Answer 1

Shilkin's code works great.I make it a little more stronger.Now it handle the situation that the EditText's direct parent is not the ScrollView(eg, EditText is wrapped in LinearLayout before it put into the scrollview).

The method code:

public static void handleEditTextScrollable(EditText editText, final int resId) {
    editText.setOnTouchListener(new View.OnTouchListener() {
        @Override
        public boolean onTouch(View v, MotionEvent event) {
            if (v.getId() == resId) {
                ViewParent parent = v.getParent();
                while (!(parent instanceof ScrollView)) {
                    parent = parent.getParent();
                }
                parent.requestDisallowInterceptTouchEvent(true);

                switch (event.getAction() & MotionEvent.ACTION_MASK) {
                    case MotionEvent.ACTION_UP:
                        parent.requestDisallowInterceptTouchEvent(false);
                        break;
                }
            }
            return false;
        }
    });
}

Call it like this:

handleEditTextScrollable(comment, R.id.wo_task_comments);

One Option is to set the height of the child EditText as the height of the total max lines (max_lines * font_height). So, the internal scroll will be off and the only scroll will be the parent scroll.

Answer 3

Try:

@Override
public void onCreate(Bundle savedInstanceState) {
    .....  
    EditText et = (EditText)findViewById(R.id.wo_task_comments);
    et.setOnTouchListener(this);
    .....
}

@Override
public boolean onTouch(View view, MotionEvent motionEvent) {
    if(view.getId() == R.id.wo_task_comments){
        view.getParent().requestDisallowInterceptTouchEvent(true);
        switch (motionEvent.getAction() & MotionEvent.ACTION_MASK) {
            case MotionEvent.ACTION_UP:
                view.getParent().requestDisallowInterceptTouchEvent(false);
                break;
        }
    }
    return false;
}

In your case:

public class MyActivity extends Activity  {

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    initComments(findViewById(R.id.YOUR_MAIN_LAYOUT_ID));  
}


public void initComments(final View view) {
    EditText comment = (EditText) view.findViewById(R.id.wo_task_comments);

    comment.setOnTouchListener(new View.OnTouchListener() {

        @Override
        public boolean onTouch(final View v, final MotionEvent motionEvent) {
            if (v.getId() == R.id.wo_task_comments) {
                v.getParent().requestDisallowInterceptTouchEvent(true);
                switch (motionEvent.getAction() & MotionEvent.ACTION_MASK) {
                    case MotionEvent.ACTION_UP:
                        v.getParent().requestDisallowInterceptTouchEvent(
                                false);
                        break;
                }
            }
            return false;
        }
    });

    comment.setText("very very long comment"
            + "very very long comment\n" + "very very long comment\n"
            + "very very long comment\n" + "very very long comment\n"
            + "very very long comment\n" + "very very long comment\n"
            + "very very long comment\n" + "very very long comment\n"
            + "very very long comment\n" + "very very long comment\n"
            + "very very long comment\n" + "very very long comment\n"
            + "very very long comment\n" + "very very long comment\n"
            + "very very long comment\n" + "very very long comment\n"
            + "very very long comment");
}

}
