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
