Android-Android分享中,如何过滤指定的应用,并且对不同的分享方式发送不同的内容?

场景:
页面上有一个分享按钮,通过各种分享方式,分享不同的内容。

一般的方式:

Intent intent = new Intent(Intent.ACTION_SEND);
intent.setType("text/plain");
intent.putExtra(Intent.EXTRA_TITLE, title);
intent.putExtra(Intent.EXTRA_SUBJECT, subject);
intent.putExtra(Intent.EXTRA_TEXT, content);

Intent chooserIntent = Intent.createChooser(intent, "Select app to share");
if (chooserIntent == null) {
return;
}
try {
startActivity(chooserIntent);
} catch (android.content.ActivityNotFoundException ex) {
Toast.makeText(this, "Can't find share component to share", Toast.LENGTH_SHORT).show();
}

终于找到解决方法了。

String contentDetails = "";
String contentBrief = "";
String shareUrl = "";
Intent it = new Intent(Intent.ACTION_SEND);
it.setType("text/plain");
List<ResolveInfo> resInfo = getPackageManager().queryIntentActivities(it, 0);
if (!resInfo.isEmpty()) {
List<Intent> targetedShareIntents = new ArrayList<Intent>();
for (ResolveInfo info : resInfo) {
Intent targeted = new Intent(Intent.ACTION_SEND);
targeted.setType("text/plain");
ActivityInfo activityInfo = info.activityInfo;

// judgments : activityInfo.packageName, activityInfo.name, etc.
if (activityInfo.packageName.contains("bluetooth") || activityInfo.name.contains("bluetooth")) {
continue;
}
if (activityInfo.packageName.contains("gm") || activityInfo.name.contains("mail")) {
targeted.putExtra(Intent.EXTRA_TEXT, contentDetails);
} else if (activityInfo.packageName.contains("zxing")) {
targeted.putExtra(Intent.EXTRA_TEXT, shareUrl);
} else {
targeted.putExtra(Intent.EXTRA_TEXT, contentBrief);
}
targeted.setPackage(activityInfo.packageName);
targetedShareIntents.add(targeted);
}

Intent chooserIntent = Intent.createChooser(targetedShareIntents.remove(0), "Select app to share");
if (chooserIntent == null) {
return;
}

// A Parcelable[] of Intent or LabeledIntent objects as set with
// putExtra(String, Parcelable[]) of additional activities to place
// a the front of the list of choices, when shown to the user with a
// ACTION_CHOOSER.
chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, targetedShareIntents.toArray(new Parcelable[] {}));

try {
startActivity(chooserIntent);
} catch (android.content.ActivityNotFoundException ex) {
Toast.makeText(this, "Can't find share component to share", Toast.LENGTH_SHORT).show();
}
}

过滤掉蓝牙的问题,通过createchooser方式是没有过滤控制权的。只要设置了ACTION_SEND和text/plain的type,那么系统所有支持这两个元素的应用的会被createchooser收集。因此只能自己过滤,使用packagemanager的queryIntentActivities

 Intent sendIntent = new Intent(Intent.ACTION_SEND);
sendIntent.setType("text/plain");
List pkgAppsList = context.getPackageManager().queryIntentActivities( sendIntent, 0);

看一个自己使用listview弹出的例子,在此基础上加上过滤的功能

 package com.commonsware.android.launchalot;

import android.app.ListActivity;
import android.content.ComponentName;
import android.content.Intent;
import android.content.pm.ActivityInfo;
import android.content.pm.PackageManager;
import android.content.pm.ResolveInfo;
import android.os.Bundle;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.ImageView;
import android.widget.ListView;
import android.widget.TextView;
import java.util.Collections;
import java.util.Comparator;
import java.util.List;

public class Launchalot extends ListActivity {
AppAdapter adapter=null;

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);

PackageManager pm=getPackageManager();
Intent main=new Intent(Intent.ACTION_MAIN, null);

main.addCategory(Intent.CATEGORY_LAUNCHER);

List<ResolveInfo> launchables=pm.queryIntentActivities(main, 0);

Collections.sort(launchables,
new ResolveInfo.DisplayNameComparator(pm));

adapter=new AppAdapter(pm, launchables);
setListAdapter(adapter);
}

@Override
protected void onListItemClick(ListView l, View v,
int position, long id) {
ResolveInfo launchable=adapter.getItem(position);
ActivityInfo activity=launchable.activityInfo;
ComponentName name=new ComponentName(activity.applicationInfo.packageName,
activity.name);
Intent i=new Intent(Intent.ACTION_MAIN);

i.addCategory(Intent.CATEGORY_LAUNCHER);
i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK |
Intent.FLAG_ACTIVITY_RESET_TASK_IF_NEEDED);
i.setComponent(name);

startActivity(i);
}

class AppAdapter extends ArrayAdapter<ResolveInfo> {
private PackageManager pm=null;

AppAdapter(PackageManager pm, List<ResolveInfo> apps) {
super(Launchalot.this, R.layout.row, apps);
this.pm=pm;
}

@Override
public View getView(int position, View convertView,
ViewGroup parent) {
if (convertView==null) {
convertView=newView(parent);
}

bindView(position, convertView);

return(convertView);
}

private View newView(ViewGroup parent) {
return(getLayoutInflater().inflate(R.layout.row, parent, false));
}

private void bindView(int position, View row) {
TextView label=(TextView)row.findViewById(R.id.label);

label.setText(getItem(position).loadLabel(pm));

ImageView icon=(ImageView)row.findViewById(R.id.icon);

icon.setImageDrawable(getItem(position).loadIcon(pm));
}
}
}
