利用DrawerLayout和触摸事件分发实现抽屉侧滑效果-创新互联

本文实例为大家分享了DrawerLayout和触摸事件分发实现抽屉侧滑效果的具体代码，供大家参考，具体内容如下

效果展示

还是看代码实在，直接上菜了。

1.MainActivity的代码：

public class MainActivity extends AppCompatActivity implements  MyDraweLayout.GetPositionCallback {

    private List imageList;
    private ViewPager viewPager;
    private MyAdapter adapter;
    private MyDraweLayout myDraweLayout;
    private int currentPosition;

    @Override
    protected void onCreate (Bundle savedInstanceState){
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    viewPager = (ViewPager) findViewById(R.id.viewpager);
    myDraweLayout = (MyDraweLayout) findViewById(R.id.mydrawelayout);
    initdata();
    adapter = new MyAdapter(this, imageList);
     myDraweLayout.setCallback(this);
    viewPager.setAdapter(adapter);
      viewPager.addOnPageChangeListener(new ViewPager.OnPageChangeListener() {
        @Override
        public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {

        }

        @Override
        public void onPageSelected(int position) {
          currentPosition=position;
        }

        @Override
        public void onPageScrollStateChanged(int state) {

        }
      });

  }
  private void initdata() {
    imageList = new ArrayList();

    ImageView imageView = new ImageView(this);
    imageView.setImageResource(R.mipmap.ic_launcher);
    imageView.setScaleType(ImageView.ScaleType.FIT_XY);
    imageList.add(imageView);

    imageView = new ImageView(this);
    imageView.setImageResource(R.mipmap.ic_launcher);
    imageView.setScaleType(ImageView.ScaleType.FIT_XY);
    imageList.add(imageView);

    imageView = new ImageView(this);
    imageView.setImageResource(R.mipmap.ic_launcher);
    imageView.setScaleType(ImageView.ScaleType.FIT_XY);
    imageList.add(imageView);

    imageView = new ImageView(this);
    imageView.setImageResource(R.mipmap.ic_launcher);
    imageView.setScaleType(ImageView.ScaleType.FIT_XY);
    imageList.add(imageView);


  }


  @Override
  public int position() {
    return currentPosition;//TODO 通过接口回调把当前位置传到MyDraweLayout中
  }
}
