从baseActivity android调用一个函数

Question

I have an activity BaseActivity. BaseActivity has a broadcast set as

private final BroadcastReceiver mReceivedReceiver = new BroadcastReceiver() 
    {
        @Override
        public void onReceive(Context context, Intent intent) 
        {
            String action = intent.getAction();
            mDialog.dismiss();
            if (Constants.ACTION_REQUEST_QUOTE.equals(action)) 
            {
                requestQuoteViewer();
                mDialog.dismiss();
            }
            if (Constants.ACTION_PUSH.equals(action))
            {
               // CALL A FUNCTION IN MYACTIVITY
            }
        }
    };    

Now I have many activities eg MyActivity extends BaseActivity On broadcast receive, i want to call a function defined in MyActivity (mainly UI Changes). How can I call a function in MyActivity from BaseActivity

Answer 1

Create a method abstract in the base class and implement it in the derived class (MainActivity).

add abstract modifier to your BaseActivity:

public abstract class BaseActivity extends Activity

Create an abstract method in your base activity

public abstract void test();

then, override it in the derived activity (Main Activity).

@Override
public void test() {
    // TODO Auto-generated method stub      
}

In your base activity you can call it normally.

test();

Now, you will have multiple implementations on test method based on the Activity that is running now. Each implementation will function differently corresponding to the running activity.
