我無法在主屏幕上的應用程序圖標上顯示通知計數

Question

你好我想在主屏幕上的應用程序圖標上顯示通知計數，但我無法做到這一點。

這是我的代碼。

public class MainActivity extends Activity { 
    ImageView img; 
    BadgeView badge; 
    public int badgeCount; 
    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 
      badgeCount = 0; 
      img = (ImageView)findViewById(R.id.notificationicon); 
      Drawable icon; 
      try { 
       icon = getPackageManager().getApplicationIcon("com.example.notificationapp"); 
        img.setImageDrawable(icon); 
        badge = new BadgeView(this, img); 
        badge.setText("10"); 

      } catch (NameNotFoundException e1) { 
       // TODO Auto-generated catch block 
       e1.printStackTrace(); 
      } 

      badge = new BadgeView(this, img); 
      badge.setText("10"); 

      badgeCount = Integer.parseInt("5"); 
      ShortcutBadger.with(getApplicationContext()).count(badgeCount); 
      img.setOnClickListener(new OnClickListener() { 
       @Override 
       public void onClick(View v) { 
        if (badge.isShown()) { 
         try { 
           badgeCount = Integer.parseInt("5"); 
          } catch (NumberFormatException e) { 
           Toast.makeText(getApplicationContext(), "Error input", Toast.LENGTH_SHORT).show(); 
          } 

//        ShortcutBadger.setBadge(getApplicationContext(), badgeCount); 
          ShortcutBadger.with(getApplicationContext()).count(badgeCount); 

          Toast.makeText(getApplicationContext(), "Set count=" + badgeCount, Toast.LENGTH_SHORT).show(); 
         badge.decrement(1); 
        } else { 
//      badge.decrement(1); 
         badge.show(); 
        } 
       } 
      }); 
      Intent intent = new Intent(Intent.ACTION_MAIN); 
      intent.addCategory(Intent.CATEGORY_HOME); 
      ResolveInfo resolveInfo = getPackageManager().resolveActivity(intent, PackageManager.MATCH_DEFAULT_ONLY); 
      String currentHomePackage = resolveInfo.activityInfo.packageName; 
      ShortcutBadger.with(getApplicationContext()).count(badgeCount); 
      TextView textViewHomePackage = (TextView) findViewById(R.id.textViewHomePackage); 
      textViewHomePackage.setText("launcher:" + currentHomePackage); 
    } 

使用這兩行代碼來設置應用圖標的通知計數。

ShortcutBadger.setBadge(getApplicationContext(), badgeCount); 
           ShortcutBadger.with(getApplicationContext()).count(badgeCount); 

但是，我不能這樣做。

ShortcutBadger只支持一些第三方發射器。

它不支持在許多設備和模擬器上的股票Android啓動器。
