How can I preserve the keyboard visibility state upon rotation - if it was hidden before rotation then don't present it

问题 I set up a preferenceScreen to edit the settings in my application. I would like to insert an EditTextPreference that contains a Title like "set your name" and a summary containing the name entered. Is that possible? thank you in advance! 回答1: Sure, here is a short example: EditTextPreference etp = (EditTextPreference) findPreference("the_pref_key"); etp.setSummary("New summary"); This requires that you display your preferences either from a PreferenceActivity or from a PreferenceFragment ,

问题 I have two views using TextInputLayout . The first one is a login view which has only 2 input fields and the second one is a register view which has many input fields.

问题 The EditText view with id="price" has an inputType="numberDecimal" that does not accept any digits but will only accept one decimal point. The other EditText view with id="store" has no inputType set but has two issues. If the view has no input then entering a digit from the keyboard doesn't do anything. The only way to have a digit be accepted is if it immediately follows either a letter or another digit. I am using the default Android keyboard. The layout is being inflated in the
