable/thumb"
        android:text="" />

</vector>

Answer 6

我做到了这一点

通过做:

1)自定义选择器:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@drawable/ic_switch_off"
          android:state_checked="false"/>
    <item android:drawable="@drawable/ic_switch_on"
          android:state_checked="true"/>
</selector>

2)使用v7 SwitchCompat

<android.support.v7.widget.SwitchCompat
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:background="@null"
    android:button="@drawable/checkbox_yura"
    android:thumb="@null"
    app:track="@null"/>

Answer 7

我使用这种方法创建一个自定义开关使用RadioGroup和RadioButton;

您可以使用 Android 材料组件。

构建.gradle：

implementation 'com.google.android.material:material:1.0.0'

布局.xml：

<com.google.android.material.button.MaterialButtonToggleGroup
        android:id="@+id/toggleGroup"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:checkedButton="@id/btn_one_way"
        app:singleSelection="true">

    <Button
            style="@style/Widget.MaterialComponents.Button.OutlinedButton"
            android:id="@+id/btn_one_way"
            android:layout_width="0dp"
            android:layout_weight="1"
            android:layout_height="wrap_content"
            android:text="One way trip" />

    <Button
            style="@style/Widget.MaterialComponents.Button.OutlinedButton"
            android:id="@+id/btn_round"
            android:layout_width="0dp"
            android:layout_weight="1"
            android:layout_height="wrap_content"
            android:text="Round trip" />

</com.google.android.material.button.MaterialButtonToggleGroup>

您可以使用常规的Switch小部件,只需调用setTextOn()和setTextOff(),或使用android:textOn和android:textOff属性.
