SwipeBackLayout 右滑退出Activity

添加依赖：

implementation 'me.imid.swipebacklayout.lib:library:1.3.0'

使用代码：

import nsu.edu.com.library.SwipeBackActivity;
import nsu.edu.com.library.SwipeBackLayout;

public class DemoActivity extends SwipeBackActivity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_demo);
        // 可以调用该方法，设置是否允许滑动退出
        setSwipeBackEnable(true);
        SwipeBackLayout mSwipeBackLayout = getSwipeBackLayout();
        // 设置滑动方向，可设置EDGE_LEFT, EDGE_RIGHT, EDGE_ALL, EDGE_BOTTOM
        mSwipeBackLayout.setEdgeTrackingEnabled(SwipeBackLayout.EDGE_LEFT);
        // 滑动退出的效果只能从边界滑动才有效果，如果要扩大touch的范围，可以调用这个方法
        //mSwipeBackLayout.setEdgeSize(200);
    }
}
