RadioButton sets selector color and picture selector

     When using RadioButton today, I encountered the problem that the button setting color and the picture selector were invalid. In fact, it is the problem of state_checked. I remember that it is possible to use state_selected when using button before. I don’t know why RadioButton can’t. Jot it down today before everyone else makes the same mistake!

1. First look at the selector file, which is the picture

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@drawable/main_3d_green" android:state_checked="true" />
    <item android:drawable="@drawable/main_3d" />
</selector>

2. This is to set the text color

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:color="@color/colorGreenPrimary" android:state_checked="true" />
    <item android:color="@color/color_80" />
</selector>

3. This is the layout and style file of RadioButton, checked="true" is the default selected button

<RadioButton
    android:id="@+id/rBtn_3d"
    style="@style/main_radioButton_style"
    android:drawableTop="@drawable/select_3d_btn_img"
    android:text="3D相册"
    android:textColor="@drawable/select_main_tv_color"
    android:checked="true"/>

<style name="main_radioButton_style">
    <item name="android:layout_width">0dp</item>
    <item name="android:layout_height">match_parent</item>
    <item name="android:layout_weight">1</item>
    <item name="android:gravity">center</item>
    <item name="android:textSize">14sp</item>
    <item name="android:paddingTop">3dp</item>
    <item name="android:paddingEnd">3dp</item>
    <item name="android:button">@null</item>
</style>

4. Finally insert a toolbar title color setting:

Because the font of the toolbar is black by default, it is ugly; so we change it to white, where textColorPrimary is the key. A lot of people on Baidu say to use " actionMenuTextColor " without adding the android prefix, all of which will not work! It is estimated that it is a question of Level!

<style name="toolbarTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <item name="android:textColorPrimary">@color/color_white</item>
    <item name="android:textSize">18sp</item>
</style>

<android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/toolbar"
    android:layout_width="match_parent"
    android:layout_height="?attr/actionBarSize"
    android:background="@color/colorGreenPrimary"
    android:theme="@style/toolbarTheme">

</android.support.v7.widget.Toolbar>
