我一直在编写一个包含BottomSheetBehavior的原生android模块.

一个非常简单的BottomSheetBehavior可以像这样实现 https://gist.github.com/cesardeazevedo/a4dc4ed12df33fe1877fc6cea42475ae

我面对的第一件事,整个页面必须是CoordinatorLayout的子节点和底部的BottomSheetBehavior.

所以我不得不写2个原生模块,<CoordinatorLayout />和<BottomSheetBehavior />.

这是bottomSheetBehavior包装器.

BottomSheetBehaviorManager.java

public class BottomSheetBehaviorManager extends ViewGroupManager<BottomSheetBehaviorView> {

    @Override
    public BottomSheetBehaviorView createViewInstance(ThemedReactContext context) {
        return new BottomSheetBehaviorView(context);
    }
}

BottomSheetBehaviorView.java

public class BottomSheetBehaviorView extends RelativeLayout {

    public BottomSheetBehaviorView(Context context) {
        super(context);

        int width  = ViewGroup.LayoutParams.WRAP_CONTENT;
        int height = ViewGroup.LayoutParams.WRAP_CONTENT;
        // int height = 1000; // fixed a height works, it only slide up half of the screen

        CoordinatorLayout.LayoutParams params = new CoordinatorLayout.LayoutParams(width, height);
        params.setBehavior(new BottomSheetBehavior());
        this.setLayoutParams(params);

        BottomSheetBehavior<BottomSheetBehaviorView> …
