EditText with textPassword inputType, but without Softkeyboard

由 非 Y 不嫁゛ 提交于 2019-12-02 07:44:53

So i tried setting InputMethod to null, but this would also disable the textPassword features of replacing password rendering to " * [lastchar]". Is there any other way to disable the softKeyboard from showing up? Uhm just figured it out myself: Simply use: pinInput.setOnClickListener(new OnClickListener() { public void onClick(View v) { InputMethodManager mgr = (InputMethodManager) Pin.this.getSystemService(Context.INPUT_METHOD_SERVICE); mgr

How to know, from addTextChangedListener, how the text has changed

The website developers.android.com says this is from incorrectly converting a string to an integer, but I don't understand how I could be incorrectly getting the data from the EditText . This is my code... public class UserPref2Activity extends Activity { @Override public void onCreate(Bundle savedInstanceState) {
