我添加了setHasOptionsMenu(true);在onCreateView上。我想调用onRequestPermissionsResult,但onOptionsItemSelected存在问题。 这是一个片段,如果我使用v4.fragment,它会产生不同的问题。 我将使用import android.app.Fragment;但是requestPermissions想要--Call要求API级别23(当前最小值为16): - 我尝试了一些解决方案。我想只有办法解决api级问题。我该如何解决?
@Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater)
{
menu.add("").setIcon(android.R.drawable.ic_menu_call).setShowAsAction(MenuItem.SHOW_AS_ACTION_ALWAYS);
}
@Override
public boolean onOptionsItemSelected(MenuItem item)
{
if (ContextCompat.checkSelfPermission(getActivity(), Manifest.permission.READ_CONTACTS) != PackageManager.PERMISSION_GRANTED)
{
if (ActivityCompat.shouldShowRequestPermissionRationale(getActivity(), Manifest.permission.READ_CONTACTS))
{
}
else
{
ActivityCompat.requestPermissions(getActivity(), new String[]{Manifest.permission.CALL_PHONE}, MY_PERMISSIONS_REQUEST_READ_CONTACTS);
MenuFragment.this.requestPermissions( new String[]{Manifest.permission.CALL_PHONE}, MY_PERMISSIONS_REQUEST_READ_CONTACTS);
requestPermissions( new String[]{Manifest.permission.CALL_PHONE}, MY_PERMISSIONS_REQUEST_READ_CONTACTS);
}
}
return super.onOptionsItemSelected(item);
}
@Override
public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults)
{
Toast.makeText(getActivity(), "Here", Toast.LENGTH_LONG).show();
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
//AlertDialog.Builder builder = new AlertDialog.Builder(this);

我只添加了targetapi并且它有效。另外,我在这个片段中使用了requestPermissions。
@TargetApi(Build.VERSION_CODES.M)
@Override
public boolean onOptionsItemSelected(MenuItem item)
{
if (ContextCompat.checkSelfPermission(getActivity(), Manifest.permission.READ_CONTACTS) != PackageManager.PERMISSION_GRANTED)
{
if (ActivityCompat.shouldShowRequestPermissionRationale(getActivity(), Manifest.permission.READ_CONTACTS))
{
}
else
{
//ActivityCompat.requestPermissions(getActivity(), new String[]{Manifest.permission.CALL_PHONE}, MY_PERMISSIONS_REQUEST_READ_CONTACTS);
//MenuFragment.requestPermissions( new String[]{Manifest.permission.CALL_PHONE}, MY_PERMISSIONS_REQUEST_READ_CONTACTS);
requestPermissions( new String[]{Manifest.permission.CALL_PHONE}, MY_PERMISSIONS_REQUEST_READ_CONTACTS);
}
}
return super.onOptionsItemSelected(item);
}

当你在Fragment中使用Runtime权限时,使用了requestPermission()而不是AppCompact.requestpermission()。

希望得到这个帮助,如果你这样做,请提起并关闭这个问题。
