android.content.res.Resources $ NotFoundException：资源ID＃0x7f040019

我不知道为什么我在行setContentView(R.layout.activity_main);收到该exceptionsetContentView(R.layout.activity_main); 。 我试图清理项目，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); } 

V21 / activity_main.xml中

您需要创建一个不带v21限定符的activity_main.xml文件，以便系统可以在较低的API模拟器上运行时默认返回该文件。

您的资源最终应该是这样的：
