Question

我在代码中创建了switch，而不是在xml中。

Switch sw = new Switch(getActivity());
sw.setGravity(Gravity.RIGHT|Gravity.CENTER_VERTICAL);
sw.setTextOn(getString(R.string.ok));
sw.setTextOff(getString(R.string.remove));
sw.setSwitchMinWidth((int) (4.8 * pixels));
sw.setSwitchTypeface(font);
sw.setThumbResource(R.drawable.thumb);

方法setThumbResource工作正常，但setTrackResource方法导致switch的消失。

我的拇指和轨道的xml文件。它们几乎是一样的。

thumb.xml

<?xml version="1.0" encoding="utf-8"?>

    <shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle" >
        <corners
            android:bottomLeftRadius="10dp"
            android:bottomRightRadius="10dp"
            android:topLeftRadius="10dp"
            android:topRightRadius="10dp" />

        <solid android:color="#a79d90" />

    </shape>

track.xml

<?xml version="1.0" encoding="utf-8"?>

    <shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle" >
        <corners
            android:bottomLeftRadius="10dp"
            android:bottomRightRadius="10dp"
            android:topLeftRadius="10dp"
            android:topRightRadius="10dp" />

        <solid android:color="#bfb5a7" />

    </shape>

另外，我想要做的是为TextOn（绿色）和TextOff（红色）设置不同的颜色。我发现只有一种方法 - setTextColor可以改变两种颜色。

您好我已经在此链接上发布了答案，这对我有用。

Switch Track Color

来自那里的代码：

if (isChecked) {
                    mSwtPrivacyView.getTrackDrawable().setColorFilter(ContextCompat.getColor(this, R.color.switch_track_checked_true_color), PorterDuff.Mode.SRC_IN);
                } else {
                    mSwtPrivacyView.getTrackDrawable().setColorFilter(ContextCompat.getColor(this, R.color.switch_track_checked_false_color), PorterDuff.Mode.SRC_IN);
                }

对于@DjimOnDev。我正在使用这个

            Switch sw = new Switch(getActivity());
            sw.setGravity(Gravity.RIGHT|Gravity.CENTER_VERTICAL);
            sw.setTextOn(getString(R.string.ok));
            sw.setTextOff(getString(R.string.remove));

            if (sw.isChecked()) {
                sw.setSwitchTextAppearance(getActivity(), R.style.SwitchTextAppearance1);
            }
            else {
                sw.setSwitchTextAppearance(getActivity(), R.style.SwitchTextAppearance2);
            }

                sw.setSwitchMinWidth((int) (3.6 * pixels));
                sw.setThumbResource(R.drawable.thumb);
                sw.setTrackResource(R.drawable.track);
                sw.setSwitchTypeface(font);

<强> thumb.xml

<?xml version="1.0" encoding="utf-8"?>

    <shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle" >


        <solid android:color="#bfb5a7" />

    </shape>

<强> track.xml

<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_enabled="false" android:drawable="@drawable/thumb_off" /> 
<item                               android:drawable="@drawable/thumb_default" />

<强> styles.xml

<style name="SwitchTextAppearance1">
    <item name="android:textColor">#5db701</item>
</style>

<style name="SwitchTextAppearance2">
    <item name="android:textColor">#ea3d3d</item>
</style>

在代码中设置COnText和Off Text中的开关轨迹可绘制和不同的文本颜色
