android 键盘强制打开网页,Android：强制键盘出现并专注于EditText

在此先感谢您的帮助.

我想在最后或执行以下代码时出现键盘.

// 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);

但键盘仅在触摸editText字段后出现(即用我的手指).有没有办法让我可以在不使用物理触摸的情况下自动显示电路板？

顺便说一句,我知道我如何指定宽度和高度并不是正确的做事方式.
