如何从列表视图从一个片段发送到另一个数据

瓦伦丁Gjorgoski：

我有一对夫妇的ListView项目时，我就特别列表视图点击进入Fragment_2与被点击的ListView的价值，我需要。我尝试下面的Fragment_1我得到了适当的值就显示Tosat通知代码，但在Fragment_2束总是空。

在Fragment_1 onCreate方法

listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            public void onItemClick(AdapterView<?> parent, View view,
                                    int position, long id) {
                String value = ((TextView) view.findViewById(R.id.username)).getText().toString();
                MainFragment fragment = new MainFragment ();
                Bundle bundle = new Bundle();
                bundle.putString("view", value);
                Toast.makeText(getApplicationContext(), value, Toast.LENGTH_SHORT).show();
                fragment.setArguments(bundle);

在Fragment_2 onCreate方法

 Bundle bundle = this.getArguments();
        if (bundle != null) {
            String myString = bundle.getString("view");
            Toast.makeText(getContext(), myString, Toast.LENGTH_SHORT).show();

UDPATE：

listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            public void onItemClick(AdapterView<?> parent, View view,
                                    int position, long id) {
                String value = ((TextView) view.findViewById(R.id.username)).getText().toString();
                MainFragment fragment = new MainFragment ();
                Bundle bundle = new Bundle();
                bundle.putString("view", value);
                Toast.makeText(getApplicationContext(), value, Toast.LENGTH_SHORT).show();
                fragment.setArguments(bundle);

                if (position == 0) {
                    Intent myIntent = new Intent(view.getContext(), MainActivity.class);
                    startActivityForResult(myIntent, 0);

                }

                if (position == 1) {
                    Intent myIntent = new Intent(view.getContext(), MainActivity.class);
                    startActivityForResult(myIntent, 0);
                }

                if (position == 2) {
                    Intent myIntent = new Intent(view.getContext(), MainActivity.class);
                    startActivityForResult(myIntent, 0);
                }

                if (position == 3) {
                    Intent myIntent = new Intent(view.getContext(), MainActivity.class);
                    startActivityForResult(myIntent, 0);
                }

                            // ETC .......
            }
        });

只需更换下面的代码onItemClick方法。

            String value = ((TextView) 
            view.findViewById(R.id.username)).getText().toString();
            Bundle bundle = new Bundle();
            bundle.putString("view", value);
            Intent myIntent = new Intent(view.getContext(), MainActivity.class);
            myIntent.putExtra(bundle);
            startActivityForResult(myIntent, 0);

在MainActivity更换您MainFragment这样，

            MainFragment fragment = new MainFragment ();
            fragment.setArguments(getIntent().getExtras());

            getSupportFragmentManager()
              .beginTransaction()
              .replace("your fragment container id here", fragment)
              .commit();
