Get id of TextView in Fragment from FragmentActivity in ViewPager

Question

I'm working with `ViewPager` with 3 `Fragments` and I want to change text of `TextView` in third page. In that page I have a `Button`that when its pressed, go to SD images to select one. When done, returns to page and want to update `TextView` with path of that image. The problem is that when I try to access that `TextView`from `FragmentActivity`it is null. Here is my code SherlockFragmentActivity: ``` public class TabsFacturasActivity extends SherlockFragmentActivity { protected MyApplication myApplication; private static final int FILE_SELECT_CODE = 0; private MyAdapter mAdapter; private ViewPager mPager; private PageIndicator mIndicator; private TextView textViewImg; private int lecturas = 0; private SimpleDateFormat dateFormat = new SimpleDateFormat("dd/MM/yyyy"); private boolean adjunto = false; private String filePath; private boolean esLecturaAT = false; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.fr…

Accepted Answer

You cant access text view from `fragment activity` because its located on `fragment` and your `fragment activity layout` don't have any `text view` with this `id`. You have to access text view from your `third fragment` where you used it in its `layout`. Then access that `object` from your `fragment activity`.

in your fragment do something like this

```
TextView mTextView;
mTextView = (TextView)getView().findViewById(R.id.your_text_view);
```

Create a function like this

```
public void changeText(String mText)
{
mTextView.setText(mText);
}
```

In your activity result

```
//Do not create new object each time you set text. Use the same fragment object which you use for view pager.
        Your_Fragment mFragment;
         protected void onActivityResult(int requestCode, int resultCode, Intent data) {
                switch (requestCode) {
                    case FILE_SELECT_CODE:
                    if (resultCode == RESULT_OK) {

//Set text from here
                mFragment.changeText(imgName);

}
```
