        </LinearLayout>
    </ScrollView>

but not working for me.... main scrollbar working

回答1:

This problem is a little complicated and I don't have enough time to explain, but you can easily get rid of it by adding these onTouch classes at the end of onCreat class or onCreatView class (if you are using fragment).

scrollview1.setOnTouchListener(new OnTouchListener() {

            @Override
            public boolean onTouch(View v, MotionEvent event) {

                tv_desc.getParent().requestDisallowInterceptTouchEvent(false);

                return false;
            }
        });

tv_desc.setOnTouchListener(new OnTouchListener() {

            @Override
            public boolean onTouch(View v, MotionEvent event) {

                tv_desc.getParent().requestDisallowInterceptTouchEvent(true);

                return false;
            }
        });

and also for other textviews.



回答2:

Just set the

android:maxLines = "AN_INTEGER"

android:scrollbars = "vertical"

properties of your TextView in your layout's xml file.

Then use:

tv_desc.setMovementMethod(new ScrollingMovementMethod());


scrollview.setOnTouchListener(new OnTouchListener() { 

        @Override
        public boolean onTouch(View v, MotionEvent event) {

            tv_desc.getParent().requestDisallowInterceptTouchEvent(false);

            return false;
        }
    });

tv_desc.setOnTouchListener(new OnTouchListener() {

        @Override
        public boolean onTouch(View v, MotionEvent event) {

            tv_desc.getParent().requestDisallowInterceptTouchEvent(true);

            return false;
        }
    });

Hope it will work



回答3:

You can also simply add a little elevation to the textView.

    <TextView
        android:id="@+id/tv_composer"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:elevation="1dp"
        android:layout_below="@+id/textView3"
        android:text="Small Text"
        android:textAppearance="?android:attr/textAppearanceSmall"
        android:textColor="@color/black" />

It did the trick for me. :)
