Question

i create dynamic textviews in an activity with some fields returned by a webservice. When the user wants to edit some data, he is sent to another activity. When he clicks on the “back” button i want to update data in the previous activity but i don’t know the right way to do. I use the onRestart method instead of onResume

here is my code :

My first activity which display data :

public class QueryActivity extends Activity {

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.query);

        new WSData() {
        @Override
        public void onPostExecute(final ArrayList<ArrayList<String>> result) {  int nbTextView = result.size();
            TextView[] textViewArray = new TextView[nbTextView];

            for (int i = 0; i < nbTextView; i++) {

                // Horizontal Layout to have the accountName and a button to
                // edit on the same line
                LinearLayout editLayout = new LinearLayout(
                        QueryActivity.this);
                Button edit = new Button(QueryActivity.this);
                edit.setBackgroundDrawable(getResources().getDrawable(
                        R.drawable.editer));

                editLayout.removeAllViewsInLayout();
                editLayout.setOrientation(LinearLayout.HORIZONTAL);
                dynamicWindow.addView(editLayout,
                        new LinearLayout.LayoutParams(
                                LinearLayout.LayoutParams.FILL_PARENT,
                                LinearLayout.LayoutParams.WRAP_CONTENT));

                textViewArray[i] = new TextView(QueryActivity.this);

                // retrieve every field from the result
                final String accountId = result.get(i).get(0);
                final String accountName = result.get(i).get(1);
                final String phone = result.get(i).get(2);
                final String industry = result.get(i).get(3);
                final String website = result.get(i).get(4);

// display only the accountName
                textViewArray[i].setText(accountName);
                textViewArray[i].setTextColor(0xFFFFFFFF);
                textViewArray[i].setGravity(Gravity.CENTER_VERTICAL);
                textViewArray[i].setVisibility(View.VISIBLE);

                edit.setOnClickListener(new OnClickListener() {
                    @Override
                    public void onClick(View v) {
                        Intent intent = new Intent(QueryActivity.this,
                                EditAccountActivity.class);
                                            startActivity(intent);
                    }
                });
}.execute(sessionName, null, "getAccountInfo"); 
}


@Override
public void onRestart() {
    super.onRestart();

}

my other activity, i want to update my data when i click on “back” :

public class EditAccountActivity extends Activity {                 
back.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
             finish();
            }
    });

Answer 1

When he clicks on the "back" button i want to update data in the previous activity

1- Start Activity 2 using startActivityForResult().

2 override the back key event in 2nd Activity and set the intent and Result_OK

3- get data in onActivityForResult in 1st Activity
