我想使用Android Intent.ACTION_SEND快速分享内容。所以我有一个像这样的共享列表:
但我希望为每个操作分享不同的内容,例如:
如果通过电子邮件/ Gmail分享,内容应为“通过电子邮件分享”。
如果通过Facebook分享,内容应为“按Facebook分享”。
那么,是否可以这样做?

您无法获得此类信息。
除非您为活动选择创建自己的对话框实现。
要创建此类对话框,您需要使用PackageManager
及其queryIntentActivities()
功能。该函数返回List<ResolveInfo>
。
ResolveInfo
包含有关活动的一些信息(resolveInfo.activityInfo.packageName
),在PackageManager
的帮助下,您可以获取其他信息(对于在对话框中显示活动非常有用) - 应用程序图标可绘制的,应用标签,......
在对话框(或作为对话框设置样式的活动)的列表中显示结果。单击某个项目时,创建新的Intent.ACTION_SEND,添加所需的内容并添加所选活动的包(intent.setPackage(pkgName)
)。

没有直接的方法来访问这类信息....
步骤1:首先,在代码内部,您需要声明一个适配器,该适配器将包含要在其上共享的列表的自定义视图...
//sharing implementation
Intent sharingIntent = new Intent(android.content.Intent.ACTION_SEND);
// what type of data needs to be send by sharing
sharingIntent.setType("text/plain");
// package names
PackageManager pm = getPackageManager();
// list package
List<ResolveInfo> activityList = pm.queryIntentActivities(sharingIntent, 0);
objShareIntentListAdapter = new ShareIntentListAdapter(CouponView.this,activityList.toArray());
// Create alert dialog box
AlertDialog.Builder builder = new AlertDialog.Builder(v.getContext());
builder.setTitle("Share via");
builder.setAdapter(objShareIntentListAdapter, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int item) {
ResolveInfo info = (ResolveInfo) objShareIntentListAdapter.getItem(item);
// if email shared by user
if(info.activityInfo.packageName.contains("Email")
|| info.activityInfo.packageName.contains("Gmail")
|| info.activityInfo.packageName.contains("Y! Mail")) {
PullShare.makeRequestEmail(COUPONID,CouponType);
}
// start respective activity
Intent intent = new Intent(android.content.Intent.ACTION_SEND);
intent.setClassName(info.activityInfo.packageName, info.activityInfo.name);
intent.setType("text/plain");
intent.putExtra(android.content.Intent.EXTRA_SUBJECT, ShortDesc+" from "+BusinessName);
intent.putExtra(android.content.Intent.EXTRA_TEXT, ShortDesc+" "+shortURL);
intent.putExtra(Intent.EXTRA_TITLE, ShortDesc+" "+shortURL);
((Activity)context).startActivity(intent);
}// end onClick
});
AlertDialog alert = builder.create();
alert.show();
步骤2:现在您已为适配器创建布局inflater(ShareIntentListAdapter.java)
package com.android;
import android.app.Activity;
import android.content.pm.ResolveInfo;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.ImageView;
import android.widget.TextView;
public class ShareIntentListAdapter extends ArrayAdapter{
private final Activity context;
Object[] items;
public ShareIntentListAdapter(Activity context,Object[] items) {
super(context, R.layout.social_share, items);
this.context = context;
this.items = items;
}// end HomeListViewPrototype
@Override
public View getView(int position, View view, ViewGroup parent) {
LayoutInflater inflater = context.getLayoutInflater();
View rowView = inflater.inflate(R.layout.social_share, null, true);
// set share name
TextView shareName = (TextView) rowView.findViewById(R.id.shareName);
// Set share image
ImageView imageShare = (ImageView) rowView.findViewById(R.id.shareImage);
// set native name of App to share
shareName.setText(((ResolveInfo)items[position]).activityInfo.applicationInfo.loadLabel(context.getPackageManager()).toString());
// share native image of the App to share
imageShare.setImageDrawable(((ResolveInfo)items[position]).activityInfo.applicationInfo.loadIcon(context.getPackageManager()));
return rowView;
}// end getView
}// end main onCreate
步骤3:创建xml布局类型以在对话框(social_share.xml)中显示列表视图
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/categoryCell"
android:layout_width="match_parent"
android:layout_height="30dip"
android:background="@android:color/white" >
<TextView
android:id="@+id/shareName"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:layout_marginBottom="15dp"
android:layout_marginLeft="5dp"
android:layout_marginTop="15dp"
android:textAppearance="?android:attr/textAppearanceMedium"
android:textColor="#000000"
android:textStyle="bold" />
<ImageView
android:id="@+id/shareImage"
android:layout_width="35dip"
android:layout_height="35dip"
android:layout_alignParentRight="true"
android:layout_centerVertical="true"
android:contentDescription="@string/image_view" />
</RelativeLayout>

不确定您是否仍在寻找答案,但ClickClickClack有一个示例实现,说明如何拦截ACTION_SEND意图并根据包名称和某些特征选择最终发生的事情。涉及Tomik提到的大多数步骤。

使用Tomik很棒的答案我能够使用PackageManager生成我自己的自定义共享列表 loadLabel和LoadIcon:
public class MainActivity extends FragmentActivity
{
ArrayList<Drawable> icons;
ArrayList<String> labels;
@Override
protected void onCreate(Bundle arg0) {
// TODO Auto-generated method stub
super.onCreate(arg0);
setContentView(R.layout.activity_main);
icons=new ArrayList<Drawable>();
labels=new ArrayList<String>();
PackageManager manager=getPackageManager();
Intent intent = new Intent(Intent.ACTION_SEND);
intent.setType("text/plain");
List<ResolveInfo> activities=manager.
queryIntentActivities(intent,0);
for(int i=0;i<activities.size();i++)
{
ApplicationInfo appInfo=null;
try {
appInfo=manager.getApplicationInfo(activities.get(i).activityInfo.packageName,0);
labels.add(name=appInfo.loadLabel(getPackageManager()).toString());
} catch (NameNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
icons.add(appInfo.loadIcon(getPackageManager()));
}
}
}
