顯跳轉的運用

 

兩個簡單的布局：

main

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:orientation="vertical"    tools:context=".MainActivity" >    <EditText        android:id="@+id/et_name"        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:hint="請輸入姓名：" />    <RadioGroup        android:id="@+id/radioGroup1"        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:orientation="horizontal" >        <RadioButton            android:id="@+id/rb_male"            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:text="男" />        <RadioButton            android:id="@+id/rb_female"            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:layout_marginLeft="25dp"            android:text="女" />    </RadioGroup>    <Button        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:onClick="click"        android:text="計算" /></LinearLayout>

 

result:
