Question

I found this on android developers when i was trying to program a button:android developers blog: UI framework changes in Android 1.6

With Android 1.6, none of this is necessary. All you have to do is declare a public method in your Activity to handle the click (the method must have one View argument):

class MyActivity extends Activity {    public void myClickHandler(View target){        
// Do stuff    
}
}

And then reference this method from your XML layout:

<Button android:onClick="myClickHandler" />

can smeone please explain this code to me? I am a beginner in programming, and I don’t know what to put in the //do stuff space? I need to reference another activity so i can open another screen. And do i still need to have an activity and put a block of program in the class? this is the code i am using in the class at the moment. Please tell me if i need to update it to use this method:

package com.duncan.hello.world;
import com.duncan.hello.world.R;

import android.app.Activity;
import android.os.Bundle;
public class OtherActivity extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.other);
}
}

Answer 1

You put what you want to happen when the button is clicked in the // do stuff part.

You only need to update your code if you’re using a button click handler in this fashion.

You might want to start with something a bit simpler, and perhaps not target Android 1.6.
