dialog – Default Focus and Keyboard to EditText in Android AlertDialog-ThrowExceptions

Exception or error:

I am using the AlertDialog.Builder in Android to quickly prompt the user for text. The dialog shows up and works great, but the user must click on the EditText field to load the soft keyboard. Is there any way to open the keyboard and give focus to the whenever my dialog is opened? Here is my code:

final Map<String,Object> rowData = itemList.get(mPosition);
                    final EditText input = new EditText(searchList.getContext());
                input.requestFocus();


                input.setSingleLine();
                final AlertDialog dialog = new AlertDialog.Builder(searchList.getContext())
                .setTitle(StringUtils.getSafeString(rowData.get("label")))
                .setView(input)
                .setPositiveButton("Ok", new DialogInterface.OnClickListener() {
                    public void onClick(DialogInterface dialog, int whichButton) { 
                        rowData.put("value", StringUtils.getSafeString(input.getText()));
                        searchList.invalidateViews();

                    }
                }).setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
                    public void onClick(DialogInterface dialog, int whichButton) {
                        // Do nothing.
                    }
                }).create();
                dialog.show();
How to solve:

Use the following code. It worked for me.

    editText.setOnFocusChangeListener(new OnFocusChangeListener() {
        @Override
        public void onFocusChange(View v, boolean hasFocus) {
            editText.post(new Runnable() {
                @Override
                public void run() {
                    InputMethodManager inputMethodManager= (InputMethodManager) YourActivity.this.getSystemService(Context.INPUT_METHOD_SERVICE);
                    inputMethodManager.showSoftInput(editText, InputMethodManager.SHOW_IMPLICIT);
                }
            });
        }
    });
    editText.requestFocus();

Hidden keyboard when programmatically setting focus on an EditText in an Android Dialog.

I had this problem as well and it was a pretty simple fix – here is my suggested solution. Although it worked on DialogFragments for me, I see no reason why it wouldn’t work in your case.

Basically the soft keyboard isn’t triggered because the view is being created programmatically. The actual fix was simply putting this line in the onCreateDialog method:

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

From the Android documentation on DialogFragments:

If the user focuses on an EditText, the soft keyboard will
automatically appear. In order to force this to happen with our
programmatic focus, we call
getDialog().getWindow().setSoftInputMode(). Note that many Window
operations you might have done previously in a Dialog can still be
done in a DialogFragment, but you have to call getDialog().getWindow()
instead of just getWindow().

@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {

    //setup your dialog builder and inflate the view you want here
    ...
    //Make sure your EditText has the focus when the dialog is displayed
    edit.requestFocus();
    //Create the dialog and save to a variable, so we can set the keyboard state
    Dialog dialog = builder.create();
    //now, set to show the keyboard automatically
    dialog.getWindow().setSoftInputMode(LayoutParams.SOFT_INPUT_STATE_VISIBLE);
    return dialog;
}

in your XML layout

call

<requestFocus/>

inside your default EditText

<EditText 
android:blabla
....
<requestFocus/>
/>

###

use a custom view if you need it more often

public class RequestFocusEditText extends AppCompatEditText {
    private RequestFocusEditText self;

    public RequestFocusEditText(final Context context, AttributeSet attrs) {
        super(context, attrs);
        this.self = this;

        setOnFocusChangeListener(new OnFocusChangeListener() {
            @Override
            public void onFocusChange(View v, boolean hasFocus) {
                post(new Runnable() {
                    @Override
                    public void run() {
                    InputMethodManager inputMethodManager = (InputMethodManager) context.getSystemService(Context.INPUT_METHOD_SERVICE);
                    inputMethodManager.showSoftInput(self, InputMethodManager.SHOW_IMPLICIT);
                }
            });
        }
    });
    requestFocus();
    }
}

###

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);

or try below code but you must set the requestFocus() or to your edittext

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);
        }
    }
});
