一个简单的测试功能,一个界面提交数据,一个界面显示

先看运行效果:

布局文件activity_main.xml代码:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:id="@+id/container"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:orientation="vertical" >    <TableLayout        android:layout_width="match_parent"        android:layout_height="wrap_content" >        <TableRow            android:id="@+id/tableRow1"            android:layout_width="wrap_content"            android:layout_height="wrap_content" >            <TextView            android:id="@+id/textView1"            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:text="性别" />                  <RadioGroup                android:orientation="horizontal"                android:id="@+id/radioGroup1"                android:layout_width="wrap_content"                android:layout_height="wrap_content" >                <RadioButton                    android:id="@+id/man"                    android:layout_width="wrap_content"                    android:layout_height="wrap_content"                    android:checked="true"                    android:text="男" />                <RadioButton                    android:id="@+id/woman"                    android:layout_width="wrap_content"                    android:layout_height="wrap_content"                    android:text="女" />                            </RadioGroup>        </TableRow>        <TableRow            android:id="@+id/tableRow3"            android:layout_width="wrap_content"            android:layout_height="wrap_content" >            <TextView                android:id="@+id/textView2"                android:layout_width="wrap_content"                android:layout_height="wrap_content"                android:text="爱好" />            <CheckBox                android:id="@+id/football"                android:layout_width="wrap_content"                android:layout_height="wrap_content"                android:text="足球" />            <CheckBox                android:id="@+id/basketball"                android:layout_width="wrap_content"                android:layout_height="wrap_content"                android:text="篮球" />        </TableRow>        <TableRow            android:id="@+id/tableRow4"            android:layout_width="wrap_content"            android:layout_height="wrap_content" >            <TextView                android:id="@+id/textView3"                android:layout_width="wrap_content"                android:layout_height="wrap_content"                android:text="职务" />            <Spinner                android:id="@+id/position"                android:layout_width="wrap_content"                android:layout_height="wrap_content" />        </TableRow>    </TableLayout>    <Button                android:id="@+id/submit"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:text="提交" /></LinearLayout>
