Android obtain sharing application list detailed explanation and examples

Android obtain sharing application list detailed explanation and examples

If the ACTION_SEND attribute is included in the application, it proves that the application can be used for calls and sharing by third-party applications. How to get the sharing list of the function attribute, which is very useful for us to make applications. Recently, when we are doing this function, I have also made a custom sharing list and popped up in PopupWindow.

1. Layout:

popup_share.xml

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:andro 
  android:layout_width="fill_parent"  
  android:layout_height="wrap_content" > 
 <ListView  
    android:  
    android:background="#2F4F4F"  
    android:fadingEdge="none"  
    android:layout_width="fill_parent"  
    android:layout_height="wrap_content"  
    android:cacheColorHint="#00000000"  
    android:divider="#E2DD75"  
    android:dividerHeight="1.0dip"  
    android:headerDividersEnabled="true"  
    android:footerDividersEnabled="false" /> 
</LinearLayout>

popup_share_item.xml

&lt;?xml version="1.0" encoding="utf-8"?&gt; 
&lt;LinearLayout xmlns:andro 
  android:gravity="center_vertical"  
  android:layout_width="wrap_content"  
  android:layout_height="wrap_content"  
  android:padding="2.0dip" &gt; 
  &lt;ImageView  
    android:  
    android:layout_width="32.0dip"  
    android:layout_height="32.0dip"  
    android:layout_marginLeft="3.0dip"  
    android:scaleType="fitXY" /&gt; 
  &lt;TextView  
    android:  
    android:gravity="center"  
    android:layout_width="wrap_content"  
    android:layout_height="wrap_content"  
    android:text="share"  
    android:textColor="@color/white"  
    android:singleLine="true"  
    android:textSize="@dimen/s_size"  
    android:layout_marginLeft="3.0dip"  
    android:layout_marginRight="3.0dip" /&gt; 
&lt;/LinearLayout&gt;

2. Query the list of all supported and shared applications on the mobile phone

public List<ResolveInfo> getShareApps(Context context) {  
    List<ResolveInfo> mApps = new ArrayList<ResolveInfo>(); 
    Intent intent = new Intent(Intent.ACTION_SEND, null); 
    (Intent.CATEGORY_DEFAULT); 
    ("text/plain"); 
//   ("*/*"); 
    PackageManager pManager = (); 
    mApps = (intent,  
        PackageManager.COMPONENT_ENABLED_STATE_DEFAULT); 
    return mApps; 
  }

Note: ApplicationInfo is information obtained from a specific application. This information is collected from the corresponding <application> tags.

The ResolveInfo class is obtained by parsing an intent corresponding to an IntentFilter. It corresponds in part to the information collected from the <intent> tag.

Get the List list, I built my own AppInfo class, just build one by myself

private List<AppInfo> getShareAppList() {  
    List<AppInfo> shareAppInfos = new ArrayList<AppInfo>(); 
    PackageManager packageManager = getPackageManager(); 
    List<ResolveInfo> resolveInfos = getShareApps(mContext); 
    if (null == resolveInfos) { 
      return null; 
    } else { 
      for (ResolveInfo resolveInfo : resolveInfos) { 
        AppInfo appInfo = new AppInfo(); 
        (); 
//       showLog_I(TAG, "pkg>" +  + ";name>" + ); 
        (); 
        ((packageManager).toString()); 
        ((packageManager)); 
        (appInfo); 
      } 
    }     
    return shareAppInfos; 
  }

3. PopupWindow implementation

private void initSharePopupWindow(View parent) { 
    PopupWindow sharePopupWindow = null; 
    View view = null; 
    ListView shareList = null; 
    if(null == sharePopupWindow) { 
      //Load the layout file      view = ().inflate(.popup_share, null); 
      shareList = (ListView) (.share_list); 
      List&lt;AppInfo&gt; shareAppInfos = getShareAppList(); 
      final ShareCustomAdapter adapter = new ShareCustomAdapter(mContext, shareAppInfos); 
      (adapter); 
       
      (new OnItemClickListener() { 
 
        @Override 
        public void onItemClick(AdapterView&lt;?&gt; parent, View view, 
            int position, long id) { 
          // TODO Auto-generated method stub 
          Intent shareIntent = new Intent(Intent.ACTION_SEND); 
          AppInfo appInfo = (AppInfo) (position); 
          (new ComponentName((), ())); 
          ("text/plain"); 
//         ("*/*"); 
          //This is the organization content.          (Intent.EXTRA_TEXT, "test"); 
          (Intent.FLAG_ACTIVITY_NEW_TASK); 
          (shareIntent); 
        } 
      }); 
       
      sharePopupWindow = new PopupWindow(view,  
          (int)(160 * density), .WRAP_CONTENT); 
    } 
    // Make it focus    (true); 
    //Setting allows clicks to disappear outside    (true); 
    // This is to click "Back Back" to make it disappear and will not affect your background    (new BitmapDrawable()); 
    //xoff,yoff is offset based on the lower left corner of anchor.  Positive numbers represent the right below, negative numbers represent (top left above)    //showAsDropDown(parent, xPos, yPos); 
    (parent, -5, 5); 
  }

Note: Just build one of ShareCustomAdapter by yourself. (Showing there will be an icon and a shared name)
