Question

我尝试使用以下内容制作xml选择器：

backgroundDrawable

当我尝试将checkBox设置为CheckBox时，复选框也不会替换shuffle.setBackground(android.support.v4.content.res.ResourcesCompat.getDrawable(getResources(), R.drawable.shuffle, null));样式：

button drawable

关注此问题：Change icons of checked and unchecked for Checkbox for Android我需要将android:button="@drawable/checkbox"设置为我的xml：CheckBox，但我无法执行此操作，因为我正在以编程方式创建Shader "Custom/NoobShader_03" { Properties { _Color ("Color", Color) = (1,1,1,1) _Scale ("Wave Scale", float) = 0.6 _Frequency ("Frequency", float) = 1 _Speed ("Speed", float) = 0.5 _Scale2 ("Wave Scale", float) = 0.6 _Frequency2 ("Frequency", float) = 1 _Speed2 ("Speed", float) = 1 } SubShader { Pass{ Tags { "LightMode" = "ForwardBase"} CGPROGRAM #pragma vertex vert #pragma fragment frag float4 _Color; float _Scale; float _Frequency; float _Speed; float _Scale2; float _Frequency2; float _Speed2; float4 _LightColor0; struct VertexOutput { float4 pos : SV_POSITION; float3 nor : NORMAL; float4 col : COLOR; }; struct VertexInput { float4 vertex : POSITION; float3 normal : NORMAL; }; struct FragmentOutput { float4 color : COLOR; }; VertexOutput vert (VertexInput i) { VertexOutput VOUT; float randomNum = 1 / _Time; float newPos = _Scale * sin(_Time.w * _Speed + i.vertex.x * _Frequency); float newPos2 = _Scale2 * cos(_Time.w * _Speed2 + i.vertex.z * _Frequency2); //i.vertex.y += newPos; float4 tempPos = i.vertex; tempPos.y += newPos * newPos2; VOUT.pos = mul(UNITY_MATRIX_MVP,tempPos); VOUT.nor = float3(mul(UNITY_MATRIX_MVP,tempPos).xyz); float3 normalDirection = normalize( mul( float4( VOUT.nor, 0.0 ), _World2Object).xyz); float3 lightDirection; float atten = 1.0; lightDirection = normalize(_WorldSpaceLightPos0.xyz); float3 diffuseRefflection = atten * _LightColor0.xyz * _Color.rgb * max( 0.0, dot(normalDirection, lightDirection)); VOUT.col = float4(diffuseRefflection, 0.0); return VOUT; } FragmentOutput frag(VertexOutput v) { FragmentOutput FOUT; FOUT.color = v.col + _Color; return FOUT; } ENDCG } } FallBack "Diffuse" } 。有没有办法如何实现这个目标？

简单方法

在drawable文件夹中创建一个新布局并将其命名为custom_checkbox（您也可以重命名）

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

在布局活动

中使用此功能

<CheckBox
android:id="@+id/checkbox"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:button="@drawable/custom_checkbox"/>

Answer 2

使用下面的代码行，我认为它会起作用

yourcheckbox.setButtonDrawable(yourdrawable);

Answer 3

use this 

shuffle.setButtonDrawable(R.drawable.custom_checkbox_selector);



<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">

    <item android:drawable="@drawable/radiobutton_checked" android:state_checked="true"/>
    <item android:drawable="@drawable/radiobutton_unchecked" android:state_checked="false"/>

</selector>

Answer 4

这对我有用：

<android.support.v7.widget.AppCompatCheckBox
android:id="@+id/checkbox"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="@drawable/custom_checkbox"
android:button="@null"/>

Answer 5

如果您使用的是sdk 28（androidx）及更高版本，请尝试使用

androidx.appcompat.widget.AppCompatCheckBox

代替

Checkbox

Answer 6

drawable / checkbox_custome.xml

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

Android用自定义drawable选择器替换复选框样式
