Android编程实现自定义分享列表ACTION_SEND功能的方法
本文实例讲述了Android编程实现自定义分享列表ACTION_SEND功能的方法。分享给大家供大家参考,具体如下:
看到最近都在做自定义的东西,因为比较灵活,还可以摆脱系统自身不怎么漂亮的UI,(大家都懂得)所以自己也做了下自定义的分享列表,用PopupWindow的方式弹出。
先上效果图:
1、布局:
popup_share.xml

<? xml
version = "1.0"
encoding = "utf-8" ?>
android:layout_width = "fill_parent"
android:layout_height = "wrap_content"
>
< ListView
android:id = "@+id/share_list"
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 >

<? xml
version = "1.0"
encoding = "utf-8" ?>
android:gravity = "center_vertical"
android:layout_width = "wrap_content"
android:layout_height = "wrap_content"
android:padding = "2.0dip"
>
< ImageView
android:id = "@+id/share_item_icon"
android:layout_width = "32.0dip"
android:layout_height = "32.0dip"
android:layout_marginLeft = "3.0dip"
android:scaleType = "fitXY"
/>
< TextView
android:id = "@+id/share_item_name"
android:gravity = "center"
android:layout_width = "wrap_content"
android:layout_height = "wrap_content"
android:text = "分享"
android:textColor = "@color/white"
android:singleLine = "true"
android:textSize = "@dimen/s_size"
android:layout_marginLeft = "3.0dip"
android:layout_marginRight = "3.0dip"
/>
</ LinearLayout >

2、查询手机内所有支持分享的应用列表

public
List<ResolveInfo> getShareApps(Context context) {
List<ResolveInfo>
mApps = new
ArrayList<ResolveInfo>();
Intent
intent = new
Intent(Intent.ACTION_SEND, null );
intent.addCategory(Intent.CATEGORY_DEFAULT);
intent.setType( "text/plain" );
//
intent.setType("*/*");
PackageManager
pManager = context.getPackageManager();
mApps
= pManager.queryIntentActivities(intent,
PackageManager.COMPONENT_ENABLED_STATE_DEFAULT);
return
mApps;
}
|
注:ApplicationInfo是从一个特定的应用得到的信息。这些信息是从相对应的Androdimanifest.xml的< application>标签中收集到的。
ResolveInfo这个类是通过解析一个与IntentFilter相对应的intent得到的信息。它部分地对应于从AndroidManifest.xml的< intent>标签收集到的信息。
得到List列表,我自建的AppInfo类,自己建一个就行

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();
appInfo.setAppPkgName(resolveInfo.activityInfo.packageName);
//
showLog_I(TAG, "pkg>" + resolveInfo.activityInfo.packageName + ";name>" + resolveInfo.activityInfo.name);
appInfo.setAppLauncherClassName(resolveInfo.activityInfo.name);
appInfo.setAppName(resolveInfo.loadLabel(packageManager).toString());
appInfo.setAppIcon(resolveInfo.loadIcon(packageManager));
shareAppInfos.add(appInfo);
}
}
return
shareAppInfos;
}

void
initSharePopupWindow(View parent) {
PopupWindow
sharePopupWindow = null ;
View
view = null ;
ListView
shareList = null ;
if ( null
== sharePopupWindow) {
//加载布局文件
view
= LayoutInflater.from(DetailExchangeActivity. this ).inflate(R.layout.popup_share,
null );
shareList
= (ListView) view.findViewById(R.id.share_list);
List<AppInfo>
shareAppInfos = getShareAppList();
final
ShareCustomAdapter adapter = new
ShareCustomAdapter(mContext, shareAppInfos);
shareList.setAdapter(adapter);
shareList.setOnItemClickListener( new
OnItemClickListener() {
@Override
public
void
onItemClick(AdapterView<?> parent, View view,
int
position, long
id) {
//
TODO Auto-generated method stub
Intent
shareIntent = new
Intent(Intent.ACTION_SEND);
AppInfo
appInfo = (AppInfo) adapter.getItem(position);
shareIntent.setComponent( new
ComponentName(appInfo.getAppPkgName(), appInfo.getAppLauncherClassName()));
shareIntent.setType( "text/plain" );
//
shareIntent.setType("*/*");
//这里就是组织内容了,
shareIntent.putExtra(Intent.EXTRA_TEXT,
"测试,这里发送推广地址" );
shareIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
DetailExchangeActivity. this .startActivity(shareIntent);
}
});
sharePopupWindow
= new
PopupWindow(view,
( int )( 160
* density), LinearLayout.LayoutParams.WRAP_CONTENT);
}
//使其聚焦
sharePopupWindow.setFocusable( true );
//设置允许在外点击消失
sharePopupWindow.setOutsideTouchable( true );
//
这个是为了点击“返回Back”也能使其消失,并且并不会影响你的背景
sharePopupWindow.setBackgroundDrawable( new
BitmapDrawable());
//xoff,yoff基于anchor的左下角进行偏移。正数表示下方右边,负数表示(上方左边)
//showAsDropDown(parent,
xPos, yPos);
sharePopupWindow.showAsDropDown(parent,
- 5 ,
5 );
}

注:ShareCustomAdapter自己建一个就行了。(有一个图标和一个分享的名)
