Why doesn't the softKeyboard open when I tap an editText inside a ViewPager?

问题

Like the title says, I've got a viewPager with some editText fields inside. I can select the editText fields perfectly fine (emulator and physical device). I see the cursor, and I see the underline color change, indicating it's selected, but I can't type. Tapping on the editText fields doesn't open the softKeyboard.

Is this a known issue with a simple fix, or is code needed to identify what's going wrong here?

Finally bumped in to an answer that's working for me, which can be found here.

Basically, if you're using the onCreateDialog() method, you leave that as is, and add the onResume() method below to your DialogFragment's java file.

@Override
public void onResume() {
    super.onResume();
    Dialog dialog = getDialog();
    dialog.getWindow().clearFlags(WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE | WindowManager.LayoutParams.FLAG_ALT_FOCUSABLE_IM);
    dialog.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_VISIBLE);
}

You can force softKeyboard with this code:

EditText yourEditText= (EditText) findViewById(R.id.yourEditText);
InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
imm.showSoftInput(yourEditText, InputMethodManager.SHOW_IMPLICIT);
