 布局文件

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/LinearLayout1"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <Button
        android:id="@+id/btn"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center_horizontal"
        android:text="发送" />

    <EditText
        android:id="@+id/et"
        android:layout_width="match_parent"
        android:layout_height="150dp"
        android:layout_marginTop="10dp"
        android:background="@drawable/et_shape" />

    <TextView
        android:id="@+id/tv"
        android:layout_width="match_parent"
        android:layout_height="150dp"
        android:layout_marginTop="10dp"
        android:background="@drawable/tv_shape" />

</LinearLayout>

当用户在编辑框中输入内容，便可以在TextView中显示出来

温馨提示  ：

　　 运行项目之前，一定要把服务端先启动 ，在运行客户端
