fragment之间数据传输的方法

Fragment1

    //发送结果
    private void sendResult(int resultCode, Date date) {
        if (getTargetFragment() == null) {
            return;
        }

        Intent intent = new Intent();
        intent.putExtra("Date", date);

        getTargetFragment().onActivityResult(getTargetRequestCode(), resultCode, intent);
    }

Fragment2

    
    //启动fragment1时设置目标Fragment
    fragemt1.setTargetFragment(Fragment2.this, REQUEST_DATE);
    
    
    //通过重写onActivityResult方法，来接收从fragment1发送的数据
    @Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        if (resultCode != Activity.RESULT_OK) {
            return;
        }

        if (requestCode == REQUEST_DATE) {
            Date date = (Date) data.getSerializableExtra(“Date”);
            test.setDate(date);
        }
        super.onActivityResult(requestCode, resultCode, data);
    }
