Android Question

Scrolling EditText inside ScrollView

I have a nasty problem. I have

EditText
(8 lines) inside
ScrollView
. And when I'm trying to scroll text in
EditText
it's behavior is not stable. Sometimes it's scrolling, some times it's not taking focus.

This is my layout file, to make my question more clear:



<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:padding="8dp" >

<TextView
android:id="@+id/wo_task_name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/no_description" />

<TextView
android:id="@+id/wo_task_description"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/no_description" />

<TextView
android:id="@+id/wo_task_comments_label"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="10dp"
android:text="@string/comments" />

<Button
android:id="@+id/wo_task_select_comment"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="@string/select_comment_from_template" />

<EditText
android:id="@+id/wo_task_comments"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="top|left"
android:hint="@string/enter_your_comment_here"
android:lines="8"
android:maxLines="10"
android:minLines="6"
android:scrollbars="vertical"
android:singleLine="false" />
</LinearLayout>




I understand that I'm having this issue because of holding one scrollable control inside another, yet I don't know what to do with this. So, please help me if you can.

Thanks in advance.

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

comment.setOnTouchListener(new OnTouchListener() {

@Override
public boolean onTouch(final View v, final 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;
}
});

comment.setText(currentTask.getComment() + "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");
}


I've tried this, and no result. I'm still unable to scroll my editbox.

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");
}

}
