我想支持添加与联络人选取联系人。 看来,READ_CONTACTS许可在特定的手机,而不是其他必需的-见做联系人挑选查询需要取决于Android版本的read_contacts许可?
Intent intent = new Intent(Intent.ACTION_PICK, People.CONTENT_URI);
startActivityForResult(intent, CHOOSE_CONTACT);
发生在onActivityResult()的异常,当我查询返回的数据(mangedQUery())
if (resultCode == Activity.RESULT_OK) {
Uri contactData = data.getData();
if (contactData != null) {
Cursor mCursor = managedQuery(contactData, null, null, null, null);
if (mCursor != null && mCursor.moveToFirst()) {
long id = mCursor.getLong(mCursor.getColumnIndex(People._ID));
String name = mCursor.getString(mCursor.getColumnIndex(People.DISPLAY_NAME));
if (name != null) {
displayName(name);
_contact_id = id;
_contact_name = name.trim();
}
}
}
}
我想知道我怎么能事先检查startActivity会失败,所以不得不这样做“现场检查”之前,我可以禁用该功能。
试图将此作为一个可能的解决方案,但由于ai.permission没有工作总是空:
final PackageManager packageManager = getPackageManager();
final Intent intent = new Intent(Intent.ACTION_PICK, People.CONTENT_URI);
List<ResolveInfo> list = packageManager.queryIntentActivities(intent, PackageManager.MATCH_DEFAULT_ONLY);
for (ResolveInfo resolve : list) {
ActivityInfo ai = resolve.activityInfo;
if (ai.permission != null) {
return false;
}
}
return true;
