Android调用系统分享，指定某些应用来分享

1、指定某些应用来分享

private void initShareIntent() {

Intent intent = new Intent(Intent.ACTION_SEND);

intent.setType("text/plain");

List<ResolveInfo> resInfo =getPackageManager().queryIntentActivities(

intent, 0);

if (!resInfo.isEmpty()) {

List<Intent> targetedShareIntents = newArrayList<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("com.sina.weibo")

|| activityInfo.name.contains("tencent")) {

targeted.putExtra(Intent.EXTRA_TEXT, "分享内容");

targeted.setPackage(activityInfo.packageName);

targetedShareIntents.add(targeted);

}

}

Intent chooserIntent = Intent.createChooser(

targetedShareIntents.remove(0), "Select app to share");

if (chooserIntent == null) {

return;

}

chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS,

targetedShareIntents.toArray(new Parcelable[]{}));

try {

startActivity(chooserIntent);

} catch (android.content.ActivityNotFoundException ex) {

Toast.makeText(this, "Can't find sharecomponent to share",

Toast.LENGTH_SHORT).show();

}

}

}



2、指定一个应用来分享

private void initShareIntent(String type)
{

boolean found = false;

Intent share = new Intent(android.content.Intent.ACTION_SEND);

share.setType("image/*");

// gets the list of intentsthat can be loaded.

List<ResolveInfo> resInfo =getPackageManager().queryIntentActivities(

share, 0);

if (!resInfo.isEmpty()) {

for (ResolveInfo info : resInfo) {

if (info.activityInfo.packageName.toLowerCase().contains(type)

|| info.activityInfo.name.toLowerCase().contains(type)) {

share.putExtra(Intent.EXTRA_SUBJECT, "subject");

share.putExtra(Intent.EXTRA_TEXT, "your text");

//share.putExtra(Intent.EXTRA_STREAM,

// Uri.fromFile(newFile(myPath))); // Optional, just

// // if you wanna

// // share an

// // image.

share.setPackage(info.activityInfo.packageName);

found = true;

break;

}

}

if (!found)

return;

startActivity(Intent.createChooser(share, "Select"));

}

}

调用方法:

private void initShareIntent(String type) {

boolean found = false;

Intent share = new Intent(android.content.Intent.ACTION_SEND);

share.setType("image/*");

// gets the list of intentsthat can be loaded.

List<ResolveInfo> resInfo =getPackageManager().queryIntentActivities(

share, 0);

if (!resInfo.isEmpty()) {

for (ResolveInfo info : resInfo) {

if (info.activityInfo.packageName.toLowerCase().contains(type)

|| info.activityInfo.name.toLowerCase().contains(type)) {

share.putExtra(Intent.EXTRA_SUBJECT, "subject");

share.putExtra(Intent.EXTRA_TEXT, "your text");

//share.putExtra(Intent.EXTRA_STREAM,

// Uri.fromFile(newFile(myPath))); // Optional, just

// // if you wanna

// // share an

// // image.

share.setPackage(info.activityInfo.packageName);

found = true;

break;

}

}

if (!found)

return;

startActivity(Intent.createChooser(share, "Select"));

}

}
