方法1: 简单但有时会无效
InputMethodManager manager= (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE); 
@Override 
public boolean onTouchEvent(MotionEvent event) {   
// TODO Auto-generated method stub  
if(event.getAction() == MotionEvent.ACTION_DOWN){    
if(getCurrentFocus()!=null&& getCurrentFocus().getWindowToken()!=null){     
manager.hideSoftInputFromWindow(getCurrentFocus().getWindowToken(), InputMethodManager.HIDE_NOT_ALWAYS);    
}   
}   
return super.onTouchEvent(event);  
}
 
方法2: 完美适用activity与fragment
 
// -------------------------------------隐藏输入法-----------------------------------------------------
    // 获取点击事件
    @Override
    publicbooleandispatchTouchEvent(MotionEvent ev) {
        // TODO Auto-generated method stub
        if(ev.getAction() == MotionEvent.ACTION_DOWN) {
            View view = getCurrentFocus();
            if(isHideInput(view, ev)) {
                HideSoftInput(view.getWindowToken());
            }
        }
        returnsuper.dispatchTouchEvent(ev);
    }
    // 判定是否需要隐藏
    privatebooleanisHideInput(View v, MotionEvent ev) {
        if(v !=null && (v instanceof EditText)) {
            int[] l = {0,0};
            v.getLocationInWindow(l);
            intleft = l[0], top = l[1], bottom = top + v.getHeight(), right = left
                    + v.getWidth();
            if(ev.getX() > left && ev.getX() < right && ev.getY() > top
                    && ev.getY() < bottom) {
                returnfalse;
            }else{
                returntrue;
            }
        }
        returnfalse;
    }
    // 隐藏软键盘
    privatevoidHideSoftInput(IBinder token) {
        if(token !=null) {
            InputMethodManager manager = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
            manager.hideSoftInputFromWindow(token,
                    InputMethodManager.HIDE_NOT_ALWAYS);
        }
    }
