How to force keyboard to show/hide? [duplicate]

Question

I tried to show keyboard after I inflate LinearLayout and call setContentView like:

InputMethodManager mgr = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
mgr.showSoftInput(etContent, InputMethodManager.SHOW_FORCED);
getContent.requestFocus();

It didn't work. I also tried this:

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

But it also didn't work. How can I force the keyboard to show/hide? What did I do wrong?

Answer 1

This should work

public class KeyBoard {

    public static void toggle(Activity activity){
        InputMethodManager imm = (InputMethodManager) activity.getSystemService(Activity.INPUT_METHOD_SERVICE);
        if (imm.isActive()){
            imm.toggleSoftInput(InputMethodManager.HIDE_IMPLICIT_ONLY, 0); // hide
        } else {
            imm.toggleSoftInput(0, InputMethodManager.HIDE_IMPLICIT_ONLY); // show
        }
    }//end method
}//end class

Answer 2

this link is clear about hiding the soft keyboard. to show it you can use a hack - create an EditText anywhere in your layout, layout_width and layout_height=0dip, and in onCreate do

yourEditText.requestFocus();
