Scrollable and Clickable textview inside gridview android

Question

I have a grid view inwhich I inflate two layouts one with {background imageview containing a imageview and two textviews aligned vertically over the image} and another layout with {background image containing three textviews aligned vertically over the image}.

I have restricted maximum number of lines in textview. Please suggest how to make the textview scrollable in the gridview and I want the gridview items to be clickable which will navigate to next screen on item click.

I tried to make the scrollable textview working inside the gridview using the requestDisallowInterceptTouchEvent method. But i didn't get the expected result. When the setscrollingmovement() method is used, the textview goes unclickable and so this is also not working.

I am not able to post the scenario as image, as I don't have the enough reputations to post image. Image uploaded in google drive.Please use below link to view the image.

Answer 1

I got it working :-) But partially. I used android:descendantFocusability="blocksDescendants" in the root layout of gridview item's custom layout (inflating layout). The thing is onclick works outside of the textiew.

So, the textview scrolls and clicking outside of the textview somewhere on background image fires grid view's onClickListener()

But not able to trigger gridview's onclicklistener() when clicking on textview. Need to look into this issue.

Used suggestion from the stackoverflow link: Referred Link

Edited: Scrollable and clickable textview in gridview - Got Workaround using onTouchlistener

Setting below ontouch click listener for the textview inside the adapter class for gridview will allow you to scroll text as well as fire onItemClick of GridView.

OnTouchListener aListener = new OnTouchListener() {
                                long startTouchTime = 0;

                                @Override
                                public boolean onTouch(View v,
                                        MotionEvent event) {
                                    switch (event.getAction()) {
                                    case MotionEvent.ACTION_DOWN:
                                        Log.e("ACTION_DOWN",
                                                "ACTION_DOWN, intercept true");
                                        startTouchTime = (System
                                                .currentTimeMillis());
                                        // To scroll the textview set this
                                        textview
                                                .setMovementMethod(new ScrollingMovementMethod());
                                        v.getParent()
                                                .requestDisallowInterceptTouchEvent(
                                                        true);
                                        break;
                                    case MotionEvent.ACTION_UP:
                                        Log.e("ACTION_UP",
                                                "Call onitemclick"
                                                        + ((System
                                                                .currentTimeMillis()) - startTouchTime));

                                        if ((System.currentTimeMillis())
                                                - startTouchTime < 200)
                                         // To call gridview onItemClick here
                                            myGridActivity.myGridView
                                                    .getOnItemClickListener()
                                                    .onItemClick(
                                                            null,
                                                            myGridActivity.myGridView,
                                                            (Integer) imageView
                                                                    .getTag(), // Setting the position here through imageview set tag
                                                            (long) 6767);
                                        break;
                                    }
                                    if (event.getAction() == MotionEvent.ACTION_MOVE) {
                                        Log.e("ACTION_MOVE",
                                                "ACTION_MOVE, intercept true");

                                        v.getParent()
                                                .requestDisallowInterceptTouchEvent(
                                                        true);
                                    } else {
                                        Log.e("Other", "Intercept false");
                                        v.getParent()
                                                .requestDisallowInterceptTouchEvent(
                                                        true);

                                    }
                                    return false;
                                }
                            };

                            textview.setOnTouchListener(aCBInfoListener);

Set android:scrollbars="vertical" for the textview to be scrolled.

Answer 2

Try this:

Properties of your TextView in your layout's xml file:

android:maxLines = "INTEGER"

android:scrollbars = "vertical"

Then use:

yourTextView.setMovementMethod(new ScrollingMovementMethod())

in your code.

It will work fine..

or else you can put the TextView into the ScrollView:

<ScrollView android:layout_width="wrap_content"
    android:layout_height="wrap_content" android:layout_weight="1">
    <TextView android:id="@+id/TextView01" android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Testin testin testing "></TextView>
</ScrollView>
