                (InputMethodManager) activity.getSystemService(Activity.INPUT_METHOD_SERVICE);
        if (imm == null) return;
        View view = activity.getCurrentFocus();
        if (view == null) view = new View(activity);
        imm.showSoftInput(view, InputMethodManager.SHOW_FORCED);
}

        if (imm == null) return;
        view.setFocusable(true);

                (InputMethodManager) activity.getSystemService(Activity.INPUT_METHOD_SERVICE);
        if (imm == null) return;
        View view = activity.getCurrentFocus();

在BaseActivity中，重写onTouchEvent

public boolean onTouchEvent(MotionEvent event) {
        if(null != this.getCurrentFocus()){
            InputMethodManager mInputMethodManager = (InputMethodManager) getSystemService(INPUT_METHOD_SERVICE);
            return mInputMethodManager.hideSoftInputFromWindow(this.getCurrentFocus().getWindowToken(), 0);
        }
        return super .onTouchEvent(event);
}
