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

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

List<AppInfo> getShareAppList() {

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;
}

View view =

ListView shareList =

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)
