InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
imm.toggleSoftInput(0, InputMethodManager.HIDE_NOT_ALWAYS);
InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE); imm.showSoftInput(view,InputMethodManager.SHOW_FORCED); imm.hideSoftInputFromWindow(view.getWindowToken(), 0); //强制隐藏键盘
mCommentEdittext.setFocusable(true); mCommentEdittext.setFocusableInTouchMode(true); mCommentEdittext.requestFocus(); InputMethodManager inputManager = (InputMethodManager) mCommentEdittext.getContext().getSystemService(Context.INPUT_METHOD_SERVICE); inputManager.showSoftInput(mCommentEdittext, 0);
((InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE)).hideSoftInputFromWindow(WidgetSearchActivity.this.getCurrentFocus().getWindowToken()
, InputMethodManager.HIDE_NOT_ALWAYS);
WidgetSearchActivity是当前的Activity
InputMethodManager imm = (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE); boolean isOpen=imm.isActive();//isOpen若返回true，则表示输入法打开
