    W/OpenGLRenderer: Failed to set EGL_SWAP_BEHAVIOR on surface 0xafaff140, error=EGL_BAD_MATCH 

ich ein paar Sachen ausprobiert, aber hat nicht funktioniert. Ich weiß nicht, wo ich falsch gelaufen bin. Hier ist mein Adapter Code

public class WordsAdapter extends RecyclerView.Adapter<WordsAdapter.ViewHolder> { 

     private ArrayList<Words> mWords; 
     private Context mContext; 

     public WordsAdapter(Context context , ArrayList<Words> words) 
     { 
      mWords = words; 
      mContext = context; 
     } 
     private Context getContext(){return mContext;} 

     @Override 
     public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) { 
      Context context = parent.getContext(); 
      LayoutInflater inflater = LayoutInflater.from(getContext()); 
      View view = inflater.inflate(R.layout.list_item , parent ,false); 
      ViewHolder viewHolder = new ViewHolder(view); 

      return viewHolder; 
     } 

     @Override 
     public void onBindViewHolder(ViewHolder holder, int position) { 

      Words word = mWords.get(position); 

      TextView title = holder.title; 
      title.setText(word.getTitle()); 

      TextView subtitle = holder.subtitle; 
      subtitle.setText(word.getSubtitle()); 

     } 

     @Override 
     public int getItemCount() { 
      return mWords.size(); 
     } 

     public static class ViewHolder extends RecyclerView.ViewHolder{ 

      public TextView title , subtitle; 

      public ViewHolder(View itemView) { 
       super(itemView); 
       title = (TextView) itemView.findViewById(R.id.title); 
       subtitle = (TextView) itemView.findViewById(R.id.subtitle); 
      } 
     } 
    } 

Hier meine MainActivity Java-Datei ist

private static final String[] title = { "ABCD" , "EFGH" , "IJKL" , "MNOP", "QRST" , "UVW" , "XYZ"}; 
    private static final String[] subtitle = {"abcd" , "efgh" , "ijkl" , "mnop" , "qrst", "uvw" , "xyz"}; 
    private ArrayList<Words> words; 

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

     words = new ArrayList<>(); 
     for (int i=0 ; i<title.length ; i++) 
     { 
      words.add(new Words(title[i] , subtitle[i])); 
     } 

     RecyclerView rvWords = (RecyclerView) findViewById(R.id.rv_words); 

     WordsAdapter adapter = new WordsAdapter(MainActivity.this , words); 

     rvWords.setLayoutManager(new LinearLayoutManager(this)); 



     rvWords.setAdapter(adapter); 

    } 
} 

Hier ist mein Layout-Element xml-Code

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
     android:orientation="vertical" android:layout_width="match_parent" 
     android:layout_height="match_parent"> 

     <TextView 
      android:id="@+id/title" 
      android:layout_width="match_parent" 
      android:layout_height="wrap_content" 
      android:textSize="?attr/titleTextAppearance" 
      android:textStyle="bold" 
      /> 
     <TextView 
      android:layout_width="match_parent" 
      android:layout_height="wrap_content" 
      android:id="@+id/subtitle" 
      android:textSize="?attr/subtitleTextAppearance" 
      /> 

    </LinearLayout> 

und der Recycler Ansicht XML-Code

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
xmlns:tools="http://schemas.android.com/tools" 
android:id="@+id/activity_main" 
android:layout_width="match_parent" 
android:layout_height="match_parent" 
tools:context="com.example.sriran.recyclerview.MainActivity"> 

<android.support.v7.widget.RecyclerView 
    android:id="@+id/rv_words" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent"> 

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

Bitte helfen Sie mir herauszufinden, wo ich falsch gelaufen bin

Answer 1

Entfernen Sie diese android:textSize="?attr/titleTextAppearance" aus Ihrer Liste oder korrigieren Sie die Datei, um Ihr Problem zu beheben.

Answer 2

zu Ihrem Artikel-Layout ändern

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
android:orientation="vertical" android:layout_width="match_parent" 
android:layout_height="match_parent"> 

<TextView 
    android:id="@+id/title" 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:textSize="10sp" 
    android:textStyle="bold" 
    /> 
<TextView 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:id="@+id/subtitle" 
    android:textSize="10sp" 
    /> 

Ich denke an Compiler kann in der Lage herauszufinden, "? Attr/titleTextAppearance" und "? Attr/subtitleTextAppearance" -Attribut es einfach so sagen und

Answer 3

entfernen versuchen diese android:textSize="?attr/titleTextAppearance" von Ihrem Adapter Artikel Layout und liefert Textgröße Ihren Bedarf entsprechend. (Hier verwende ich 16sp und 14sp als Beispiel)

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
     android:orientation="vertical" 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" 
     <TextView 
      android:id="@+id/title" 
      android:layout_width="match_parent" 
      android:layout_height="wrap_content" 
      android:textSize="16sp" 
      android:textStyle="bold"/> 
     <TextView 
      android:layout_width="match_parent" 
      android:layout_height="wrap_content" 
      android:id="@+id/subtitle" 
      android:textSize="14sp"/> 
    </LinearLayout> 

Answer 4

Sie Ihren Code entfernen subtitleTextAppearance

android:textSize="16dp" 

Da das System nicht in der Lage zu bekommen von den Eltern Textgröße statt Verwendung zu holen.
