如何将字符串数据从活动传递到片段? [英] how to pass string data from activity to fragment?

问题描述

我想将字符串值从活动传递到片段.为此，我使用捆绑软件来传输字符串值.

I want to pass string value from activity to fragment. For that I'm using bundle for transferring string value.

输入STRING活动 传递字符串值:-

           Bundle bundle = new Bundle();
            bundle.putString("Value", resultp.get(CurrentProjectActivity.VALUE));
            Log.d(TAG, "Value  ::: " + resultp.get(CurrentProjectActivity.VALUE));
            // set Fragmentclass Arguments
            AmenetiesFragment fragobj = new AmenetiesFragment();
            fragobj.setArguments(bundle);

在日志中，我也获得了值"值.

In log I got "Value" value as well.

获取片段中的字符串值(不起作用).

GET STRING VALUE IN FRAGMENT (IT IS NOT WORKING).

     @Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {

    View rootView = inflater.inflate(R.layout.activity_listview, container, false);
    Bundle bundle = this.getArguments();
    Log.d(TAG, "Value's value:)  ::: " + bundle);
    String strtext = bundle.getString("Value");
    return rootView;
}

在日志中，我得到BUNDLE的NULL值.请帮助我解决此问题.预先感谢.

In log I'm getting NULL value for BUNDLE. Please help me to resolve this Issue. Thanks in advance.

推荐答案

我建议您遵循以下此.您应该使用界面.在此处

I advice you to follow this link1 and this . You should use interface. Check here

Bundle bundle = new Bundle();
bundle.putString("edttext", "From Activity");
// set Fragmentclass Arguments
Fragmentclass fragobj = new Fragmentclass();
fragobj.setArguments(bundle);

以及Frament任务

and in the Frament task

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
    String strtext = getArguments().getString("edttext");    
    return inflater.inflate(R.layout.fragment, container, false);
}
