Android 跳转应用市场的应用详情页

工具类

 public static Intent getIntent(Context paramContext)
  {
    StringBuilder localStringBuilder = new StringBuilder().append("market://details?id=");
    String str = paramContext.getPackageName();
    localStringBuilder.append(str);
    Uri localUri = Uri.parse(localStringBuilder.toString());
    return new Intent("android.intent.action.VIEW", localUri);
  }

  //直接跳转不判断是否存在市场应用
  public static void start(Context paramContext, String paramString)
  {
    Uri localUri = Uri.parse(paramString);
    Intent localIntent = new Intent("android.intent.action.VIEW", localUri);
    localIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    paramContext.startActivity(localIntent);
  }

  public static boolean judge(Context paramContext, Intent paramIntent)
  {
    List<ResolveInfo> localList = paramContext.getPackageManager().queryIntentActivities(paramIntent,PackageManager.GET_INTENT_FILTERS);
    if ((localList != null) && (localList.size() > 0)){
     return false;  
  }else{
  return true;
  } 
    }

实现跳转

Intent i = GetUri.getIntent(GetMarketActivity.this);
        boolean b = GetUri.judge(GetMarketActivity.this, i);
        if(b==false)
        {
          startActivity(i);
        }
