<div class =“post-text”itemprop =“text”> <P> Android marshmallow有新的权限系统。您需要在运行时请求权限。 <a href="http://developer.android.com/training/permissions/requesting.html" rel="noreferrer"> http://developer.android.com/training/permissions/requesting.html </A> 。 </p> <P> 例： </p> <pre> <code> @Override public void onClick(View v) { switch (v.getId()){ case R.id.tv_contact:{ askForContactPermission(); break; } } } private void getContact(){ Intent intent = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI); startActivityForResult(intent, PICK_CONTACT); } public void askForContactPermission(){ if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) { if (ContextCompat.checkSelfPermission(getActivity(),Manifest.permission.READ_CONTACTS) != PackageManager.PERMISSION_GRANTED) { // Should we show an explanation? if (ActivityCompat.shouldShowRequestPermissionRationale(getActivity(), Manifest.permission.READ_CONTACTS)) { AlertDialog.Builder builder = new AlertDialog.Builder(getActivity()); builder.setTitle("Contacts access needed"); builder.setPositiveButton(android.R.string.ok, null); builder.setMessage("please confirm Contacts access");//TODO put real question builder.setOnDismissListener(new DialogInterface.OnDismissListener() { @TargetApi(Build.VERSION_CODES.M) @Override public void onDismiss(DialogInterface dialog) { requestPermissions( new String[] {Manifest.permission.READ_CONTACTS} , PERMISSION_REQUEST_CONTACT); } }); builder.show(); // Show an expanation to the user *asynchronously* -- don't block // this thread waiting for the user's response! After the user // sees the explanation, try again to request the permission. } else { // No explanation needed, we can request the permission. ActivityCompat.requestPermissions(getActivity(), new String[]{Manifest.permission.READ_CONTACTS}, PERMISSION_REQUEST_CONTACT); // MY_PERMISSIONS_REQUEST_READ_CONTACTS is an // app-defined int constant. The callback method gets the // result of the request. } }else{ getContact(); } } else{ getContact(); } } @Override public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) { switch (requestCode) { case PERMISSION_REQUEST_CONTACT: { // If request is cancelled, the result arrays are empty. if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) { getContact(); // permission was granted, yay! Do the // contacts-related task you need to do. } else { ToastMaster.showMessage(getActivity(),"No permission for contacts"); // permission denied, boo! Disable the // functionality that depends on this permission. } return; } // other 'case' lines to check for other // permissions this app might request } } </code> </pre> </DIV>
