1、布局:
popup_share.xml
01 |
<?xml version="1.0" encoding="utf-8"?>
|
02 |
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" |
03 |
android:layout_width="fill_parent" |
04 |
android:layout_height="wrap_content" >
|
06 |
android:id="@+id/share_list" |
07 |
android:background="#2F4F4F" |
08 |
android:fadingEdge="none" |
09 |
android:layout_width="fill_parent" |
10 |
android:layout_height="wrap_content" |
11 |
android:cacheColorHint="#00000000" |
12 |
android:divider="#E2DD75" |
13 |
android:dividerHeight="1.0dip" |
14 |
android:headerDividersEnabled="true" |
15 |
android:footerDividersEnabled="false" />
|
popup_share_item.xml
01 |
<?xml version="1.0" encoding="utf-8"?>
|
02 |
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" |
03 |
android:gravity="center_vertical" |
04 |
android:layout_width="wrap_content" |
05 |
android:layout_height="wrap_content" |
06 |
android:padding="2.0dip" >
|
08 |
android:id="@+id/share_item_icon" |
09 |
android:layout_width="32.0dip" |
10 |
android:layout_height="32.0dip" |
11 |
android:layout_marginLeft="3.0dip" |
12 |
android:scaleType="fitXY" />
|
14 |
android:id="@+id/share_item_name" |
15 |
android:gravity="center" |
16 |
android:layout_width="wrap_content" |
17 |
android:layout_height="wrap_content" |
19 |
android:textColor="@color/white" |
20 |
android:singleLine="true" |
21 |
android:textSize="@dimen/s_size" |
22 |
android:layout_marginLeft="3.0dip" |
23 |
android:layout_marginRight="3.0dip" />
|
2、查询手机内所有支持分享的应用列表
01 |
public List<ResolveInfo> getShareApps(Context context) {
|
02 |
List<ResolveInfo> mApps = new ArrayList<ResolveInfo>();
|
03 |
Intent intent = new Intent(Intent.ACTION_SEND, null);
|
04 |
intent.addCategory(Intent.CATEGORY_DEFAULT);
|
05 |
intent.setType("text/plain");
|
06 |
// intent.setType("*/*"); |
07 |
PackageManager pManager = context.getPackageManager();
|
08 |
mApps = pManager.queryIntentActivities(intent,
|
09 |
PackageManager.COMPONENT_ENABLED_STATE_DEFAULT);
|
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
01 |
private List<AppInfo> getShareAppList() {
|
02 |
List<AppInfo> shareAppInfos = new ArrayList<AppInfo>();
|
03 |
PackageManager packageManager = getPackageManager();
|
04 |
List<ResolveInfo> resolveInfos = getShareApps(mContext);
|
05 |
if (null == resolveInfos) {
|
08 |
for (ResolveInfo resolveInfo : resolveInfos) {
|
09 |
AppInfo appInfo = new AppInfo();
|
10 |
appInfo.setAppPkgName(resolveInfo.activityInfo.packageName);
|
11 |
// showLog_I(TAG, "pkg>" + resolveInfo.activityInfo.packageName + ";name>" + resolveInfo.activityInfo.name); |
12 |
appInfo.setAppLauncherClassName(resolveInfo.activityInfo.name);
|
13 |
appInfo.setAppName(resolveInfo.loadLabel(packageManager).toString());
|
14 |
appInfo.setAppIcon(resolveInfo.loadIcon(packageManager));
|
15 |
shareAppInfos.add(appInfo);
|
3、弹出PopupWindow的实现
01 |
private void initSharePopupWindow(View parent) {
|
02 |
PopupWindow sharePopupWindow = null;
|
04 |
ListView shareList = null;
|
05 |
if(null == sharePopupWindow) {
|
07 |
view = LayoutInflater.from(DetailExchangeActivity.this).inflate(R.layout.popup_share, null);
|
08 |
shareList = (ListView) view.findViewById(R.id.share_list);
|
09 |
List<AppInfo> shareAppInfos = getShareAppList();
|
10 |
final ShareCustomAdapter adapter = new ShareCustomAdapter(mContext, shareAppInfos);
|
11 |
shareList.setAdapter(adapter);
|
13 |
shareList.setOnItemClickListener(new OnItemClickListener() {
|
16 |
public void onItemClick(AdapterView<?> parent, View view,
|
17 |
int position, long id) {
|
18 |
// TODO Auto-generated method stub
|
19 |
Intent shareIntent = new Intent(Intent.ACTION_SEND);
|
20 |
AppInfo appInfo = (AppInfo) adapter.getItem(position);
|
21 |
shareIntent.setComponent(new ComponentName(appInfo.getAppPkgName(), appInfo.getAppLauncherClassName()));
|
22 |
shareIntent.setType("text/plain");
|
23 |
// shareIntent.setType("*/*"); |
25 |
shareIntent.putExtra(Intent.EXTRA_TEXT, "测试,这里发送推广地址");
|
26 |
shareIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
|
27 |
DetailExchangeActivity.this.startActivity(shareIntent);
|
31 |
sharePopupWindow = new PopupWindow(view,
|
32 |
(int)(160 * density), LinearLayout.LayoutParams.WRAP_CONTENT);
|
35 |
sharePopupWindow.setFocusable(true);
|
37 |
sharePopupWindow.setOutsideTouchable(true);
|
38 |
// 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
|
39 |
sharePopupWindow.setBackgroundDrawable(new BitmapDrawable());
|
40 |
//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)
|
41 |
//showAsDropDown(parent, xPos, yPos);
|
42 |
sharePopupWindow.showAsDropDown(parent, -5, 5);
|
