android.view.InflateException：バイナリXMLファイルの行＃9：Android APIを使用したandroid.support.v7.widget.CardViewのエラー19

Question

私はそれが非常によくある質問であることを知っています。これまで私を助けてくれました。

私はAPIレベル19（私のminSdkVersionが19でコンパイルおよびtargetSDKのバージョンが25である）

でこの例外を取得しています私は、次のAPIレベルで実行されているエミュレータで試してみましたが、すべてが正常に動作します。以下は

API level 25 - works 
API level 23 - works 
API level 22 - works 
API level 21 - works 
API level 19 - crashes with following exception 

例外です：

以下

は私のGradleです：

apply plugin: 'com.android.application' 

android { 
    compileSdkVersion 25 
    buildToolsVersion "25.0.1" 
    defaultConfig { 
     applicationId "com.nitinsharma.materiallistview" 
     minSdkVersion 19 
     targetSdkVersion 25 
     versionCode 1 
     versionName "1.0" 
     testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner" 
    } 
    buildTypes { 
     release { 
      minifyEnabled false 
      proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' 
     } 
    } 

    dependencies { 
     compile fileTree(dir: 'libs', include: ['*.jar']) 
     androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', { 
      exclude group: 'com.android.support', module: 'support-annotations' 
     }) 
     testCompile 'junit:junit:4.12' 


     compile 'com.android.support:cardview-v7:25.+'

    } 

} 

、最終的に私のcard_view.xmlファイル：

</RelativeLayout> 

</android.support.v7.widget.CardView> 

</RelativeLayout> 

ライン私の中エラーが発生するコード：

public class CardRecycleViewAdapter extends RecyclerView.Adapter<CardViewHolder> { 


    @Override 
    public CardViewHolder onCreateViewHolder(ViewGroup parent, int viewType) { 
     Log.d("TAG","inside oncreateviewholder"); 
     **View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.card_view,parent,false);** 
     CardViewHolder viewHolder = new CardViewHolder(v,parent); 
     return viewHolder; 
    } 

私のjarファイル：

マイMainActivity：

public class MainActivity extends AppCompatActivity { 

    private RecyclerView mRecycleView; 
    private LinearLayoutManager mRecycleViewLayout; 
    private RecyclerView.Adapter mRecycleViewAdapter; 
    protected static int sizex=0; 
    protected static int sizey=0; 
    protected static int recycleViewHeight=0; 
    protected static RecyclerView sharedRecyclerView; 
    protected static Context mContext; 



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


     mRecycleViewLayout = new LinearLayoutManager(this); 
     mRecycleViewAdapter = new CardRecycleViewAdapter(); 
     mRecycleView = (RecyclerView) findViewById(R.id.recycleViewRight); 
     mRecycleView.setHasFixedSize(true); 
     mRecycleView.setLayoutManager(mRecycleViewLayout); 
     mRecycleView.setAdapter(mRecycleViewAdapter); 

.... 
} 

Answer 1

card_view:cardElevation="-1dp"値は>=0なければならないためである：で

1. ためのAPIレベルの

   static { 
   if (Build.VERSION.SDK_INT >= 21) { 
       IMPL = new CardViewApi21(); 
   } else if (Build.VERSION.SDK_INT >= 17) { 
       IMPL = new CardViewJellybeanMr1(); 
   } else { 
       IMPL = new CardViewGingerbread(); 
   } 
   IMPL.initStatic(); 
   

   }

2. 21未満であるので、CardViewJellybeanMr1が作成され;方法initialize(Context context, AttributeSet attrs, int defStyleAttr)は、このようなIMPL.initialize(mCardViewDelegate, context, backgroundColor, radius, elevation, maxElevation);

3. IMPLが呼び出します

4. CardViewJellybeanMr1#initializeでは、それはを起動するには、ここでそれは言う：

   if (shadowSize < 0f) { 
       throw new IllegalArgumentException("Invalid shadow size " + shadowSize + 
         ". Must be >= 0"); 
   } 
   

をshadowSizeはあなたのlogcatは何の `by`引き起こしたcardElevation
