Android中如何实现页面跳转
Android中怎样实现页面跳转啊?试了好多次,有时可以,但大多数时候总是会报错!下面是我写的一个小例子,在模拟器中运行的时候就会显示:应用程序意外停止!
下面是java代码:
main.xml<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<TextView
android:id="@+id/titleView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:text="@string/titleLable"
android:textAppearance="?android:attr/textAppearanceLarge"
android:textColor="@color/titleCocle"
android:textSize="30sp" />
<Button
android:id="@+id/timeButton"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="@string/timeLable"
android:textColor="@color/textColor"
android:textSize="25sp" />
</LinearLayout>
time.xml<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<TextView
android:id="@+id/timeView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:text="@string/TimeLable"
android:textAppearance="?android:attr/textAppearanceLarge"
android:textColor="@color/titleCocle"
android:textSize="30sp" />
<TextView
android:id="@+id/startView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/timeStartLable"
android:textAppearance="?android:attr/textAppearanceLarge" />
<Button
android:id="@+id/backButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/backLable" />
</LinearLayout>
