Selected TextView not working

Question

Despite the fact that I managed to create marquee TextView, because I followed the textbook, and it works correctly, when I tried to do another one TextViewin another activity like marquee, it did not work. I took the exact step accurately, but to no avail. what do you think I'm missing?

Update

I think the problem is the focuspresentation, because I checked if it has TextViewfocus even after the call imgPathTv.setSelected(true), and as a result, it has no focus.

Updated_Code

String imgPath = dataBaseRow.getImgPath();
    if (imgPath.equals("")) {
        Log.d(TAG, "@createInfoReport(): dataBaseRow.getImgPath() Returns NULL");
        imgPathTv.setText("NULL");
    }else {
        Log.d(TAG, "@createInfoReport(): dataBaseRow.getImgPath() Has Value");

            imgPathTv.setSelected(true);
            imgPathTv.setText(imgPath);

            if(imgPathTv.findFocus() != null) {
                Toast.makeText(getApplicationContext(), "there is a View has the Focus", Toast.LENGTH_SHORT).show();
            }else
                Toast.makeText(getApplicationContext(), "NO View has the Focus", Toast.LENGTH_SHORT).show();
    }

Java_Code:

    TextView imgPathTv = (TextView) mDialog.findViewById(R.id.imgPathValue);
    Log.i(TAG, "@createInfoReport(): imgPathTv IS IN FOCUS");
    imgPathTv.setSelected(true);

TextView_xml:

<TextView 
                    android:id="@+id/imgPathValue"
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:singleLine="true"
                    android:ellipsize="marquee"
                    android:marqueeRepeatLimit="marquee_forever"
                    android:scrollHorizontally="true"
                    android:focusable="true"
                    android:focusableInTouchMode="true"
                    android:fadingEdge="horizontal"/>
