如何隱藏recyclerview頂部佈局viewpager

Question

滾動我用底部佈局

我想隱藏tablayout，相對從兩種佈局時recyclerview在viewpager

如果possiblely也想，隱藏之後的正常佈局可見結束

請一些幫助

這是我的佈局 layout.xml

Answer 1

創建延伸RecyclerView.OnScrollListener一個新的抽象類。

然後，你可以通過設置X移動項目，Y

public abstract class HidingScrollListener extends RecyclerView.OnScrollListener { 

private int mToolbarOffset = 0; 
private int mToolbarHeight; 

public HidingScrollListener(Context context) { 
    mToolbarHeight = Utils.getToolbarHeight(context); 
} 

@Override 
public void onScrolled(RecyclerView recyclerView, int dx, int dy) { 
    super.onScrolled(recyclerView, dx, dy); 

    clipToolbarOffset(); 
    onMoved(mToolbarOffset); 
    //The most important 
    if((mToolbarOffset <mToolbarHeight && dy>0) || (mToolbarOffset >0 && dy<0)) { 
     mToolbarOffset += dy; 
    } 
} 

private void clipToolbarOffset() { 
    if(mToolbarOffset > mToolbarHeight) { 
     mToolbarOffset = mToolbarHeight; 
    } else if(mToolbarOffset < 0) { 
     mToolbarOffset = 0; 
    } 
} 

public abstract void onMoved(int distance);} 

如何使用

private void initRecyclerView() { 
final RecyclerView recyclerView = (RecyclerView) findViewById(R.id.recyclerView); 
recyclerView.setLayoutManager(new LinearLayoutManager(this)); 
RecyclerAdapter recyclerAdapter = new RecyclerAdapter(createItemList()); 
recyclerView.setAdapter(recyclerAdapter); 

recyclerView.setOnScrollListener(new HidingScrollListener(this) { 
    @Override 
    public void onMoved(int distance) { 
     mToolbarContainer.setTranslationY(-distance); 
    } 
});}
