Android：强制键盘出现并专注于EditText

Question

Thanks in advance for the help.

I would like a keyboard to appear at the end or during the execution of the following code.

    // edit text
    EditText editText = new EditText(activity);
    editText.setBackgroundColor(Color.WHITE);
    editText.setGravity(Gravity.TOP);
    editText.setText("Type here...");

    RelativeLayout relativeLayoutEditText = new RelativeLayout(activity);
    RelativeLayout.LayoutParams paramRelativeLayoutEditText = new RelativeLayout.LayoutParams(
            LinearLayout.LayoutParams.MATCH_PARENT, 43 * display.getHeight() / 80 );
    paramRelativeLayoutEditText.addRule(RelativeLayout.ALIGN_PARENT_TOP);
    relativeLayoutEditText.addView(editText,paramRelativeLayoutEditText);

    // add all created views to rootView
    rootView.addView(relativeLayoutEditText, paramEditText);

    // open keyboard
    InputMethodManager imm = (InputMethodManager) activity.getSystemService(Context.INPUT_METHOD_SERVICE);
    imm.showSoftInput(editText, InputMethodManager.SHOW_IMPLICIT);

but the keyboard only appears after touching the editText field (ie with my finger). Is there a way that I can make the board automatically appear without using a physical touch?

As an aside I know that how I am specifying the width and height isn't exactly the right way to do things.

Answer 1

Thanks to @Shubham's link I was able to figure it out. The solution was not the answer given in the link, however. It was the second answer.

editText.requestFocus();
InputMethodManager imm = (InputMethodManager) activity.getSystemService(Context.INPUT_METHOD_SERVICE);
imm.toggleSoftInput(InputMethodManager.SHOW_FORCED, InputMethodManager.HIDE_IMPLICIT_ONLY);

Edit:

once using the above solution the keyboard will remain on the screen until a user presses either the back button or the home button (sometimes it takes a few times). To remove the keyboard use this

imm.toggleSoftInputFromWindow(rootView.getWindowToken(), 0,0);

in my case rootView is the rootView of the current activity. I have not tested this to see if this will work on child views.

Answer 2

Add

    editText.requestFocus();

Try this:

EditText editText = (EditText ) findViewById(R.id.myTextViewId);
editText.requestFocus();
InputMethodManager imm = (InputMethodManager)   getSystemService(Context.INPUT_METHOD_SERVICE); 
imm.showSoftInput(editText, InputMethodManager.SHOW_IMPLICIT);

ensure that the edittext is focusable in touch mode. You can do it two way.

In xml:

 android:focusableInTouchMode="true"

in Java:

editText.setFocusableInTouchMode(true);

Answer 3

Try This

EditText textView = (EditText ) findViewById(R.id.myTextViewId);
textView.requestFocus();
InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
imm.showSoftInput(textView, InputMethodManager.SHOW_IMPLICIT);

Answer 4

Possible answer link . Many of the above are also sourced from this link.

Try This :

EditText textView = (EditText )findViewById(R.id.myTextViewId);
textView.requestFocus();    
InputMethodManager imm = 
(InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
imm.showSoftInput(textView, InputMethodManager.SHOW_IMPLICIT);

Answer 5

this will show the keypad

InputMethodManager imm = (InputMethodManager) 
        OrderMainActivity.this.getSystemService(Context.INPUT_METHOD_SERVICE);
imm.showSoftInput(txtCustomerId, InputMethodManager.SHOW_IMPLICIT);

enter your activity name instead of this if you calling keypad from the listeners eg. button click
