android - 使用 Parcelable 将对象从一个 android Activity 传递到另一个

Question

我想做这个

class A extends Activity{
       private class myClass{
       }
       myClass obj = new myClass();

      intent i = new Intent();
      Bundle b = new Bundle();
      b.putParcelable(Constants.Settings, obj); //I get the error The method putParcelable(String, Parcelable) in the type Bundle is not applicable for the arguments (int, A.myClass)
      i.setClass(getApplicationContext(),B.class);
      startActivity(i);  
    }

如何使用 Parcelable 将 obj 传递给 Activity B？

Answer 1

创建你的类并实现Serializable:

private class myClass implements Serializable  {
   }

并喜欢:

myClass obj = new myClass();
Intent aActivity = (A.this, B.class);
intent.putExtra("object", obj);

在接收端:

myClass myClassObject = getIntent().getSerializableExtra("object");
