Set Focus on EditText

Question

I have an EditText-Field and set an OnFocusChangeListener for it  When it has lost focus  a method is called  which checks the value of the EditText with one in the database  If the return-value of the method is true  a toast is shown and the focus should get back on the EditText again  The focus should always get back on the EditText and the keyboard should show  until the return-value of the method is false   EDIT  I think  I haven t made my real problem perfectly clear yet  No other Item on the Screen should be able to edit  until the value of the EditText is edited to a value  which makes the method  checkLiganame liganame   return false  Only the EditText-Field should be editable   here is my code  which doesn t work for me    final EditText Liganame    EditText  findViewById R id liganame        Liganame setOnFocusChangeListener new OnFocusChangeListener               Override         public void onFocusChange View v  boolean hasFocus                if   hasFocus                     String liganame   Liganame getText   toString                      if  checkLiganame liganame                         Toast toast   Toast makeText CreateTableActivity this                               Dieser Liganame ist bereits vergeben                               Toast LENGTH SHORT                       toast show                        Liganame requestFocus                                      and the method   public boolean checkLiganame String liganame        boolean found   false       DatabaseHelper databaseHelper   new DatabaseHelper this       SQLiteDatabase db   databaseHelper getReadableDatabase         Cursor cursor   db query  liga   new String      liganame                  liganame        liganame        null  null  null  null       Log i  Liganame     String valueOf cursor         db close        if  cursor    null            found   true             return found      This code leads to the following result  After the EditText has lost focus  the focus jumps back to EditText  but I can t edit the text anymore   EDIT2  Changed my code  Scenario   I click on the first EditText and put a String in it  which is already in the database  The toast is showing  Now I can t edit my String anymore  I click  next  on the keyboard and the focus stays on the first EditText  I try to edit my String  but nothing happens  Instead my new String is showing in the second EditText  I click on the back-arrow of my device and reclick on the first and second EditText --  no keyboard is showing   Here is my new Code   public class CreateTableActivity extends Activity implements     OnFocusChangeListener    private EditText Liganame  Mannschaftsanzahl    Override protected void onCreate Bundle savedInstanceState        super onCreate savedInstanceState       setContentView R layout create league        Liganame    EditText  findViewById R id liganame       Liganame setOnFocusChangeListener this       Mannschaftsanzahl    EditText  findViewById R id mannschaftsanzahl       Mannschaftsanzahl setOnFocusChangeListener this        final Button save button    Button  findViewById R id create tabelle speichern button        OnClickListener mCorkyListener   new OnClickListener             public void onClick View v                ButtonClick                         save button setOnClickListener mCorkyListener          Override public void onFocusChange View v  boolean hasFocus        String liganame   Liganame getText   toString         if  checkLiganame liganame             if  Liganame requestFocus                  getWindow                        setSoftInputMode                              WindowManager LayoutParams SOFT INPUT STATE ALWAYS VISIBLE               Mannschaftsanzahl clearFocus                Toast makeText CreateTableActivity this                       Dieser Liganame ist bereits vergeben                       Toast LENGTH SHORT  show

Requesting focus isn t enough to show the keyboard   To get focus and show the keyboard you would write something like this   if myEditText requestFocus          getWindow   setSoftInputMode WindowManager LayoutParams SOFT INPUT STATE ALWAYS VISIBLE       EDIT  Adding extra info to the answer after the checkLiganame method was added   In the checkLiganame method you check if the cursor is null  The cursor will always return an object  so the check for null doesn t do anything  However the problem is in the line db close     When you close the database connection  the Cursor becomes invalid and most probably is nulled   So close the database after you ve fetched the value   Instead of checking the cursor for null  you should check if the number of rows returned are more than 0  if cursor getCount     0  and then set your boolean to true if so   EDIT2  So here s some code for how to make it work  EDIT3  Sorry wrong code I added     S  First off  you need to clear focus if another EditText gets focus  This can be done with myEditText clearFocus    Then in your onFocusChangeListener you shouldn t really care if first EditText has focus or not  so the onFocusChangeListener could look something like this   public class MainActivity extends Activity implements OnFocusChangeListener       private EditText editText1  editText2        Override     protected void onCreate Bundle savedInstanceState            super onCreate savedInstanceState           setContentView R layout activity main            editText1    EditText  findViewById R id editText1           editText1 setOnFocusChangeListener this           editText2    EditText  findViewById R id editText2           editText2 setOnFocusChangeListener this               Override     public void onFocusChange View v  boolean hasFocus            String liganame   editText1 getText   toString             if liganame length      0                if editText1 requestFocus                      getWindow   setSoftInputMode WindowManager LayoutParams SOFT INPUT STATE ALWAYS VISIBLE                   editText2 clearFocus                    Toast makeText MainActivity this   Dieser Liganame ist bereits vergeben   Toast LENGTH SHORT  show                                      Replace the first check if liganame length      0  with your own check  then it should work   Take note  that all the EditText views should have set their onFocusChangeListener to the same listener like I ve done in the example

My answer here  As I read on the official document  I think this is the best answer  just pass the View to parameter such as your EditText  but showSoftKeyboard seems like not working on landscape   private fun showSoftKeyboard view  View        if  view requestFocus              val imm   getSystemService Context INPUT METHOD SERVICE  as InputMethodManager         imm showSoftInput view  InputMethodManager SHOW IMPLICIT           private fun closeSoftKeyboard view  View        if  view requestFocus              val imm   getSystemService Context INPUT METHOD SERVICE  as InputMethodManager         imm hideSoftInputFromWindow view windowToken  InputMethodManager HIDE NOT ALWAYS
