Gridview dans Android ne montre pas les caractères

Question

Je crée un jeu de recherche de mots avec des grilles 10x10 dans un gridview. Les alphabets ne sont pas entièrement affichés dans chaque cellule. Voici les Screen shot of gridview with characters filled in

Les extraits de code sont donnés ci-dessous:

MainActivity.java

MainActivity public class étend AppCompatActivity {

GridView gridView; 

static final String[] numbers = new String[] { 
     "A", "B", "C", "D", "E", "F", "G", "H", "I", "J", 
     "L", "M", "N", "O", "P", "Q", "R", "S", "T", "U", 
     "W", "X", "Y", "Z", "A", "B", "C", "D", "E", "F", 
     "L", "M", "N", "O", "P", "Q", "R", "S", "T", "U", 
     "A", "B", "C", "D", "E", "F", "G", "H", "I", "J", 
     "L", "M", "N", "O", "P", "Q", "R", "S", "T", "U", 
     "W", "X", "Y", "Z", "A", "B", "C", "D", "E", "F", 
     "L", "M", "N", "O", "P", "Q", "R", "S", "T", "U", 
     "A", "B", "C", "D", "E", "F", "G", "H", "I", "J", 
     "L", "M", "N", "O", "P", "Q", "R", "S", "T", "U", 
}; 


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


    gridView = (GridView) findViewById(R.id.gridView1); 

    ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, 
      android.R.layout.simple_list_item_1, numbers); 

    gridView.setAdapter(adapter); 

    gridView.setOnItemClickListener(new AdapterView.OnItemClickListener() { 
     public void onItemClick(AdapterView<?> parent, View v, 
           int position, long id) { 
      Toast.makeText(getApplicationContext(), 
        ((TextView) v).getText(), Toast.LENGTH_SHORT).show(); 
     } 
    }); 
} 

}

activity_main.xml

<?xml version="1.0" encoding="utf-8"?> 
<GridView xmlns:android="http://schemas.android.com/apk/res/android" 
xmlns:tools="http://schemas.android.com/tools" 

android:paddingBottom="@dimen/activity_vertical_margin" 
android:paddingLeft="@dimen/activity_horizontal_margin" 
android:paddingRight="@dimen/activity_horizontal_margin" 
android:paddingTop="@dimen/activity_vertical_margin" 

android:id="@+id/gridView1" 
android:numColumns="10" 
android:gravity="center" 
android:columnWidth="50dp" 
android:stretchMode="columnWidth" 
android:layout_width="fill_parent" 
android:layout_height="fill_parent" 

tools:context="in.viyanservices.wordsearch1.MainActivity"> 
</GridView> 

J'ai suivi ce tutoriel: http://www.mkyong.com/android/android-gridview-example/. Il a utilisé Android: numColumns = "auto_fit". J'utilise android: numColumns = "10"

Votre réponse serait appréciée! Merci beaucoup!

Answer 1

Mettez à jour votre GridView XML

<?xml version="1.0" encoding="utf-8"?> 
    <HorizontalScrollView xmlns:android="http://schemas.android.com/apk/res/android" 
     xmlns:tools="http://schemas.android.com/tools" 
     tools:context="in.viyanservices.wordsearch1.MainActivity" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content"> 
    <GridView 
     android:id="@+id/gridView1" 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" 
     android:gravity="center" 
     android:numColumns="10"/> 
    </HorizontalScrollView> 

Answer 2

il suffit de changer votre propriété xml

android:stretchMode="spacingWidth"
