selector.xml的使用

TextView:

<TextView
            android:id="@+id/resetfragment_btn"
            app:layout_constraintTop_toBottomOf="@+id/reset_tip"
            android:layout_marginTop="20dp"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_marginBottom="10dp"
            android:background="@drawable/selector_backgroud_btn"
            android:clickable="true"
            android:textColor="@drawable/selector_color_btn"
            android:paddingLeft="40dp"
            android:paddingRight="40dp"
            android:paddingTop="10dp"
            android:paddingBottom="10dp"
            android:text="@string/reset" />

下面👇是背景框的selector：

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

    <item android:drawable="@drawable/shape_background_selected" android:state_pressed="true" />
    <item android:drawable="@drawable/shape_background_normal" android:state_pressed="false" />

</selector>

下面是textview文字颜色的selector：

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

    <item android:color="@color/colorAccent" android:state_pressed="true" />
    <item android:color="@color/color_word_normal" android:state_pressed="false" />

</selector>
