如何从 Activity 的包含类启动 Intent

发布于 2024-11-15 01:14:17 字数 584 浏览 0 评论 0原文

我正在寻找从不是 Activity 而是 Activity 类的包含对象的类启动意图的最佳方法。

例如，活动类：

Class MainActivity extends ListActivty
{
...
TestLauncher tester;
}

以及我想要从中启动意图的类：

Class TestLauncher
{
   public TestLauncher ()
   {
      //Code to create an intent needs a Context
      //Intent i = new Intent(Context, class)

      //Code to start activity needs to be called with an Activity
      //Activity.StartActivity(i);
   }
}

在架构上执行此操作的最佳方法是什么？我应该将 MainActivity 作为参数传递给 TestLauncher 的构造函数吗？还是有我不知道的更好的方法？

I'm looking for the best way to start an intent from a class that is not an Activity, but is a contained object of an Activity class.

For example the Activity Class:

Class MainActivity extends ListActivty
{
...
TestLauncher tester;
}

and the class that I want to start the intent from:

Class TestLauncher
{
   public TestLauncher ()
   {
      //Code to create an intent needs a Context
      //Intent i = new Intent(Context, class)

      //Code to start activity needs to be called with an Activity
      //Activity.StartActivity(i);
   }
}

What is the best way to do this architecturally? Should I pass MainActivity as a parameter to TestLauncher's constructor? Or is there a better way that I am not aware of?

Class TestLauncher
{
   public TestLauncher (Context c)
   {
      Intent i = new Intent(c, YourActivity.class)
      c.startActivity(i);
   }
}

TestLauncher ts=new TestLauncher(getApplicationContext());

Class TestLauncher
{
   public TestLauncher (Context c)
   {
      Intent i = new Intent(c, YourActivity.class)
      c.startActivity(i);
   }
}

TestLauncher ts=new TestLauncher(getApplicationContext());
