Android: show soft keyboard automatically when foc

Question

I'm showing an input box using AlertDialog. The EditText inside the dialog itself is automatically focused when I call AlertDialog.show(), but the soft keyboard is not automatically shown.

How do I make the soft keyboard automatically show when the dialog is shown? (and there is no physical/hardware keyboard). Similar to how when I press the Search button to invoke the global search, the soft keyboard is automatically shown.

Answer 1

I found this example http://android-codes-examples.blogspot.com/2011/11/show-or-hide-soft-keyboard-on-opening.html. Add the following code just before alert.show().

InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
imm.toggleSoftInput(InputMethodManager.SHOW_FORCED,0);

Why this answer - Because above solution will show your keyboard but it will not vanish if you click anywhere other that EditText. So you need to do something to make the keybaord disappear when EditText loses focus.

You can achieve this by doing the following steps:

1. Make the parent view(content view of your activity) clickable and focusable by adding the following attributes

       android:clickable="true" 
       android:focusableInTouchMode="true" 
   

2. Implement a hideKeyboard() method

       public void hideKeyboard(View view) {
           InputMethodManager inputMethodManager =(InputMethodManager)getSystemService(Activity.INPUT_METHOD_SERVICE);
           inputMethodManager.hideSoftInputFromWindow(view.getWindowToken(),InputMethodManager.HIDE_IMPLICIT_ONLY );
       }
   

3. Lastly, set the onFocusChangeListener of your edittext.

       edittext.setOnFocusChangeListener(new View.OnFocusChangeListener() {
           @Override
           public void onFocusChange(View v, boolean hasFocus) {
               if (!hasFocus) {
                   hideKeyboard(v);
               }
           }
       });
   

Answer 3

For showing keyboard use:

InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
imm.toggleSoftInput(InputMethodManager.SHOW_FORCED,0);

For hiding keyboard use:

InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
imm.hideSoftInputFromWindow(view.getWindowToken(),0);

I had the same problem and solved it with the following code. I'm not sure how it will behave on a phone with hardware keyboard.

// TextEdit
final EditText textEdit = new EditText(this);

// Builder
AlertDialog.Builder alert = new AlertDialog.Builder(this);
alert.setTitle("Enter text");
alert.setView(textEdit);

alert.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
    @Override
    public void onClick(DialogInterface dialog, int which) {
        String text = textEdit.getText().toString();
        finish();
    }
});

alert.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
    @Override
    public void onClick(DialogInterface dialog, int which) {
        finish();
    }
});

// Dialog
AlertDialog dialog = alert.create();
dialog.setOnShowListener(new OnShowListener() {

    @Override
    public void onShow(DialogInterface dialog) {
        InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
        imm.showSoftInput(textEdit, InputMethodManager.SHOW_IMPLICIT);
    }
});

dialog.show();

Answer 5

Take a look at this discussion which handles manually hiding and showing the IME. However, my feeling is that if a focused EditText is not bringing the IME up it is because you are calling AlertDialog.show() in your OnCreate() or some other method which is evoked before the screen is actually presented. Moving it to OnPostResume() should fix it in that case I believe.

Answer 6

getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_VISIBLE);

I call this in onCreate() to show keyboard automatically, when I came in the Activity.
