如何獲取intent Intent.ACTION_VIEW，但不是Intent.ACTION_SEND

Question

在android中。某些應用程序在意圖過濾器中聲明瞭ACTION_VIEW和ACTION_SEND。我想獲得所有的ACTION_VIEW應用程序，但不是ACTION_SEND。可能嗎？謝謝。

Answer 1

搜索ACTION_SEND和ACTION_VIEW並通過循環檢查哪個應用程序具有並從列表中排除它們。

public ArrayList<ResolveInfo> getApps() { 
    ArrayList<ResolveInfo> result = new ArrayList<>(); 

    Intent view = new Intent(); 
    view.setAction(android.content.Intent.ACTION_VIEW); 
    view.setDataAndType(Uri.fromFile(new File("sdcard/blah/blah/blah")), "*/*"); 

    Intent send = new Intent(); 
    send.setAction(Intent.ACTION_SEND); 
    send.setDataAndType(Uri.fromFile(new File("sdcard/blah/blah/blah")), "*/*"); 

    PackageManager packageManager = this.getPackageManager(); 
    List<ResolveInfo> actionView = packageManager.queryIntentActivities(view, 0); 
    List<ResolveInfo> actionSend = packageManager.queryIntentActivities(send, 0); 

    for (ResolveInfo viewItem : actionView) { 
     boolean notFound = true; 

     for (ResolveInfo sendItem : actionSend) { 

      if (viewItem.activityInfo.name.equals(sendItem.activityInfo.name)) 
       notFound = false; 

      if (notFound) 
       result.add(viewItem); 
     } 
    } 


    return result; 
}
