when using AlertDialog.Builder with EditText, the

问题:

I am using AlertDialog.Builder in order to create an input box, with EditText as the input method.

Unfortunately, the Soft Keyboard doesn't pop, although the EditText is in focus, unless you explicitly touch it again.

Is there a way to force it to pop?

I've tried the following, after the (AlertDialog.Builder).show(); but for no avail.

InputMethodManager mgr = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
mgr.showSoftInput(input, InputMethodManager.SHOW_FORCED);

Anyone can help?

Thanks!!

I've made such a thing

AlertDialog.Builder b = new AlertDialog.Builder(this);//....
AlertDialog dialog = b.create();

dialog.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_VISIBLE);

dialog.show();

I've managed to solve it like this:

Dialog = builder.create();
Dialog.show();
Dialog.getWindow().clearFlags(WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE  | WindowManager.LayoutParams.FLAG_ALT_FOCUSABLE_IM);
Dialog.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_VISIBLE);

I found out that the same code works properly on Tablet, the keyboard does pop up, but on Phone it doesn't, so researching further, seems to point to the "adjust" option.

I am using this, feels much cleaner.

AlertDialog d = builder.create();
d.getWindow().setSoftInputMode(
    WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE);
d.show();

When you call showDialog to show a Dialogue created using AlertDialog in onCreateDialog

You should put the code here

    @Override
protected void onPrepareDialog (int id, Dialog dialog, Bundle args)
{
    TextView editText=(TextView) dialog.findViewById(R....);

    editText.setOnFocusChangeListener(new View.OnFocusChangeListener() {
       @Override
       public void onFocusChange(View v, boolean hasFocus) {
         if (hasFocus) {
            dialog.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_VISIBLE);
         }
       }
    });

}

In my case the only way I was able to show the keyboard when the Dialog was shown was by adding to my DialogFragment:

@Override
public void onResume() {
    super.onResume();
    getDialog().getWindow().clearFlags(WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE | WindowManager.LayoutParams.FLAG_ALT_FOCUSABLE_IM);
    getDialog().getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_VISIBLE);
    myEditText.requestFocus();
}

Note the SOFT_INPUT_STATE_ALWAYS_VISIBLE instead of SOFT_INPUT_STATE_VISIBLE.

From documentation:

int SOFT_INPUT_STATE_ALWAYS_VISIBLE
Visibility state for softInputMode: please always make the soft input area visible when this window receives input focus.

A much better solution is given here.

dialog.getWindow().clearFlags(
         WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE
        |WindowManager.LayoutParams.FLAG_ALT_FOCUSABLE_IM);

No workaround. EditText behaves as expected.

回答7:

Window window = dialog.getWindow();
    window.clearFlags(WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE | WindowManager.LayoutParams.FLAG_ALT_FOCUSABLE_IM);
    window.setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_VISIBLE);

回答8:

This was answered here already. Using an OnFocusChangeListener worked for me.

回答9:

Try this, its working for me

If you want to display soft keyboard:

InputMethodManager imm = (InputMethodManager)getActivity().getSystemService(Context.INPUT_METHOD_SERVICE);
                    imm.showSoftInput(input.getWindowToken(), 0);

And if you want to hide the it:

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

回答10:

final AlertDialog.Builder alert = new AlertDialog.Builder(context);

final AlertDialog dialog = alert.show();
dialog.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_VISIBLE);
