我不知道为什么我会收到这个例外setContentView(R.layout.activity_main);.我试图清理这个项目,REBUILD,RERUN,REEVERYTHING ....但没有任何作用.

这是文件:

MainActivity.java

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    recyclerView1 = (RecyclerView) findViewById(R.id.recycleView1);
    adapter1 = new MyCustomAdapter(this, Group.getData());
    recyclerView1.setAdapter(adapter1);
    GridLayoutManager mGridLayoutManager = new GridLayoutManager(this, 5); // (Context context, int spanCount)
    recyclerView1.setLayoutManager(mGridLayoutManager);

    recyclerView = (RecyclerView) findViewById(R.id.recycleView);
    adapter = new MyCustomAdapter(this, Data.getData());
    recyclerView.setAdapter(adapter);
    LinearLayoutManager mLinearLayoutManagerHorizontal = new LinearLayoutManager(this); // (Context context)
    mLinearLayoutManagerHorizontal.setOrientation(LinearLayoutManager.HORIZONTAL);
    recyclerView.setLayoutManager(mLinearLayoutManagerHorizontal);
    adapter.setAddapter(adapter1);
    adapter1.setAddapter(adapter);
   final RecyclerViewFastScroller fastScroller = (RecyclerViewFastScroller) findViewById(R.id.fastscroller);
    fastScroller.setRecyclerView(recyclerView);
   fastScroller.setViewsToUse(R.layout.recycler_view_fast_scroller__fast_scroller, R.id.fastscroller_bubble, R.id.fastscroller_handle);



}
public boolean onCreateOptionsMenu(final Menu menu) {
    getMenuInflater().inflate(R.menu.activity_main, menu);
    return super.onCreateOptionsMenu(menu);
} …
