package com.example.rk_02;


import android.graphics.drawable.AnimationDrawable;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.Button;
import android.widget.ImageView;


/**
 * A simple {@link Fragment} subclass.
 */
public class AlankFragment extends Fragment {
    private View view;

    private Button start, stop;
    private AnimationDrawable animationDrawable;
    private ImageView mIv;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        // Inflate the layout for this fragment
        view = inflater.inflate(R.layout.fragment_alank, container, false);

        mIv = (ImageView) view.findViewById(R.id.iv);
        animationDrawable = (AnimationDrawable) mIv.getBackground();
        start = (Button) view.findViewById(R.id.start);
        stop = (Button) view.findViewById(R.id.stop);
        start.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                if (!animationDrawable.isRunning()) {
                    animationDrawable.start();
                }
            }
        });
        stop.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                animationDrawable.stop();
            }
        });
        return view;

    }
