GridView onClickListener/onItemClickListener funktioniert nicht

Question

Ich versuche, eine Kartenansicht innerhalb der Rasteransicht zu implementieren. Die Rasteransicht zeigt perfekt; selbst wenn ich ein Gitteransichtselement berühre, zeigt es nichts. Aber wenn ich auf den Text klicke, der unter seiner Arbeit angezeigt wird. Ich erwähnte This, aber nicht funktioniert ...

Danke.

Mein Code ist wie unten,

// Contact_Backup.java

public class Contact_Backup extends AppCompatActivity { 

     @Bind(R.id.gridview) 
     GridView gridview; 
     String[] contact_screen_array; 
     @Override 
     protected void onCreate(Bundle savedInstanceState) { 
      super.onCreate(savedInstanceState); 
      setContentView(R.layout.contact_backup); 
      ButterKnife.bind(this); 
      contact_screen_array = getResources().getStringArray(R.array.TextScreen); 
      String[] contact_icon_array = getResources().getStringArray(R.array.IconScreen); 
      String concat = "\nContacts"; 
      gridview.setAdapter(new Custom_Adapter(getApplicationContext(),contact_icon_array,contact_screen_array,concat)); 
     } 
    } 

// Custom_Adapter

public class Custom_Adapter extends BaseAdapter { 

    Context contaxt; 
    String[] Array_text; 
    String[] Array_icon; 
    String concat; 
    LayoutInflater inflater; 

    public Custom_Adapter(Context context,String[] Array_icon, String[] Array_text, String concat) 
    { 
     this.contaxt = context; 
     this.Array_text = Array_text; 
     this.Array_icon = Array_icon; 
     this.concat=concat; 
     inflater = (LayoutInflater)context. 
       getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
    } 
    @Override 
    public int getCount() { 
     return Array_text.length; 
    } 
    @Override 
    public Object getItem(int position) { 
     return position; 
    } 
    @Override 
    public long getItemId(int position) { 
     return position; 
    } 


    @Bind(R.id.Screen_icon) 
    Button Screen_icon; 
    @Bind(R.id.Screen_text) 
    TextView Screen_text; 

    @Override 
    public View getView(final int position, View convertView, ViewGroup parent) { 
     View grid; 
     LayoutInflater inflater = (LayoutInflater) contaxt 
       .getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
     if (convertView == null) { 
      grid = new View(contaxt); 
      grid = inflater.inflate(R.layout.new_app_card_layout, null); 
      ButterKnife.bind(this, grid); 
      Screen_text.setText(Array_text[position]+concat); 
      Screen_icon.setText(Array_icon[position]); 
      Typeface font = Typeface.createFromAsset(contaxt.getAssets(), "fonts/fontawesome-webfont.ttf"); 
      Screen_icon.setTypeface(font); 
     } else { 
      grid = (View) convertView; 
     } 

     grid.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View v) { 
       Log.d("TAG::",""+position); 
      } 
     }); 
     return grid; 
    } 
}

Answer 1

Setzen Sie den Listener auf das tatsächliche Objekt gridview. class.please überprüfen wieder mit diesem aktualisierten Code gridView.setOnItemClickListener(new OnItemClickListener()...);

die Sie interessieren,

public class Contact_Backup extends AppCompatActivity { 

     @Bind(R.id.gridview) 
     GridView gridview; 
     String[] contact_screen_array; 
     @Override 
     protected void onCreate(Bundle savedInstanceState) {

        for(int i=0;i<contact_screen_array.length;i++) { 
         Log.d("TAG::", "Position"+contact_screen_array[i]); 
        } 
       } 
      }); 
     } 
    }

Try this Ich habe Ihre individuelle Adapter aktualisiert.

public class Custom_Adapter extends BaseAdapter { 

    Context contaxt; 
    String[] Array_text; 
    String[] Array_icon; 
    String concat; 
    LayoutInflater inflater; 

    public Custom_Adapter(Context context,String[] Array_icon, String[] Array_text, String concat) 
    { 
     this.contaxt = context; 
     this.Array_text = Array_text; 
     this.Array_icon = Array_icon; 
     this.concat=concat; 
     inflater = (LayoutInflater)context. 
       getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
    } 
    @Override 
    public int getCount() { 
     return Array_text.length; 
    } 
    @Override 
    public Object getItem(int position) { 
     return position; 
    } 
    @Override 
    public long getItemId(int position) { 
     return position; 
    } 


    @Bind(R.id.Screen_icon) 
    Button Screen_icon; 
    @Bind(R.id.Screen_text) 
    TextView Screen_text; 

    @Override 
    public View getView(final int position, View convertView, ViewGroup parent) { 
     View grid; 
     LayoutInflater inflater = (LayoutInflater) contaxt 
       .getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
     if (convertView == null) { 
      grid = new View(contaxt); 
      grid = inflater.inflate(R.layout.new_app_card_layout, null); 
      ButterKnife.bind(this, grid); 
      Screen_text.setText(Array_text[position]+concat); 
      Screen_icon.setText(Array_icon[position]); 
      Typeface font = Typeface.createFromAsset(contaxt.getAssets(), "fonts/fontawesome-webfont.ttf"); 
      Screen_icon.setTypeface(font); 

      grid.setOnClickListener(new View.OnClickListener() { 
       @Override 
       public void onClick(View v) { 
        Log.d("TAG::",""+position); 
       } 
      }); 

     } else { 
      grid = (View) convertView; 

      grid.setOnClickListener(new View.OnClickListener() { 
       @Override 
       public void onClick(View v) { 
        Log.d("TAG::",""+position); 
       } 
      }); 
     } 
     return grid; 
    } 
} 

Hoffe das hilft dir aus!

Answer 4

Verwendung dieses Verfahren auf einem gridview Artikel für klicken:

gridview.setOnItemClickListener(new AdapterView.OnItemClickListener() { 
     @Override 
     public void onItemClick(AdapterView<?> parent, View view, int position, long id) { 

     // your action when gridView item is clicked 

     } 
    }); 

Answer 5

Schließlich gelingt es mir. Hier ist der Code.

Verwenden Sie Textview anstelle von Button in // new_app_card_layout.xml.

es einfach aktualisieren,

<TextView 
     android:textSize="35.0sp" 
     android:textColor="@color/newclr" 
     android:layout_gravity="center" 
     android:id="@+id/Screen_icon" 
     android:background="@null" 
     android:padding="20sp" 
     android:layout_width="fill_parent" 
     android:layout_height="wrap_content" 
     android:text="@string/fa_icon_contact" 
     android:drawablePadding="5.0dip" 
     android:textAllCaps="false" 
     android:textAlignment="center" /> 

danken Sie so sehr, sie alle um Hilfe ... :)
