三、报错实例 示例: 假设我们有一个函数定义,但由于忘记在参数列表后面加分号,导致出现"Error:expected ‘;’ after expression"的错误。..., int b) { // 函数体 } 为了解决这个问题,我们只需要在参数列表后面加上分号: // 正确的函数定义 void func(int a, int b); 总结 遇到"Error:expected...‘;’ after expression"错误时,请检查您的代码中是否有表达式后面缺少分号的情况,并使用适当的解决方法来修复它。
隐式意图和显式意图: 显式意图:显式意图明确指明了启动活动的上下文和想要启动的目标活动,显式意图明确指定了Intent应该传递给哪个组件。 隐式意图:没有明确指定组件名的Intent为隐式意图。...Android系统会根据隐式意图中设置的动作(action)、类别(category)、数据(URI和数据类型)找到最合适的组件来处理这个意图。...开启自己应用的界面用显式意图,开启其他应用(一般指系统应用)的时候用隐式意图(比如拨打电话)。 显式意图安全一些,隐式意图可以通过匹配intent-filter里面的标签对应来跳转到相应的页面 。...wrap_content" android:onClick="onclick" android:text="隐式意图跳转到TestActivity" /> 意图的Intent中会添加默认的Category,所以隐式意图必须有 android:name="android.intent.category.DEFAULT" />这个标签
