android片段 - 如何充气布局然后制作UI功能

Question

I have a Fragment instance, and I would like to be able to implement click listeners and other attributes after the fragment is loaded and shown on screen. How can I achieve this? Where should I be doing this implenentation?

Answer 1

Try the following:

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    View v = inflater.inflate(R.layout.rap_prog_fields, container, false);
    TextView tv = (TextView) v.findViewById(R.id.text_view_1);
    Button b = (Button) v.findViewById(R.id.button);
    b.setOnClickListener(new View.OnClickListener() {
         public void onClick(View v) {
             //do stuff
         }
     });
    //the rest of your views... in the same manner

    return v;
}

You can also find your views after returning from onCreateView like such:

public void onStart() {
     super.onStart();
     Button b = (Button) getView().findViewById(R.id.button);
     b.setOnClickListener(new View.OnClickListener() {
         public void onClick(View v) {
             //do stuff
         }
     });
     //Everything else...
 }

TO complete actions once the view is displayed and on the screen you need to implement the following:

final ViewTreeObserver observer= button.getViewTreeObserver(); //you need an anchor view here that will be drawn via xml
       observer.addOnGlobalLayoutListener(new OnGlobalLayoutListener() {
            @Override
            public void onGlobalLayout() {
                //do stuff here.....
    }
});
