android - 我希望在关闭对话框 fragment 后刷新/重绘 Activity 。我该如何实现？

Question

初看起来是这样的:

这是按下“编辑”时弹出的对话框 fragment ，我希望在关闭对话框 fragment 后在 Activity 中看到更改。

public Dialog onCreateDialog(Bundle savedInstanceState) {
        final View view = getActivity().getLayoutInflater().inflate(R.layout.edit_profile_dialog, new LinearLayout(getActivity()), false);
        editProfile = (EditText) view.findViewById(R.id.changeProfile);
        AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
        setupProgressDialog();
/*get value from Bundle*/
        String editValue = getArguments().getString("value", "");
        editProfile.setText(editValue);
        String title = getArguments().getString("title", "");
        builder.setTitle(title);
        builder.setView(view);
        builder.setCancelable(false);
        builder.setPositiveButton("Ok!", new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which) {
/*edit the value in shared preference*/
                sharedPref = getActivity().getSharedPreferences(getString(R.string.sharedPref), 0);
                editor = sharedPref.edit();
                editor.putString(getArguments().getString("saved", ""), editProfile.getText().toString());
                editor.apply();
               ID= sharedPref.getString("id", null);
                access_token=sharedPref.getString("token",null);
//Start of AsyncTask after this

如果您只需要更新用户从对话框中输入的数据，则不必重绘整个布局。

您只能将用户名设置为相关的 TextView 并关闭对话框 fragment 。

TextView yourNameTextView = (TextView)findViewById(R.id.your_textview);

public void setNameToTextView(String name){
    yourNameTextView.setText(name);
}

当用户点击 Ok 按钮时，您可以调用:

((YourActivity)getActivity).setText(input);

祝你好运。
