android.content.res.Resources $ NotFoundException：リソースID＃0x7f040019

Question

私はなぜその例外がラインsetContentView(R.layout.activity_main);で受信されるのかわかりません。 REBUILD、RERUN、REEVERYTHING ....プロジェクトをクリーンアップしようとしましたが、何も動作しません。

これはファイルです：

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); 
}

Answer 1

あなたはそれが下のAPIエミュレータ上で実行しているたびにシステムが戻って、そのファイルにデフォルトすることができますので、V21修飾子なしactivity_main.xmlファイルを作成する必要があります。あなたが修飾子in this linkについての詳細を学ぶことができ
