        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="12"
        android:ellipsize="middle"
        android:gravity="center"
        android:textColor="#FFFFFF"
        android:clickable="true"
        android:textIsSelectable="true"
        android:textColorHighlight="#fffffe60"
        style="@android:style/Holo.ButtonBar"

        android:layout_gravity="center" 
        android:textSize="15sp"/>

    private  TextViewSelectable subtitleText;
 subtitleText =          (TextViewSelectable)findViewById(R.id.offLine_subtitleText);
  subtitleText.setOnSelectionChangedListener(this);

Answer 1

You can't, not entirely. Even if you block all those, if you use a keyboard such as swipe you can access copy and paste via the keyboard (swype key to c and swype key to v gestures), which does NOT use any of that functionality and can't be blocked.

Answer 2

give below property in the edittext in your layout

android:longClickable="false"
