Question

After trying a lot i decided to ask question on stackoverflow, I create a class for using on button click and start an intent from this class.

import android.app.Activity;
import android.content.Intent;
import android.view.View;

public class OnClickListener implements android.view.View.OnClickListener{

    Activity current;
    Object goTo;

    public OnClickListener(Activity arg0, Activity arg1){
        this.current = arg0;
        this.goTo = arg1;
    }

    @Override
    public void onClick(View v) {
        Intent intent = new Intent(current, goTo.getClass());
        current.startActivity(intent);
    }

}

and passing parameter like this:

Button button = (Button)findViewById(R.id.class2_btn);
        Class2 class2 = new Class2();
        OnClickListener listener = new OnClickListener(class1.this, class2);
        button.setOnClickListener(listener);

why this is not working? after clicking button why this is not going to next class?
Please help me.

Answer 1

There are some points i want to figure out here :

1. As you are using startActivty(), as the name suggests it is for activity not for simple class as you are trying here.Activity is like an UI that you can start but simple class is like a Model class they are not going start like activity.
2. If you will using activity in place of class then it will defiitely work.In that case you do not need to pass any argument just you can give name directly like below:

Intent intent = new Intent(current_activity.this, target_activty.class);
current.startActivity(intent);

1. If you class2 is an activity then you should give it directly to startActivty() as i sated in above point not it’s object like you did.And also ass this activity into menifest file.
