Android获取分享应用列表详解及实例
如果在应用的AndroidManifest.xml中含有 ACTION_SEND 属性，那就证明该应用可以供第三方应用进行调用分享，那怎么获取函数该属性的分享列表了，这对我们做应用的非常有用；最近在做该功能，自己也做了下自定义的分享列表，用PopupWindow的方式弹出。
1、布局:
popup_share.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
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>
popup_share_item.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
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;
}
3、弹出PopupWindow的实现
private 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, "test");
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。(显示会有一个图标和一个分享的名字)
