How to change checkbox checked color programmatically
提问by user112016322
I'm using the CheckBox view in Android. I would like to change the color of it when its checked. Right now its that default dark green color when its checked and I would like to change it to something different and when not checked, just be the default colors.
我在 Android 中使用 CheckBox 视图。当它被选中时，我想改变它的颜色。现在它是默认的深绿色，当它被选中时，我想把它改成不同的东西，当没有选中时，只是默认颜色。
Here's my code:
这是我的代码：
CheckBox c = new CheckBox(this);
c.setId(View.generateViewId());
c.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
@Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
if(buttonView.isChecked())
{
buttonView.setBackgroundColor(Color.rgb(64, 131, 207));
}
if(!buttonView.isChecked())
{
buttonView.setBackgroundColor(Color.WHITE);
}
}
});
The problem is that it does not change the right thing. Any ideas on how to change this color?
问题是它并没有改变正确的事情。关于如何改变这种颜色的任何想法？

Did you try to create a selectorand assign this selectorto your CheckBoxlike this for example:
您是否尝试创建一个selector并将其分配selector给您CheckBox，例如：
//drawable file called cb_selector
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_checked="true" android:drawable="@drawable/checked" />
<item android:state_checked="false" android:drawable="@drawable/unchecked" />
</selector>
In your layout file apply this file to your checkBox
在您的布局文件中，将此文件应用于您的复选框
<CheckBox
android:id="@+id/myCheckBox"
android:text="My CheckBox"
android:button="@drawable/cb_selector"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
@drawable/checkedand @drawable/uncheckedare two images of your checkbox, so you could put there a color that you want
@drawable/checked和@drawable/unchecked是你的复选框的两幅图像，所以你可以把有颜色要
OR without changing the button layout, with adding this attribute to your checkbox
或不更改按钮布局，将此属性添加到您的复选框
android:buttonTint="@color/YOUR_CHECKMARK_COLOR_HERE"

Replace your CheckBoxwith AppCompatCheckBoxand call following method:
将您替换CheckBox为AppCompatCheckBox并调用以下方法：
public static void setCheckBoxColor(AppCompatCheckBox checkBox, int uncheckedColor, int checkedColor) {
ColorStateList colorStateList = new ColorStateList(
new int[][] {
new int[] { -android.R.attr.state_checked }, // unchecked
new int[] { android.R.attr.state_checked } // checked
},
new int[] {
uncheckedColor,
checkedColor
}
);
checkBox.setSupportButtonTintList(colorStateList);
}

To tint the CompoundButton Tints try this, for Both the API>21 and below.
要为 CompoundButton Tints 着色，请尝试此操作，对于API>21 及以下。
if (Build.VERSION.SDK_INT < 21) {
CompoundButtonCompat.setButtonTintList(button, ColorStateList.valueOf(tintColor));//Use android.support.v4.widget.CompoundButtonCompat when necessary else
} else {
button.setButtonTintList(ColorStateList.valueOf(tintColor));//setButtonTintList is accessible directly on API>19
}

implement this file in res
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_checked="true" android:state_focused="true"
android:drawable="@drawable/checkbox_on_background_focus_yellow" />
<item android:state_checked="false" android:state_focused="true"
android:drawable="@drawable/checkbox_off_background_focus_yellow" />
<item android:state_checked="false"
android:drawable="@drawable/checkbox_off_background" />
<item android:state_checked="true"
android:drawable="@drawable/checkbox_on_background" />
</selector>
and then add button to checkbox
<CheckBox android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="new checkbox"
android:background="@drawable/checkbox_background"
android:button="@drawable/checkbox" />
