xml代码：

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

    android:orientation="vertical"
    android:paddingVertical="25dp"

    tools:context=".AdbRunActivity">

    <EditText
        android:id="@+id/activity_adb_run_cmd_et"
        android:gravity="center"
        android:layout_width="match_parent"
        android:layout_height="40dp"
        android:hint="@string/activity_adb_run_cmd"/>

    <Button
        android:id="@+id/activity_adb_run_cmd_bt"

        android:text="@string/activity_adb_run_cmd_run"
        android:textAllCaps="false"
        android:background="@color/purple_200"/>

</LinearLayout>

主代码：

需要输入正确的adb shell 命令，实际运行只需要adb shell 后面的命令
