如何以编程方式更改复选框选中的颜色

问题描述

我在 Android 中使用 CheckBox 视图.当它被选中时，我想改变它的颜色.现在它是选中时的默认深绿色，我想将其更改为不同的颜色，如果未选中，则为默认颜色.

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.

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);
        }

    }
});

问题在于它并没有改变正确的事情.关于如何更改此颜色的任何想法?

The problem is that it does not change the right thing. Any ideas on how to change this color?

推荐答案

您是否尝试创建 selector 并将此 selector 分配给您的 CheckBox像这样例如:

Did you try to create a selector and assign this selector to your CheckBox like this for example:

//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>

在您的布局文件中将此文件应用到您的复选框

In your layout file apply this file to your checkBox

<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/checked 和 @drawable/unchecked 是你的复选框的两张图片，所以你可以在那里放一个你想要的颜色

@drawable/checked and @drawable/unchecked are two images of your checkbox, so you could put there a color that you want

或不改变按钮布局，将此属性添加到您的复选框

OR without changing the button layout, with adding this attribute to your checkbox

android:buttonTint="@color/YOUR_CHECKMARK_COLOR_HERE"
