Usage

1. Add SwipeBackLayout as a dependency to your existing project.
2. To enable SwipeBackLayout, you can simply make your Activity extend SwipeBackActivity:
   • In onCreate method, setContentView() should be called as usual.
   • You will have access to the getSwipeBackLayout() method so you can customize the SwipeBackLayout.
3. Make window translucent by adding <item name="android:windowIsTranslucent">true</item> to your theme.

修改内容

1.在使用systembarhint的时候，不生肖了。 解决方法：在SwipeBackLayout的attachToActivity中修改如下

//        ViewGroup decor = (ViewGroup) activity.getWindow().getDecorView();
      ViewGroup decor = (ViewGroup) activity.getWindow().getDecorView().findViewById(Window.ID_ANDROID_CONTENT);

2.在布局文件设置的背景怎么没效果了？ 解决办法：在SwipeBackLayout的attachToActivity中有如下：

TypedArray a = activity.getTheme().obtainStyledAttributes(new int[]{android.R.attr.windowBackground
});
int background = a.getResourceId(0, 0);
a.recycle();
decorChild.setBackgroundResource(background);

把我们的背景给替换了，把这段注释掉。注意（注释掉之后，因为windowIsTranslucent设置为tue,那么就会透明了，需要在布局文件中设置背景）

3.滑动的时候怎么显示桌面？ 原因：在4.4系统以下最底层的的Activity的windowIsTranslucent设置为tue，会有此问题，如A->B，如果A设置windowIsTranslucent为true，那么就会出现此问题。5.0以上没问题。

Simple Example

public class DemoActivity extends SwipeBackActivity implements View.OnClickListener {
    private int[] mBgColors;

    private static int mBgIndex = 0;

    private String mKeyTrackingMode;

    private RadioGroup mTrackingModeGroup;

    private SwipeBackLayout mSwipeBackLayout;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_demo);
        changeActionBarColor();
        findViews();
        mKeyTrackingMode = getString(R.string.key_tracking_mode);
        mSwipeBackLayout = getSwipeBackLayout();

        mTrackingModeGroup.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
            @Override
            public void onCheckedChanged(RadioGroup group, int checkedId) {
                int edgeFlag;
                switch (checkedId) {
                    case R.id.mode_left:
                        edgeFlag = SwipeBackLayout.EDGE_LEFT;
                        break;
                    case R.id.mode_right:
                        edgeFlag = SwipeBackLayout.EDGE_RIGHT;
                        break;
                    case R.id.mode_bottom:
                        edgeFlag = SwipeBackLayout.EDGE_BOTTOM;
                        break;
                    default:
                        edgeFlag = SwipeBackLayout.EDGE_ALL;
                }
                mSwipeBackLayout.setEdgeTrackingEnabled(edgeFlag);
                saveTrackingMode(edgeFlag);
            }
        });
    }
