java - DraggableView in android -


i using github library of draggablepanel found here. 

<com.github.pedrovgs.draggableview xmlns:android="http://schemas.android.com/apk/res/android"             xmlns:draggable_view="http://schemas.android.com/apk/res-auto"             android:id="@+id/draggable_view"             android:layout_width="match_parent"             android:layout_height="match_parent"             android:gravity="bottom"             draggable_view:bottom_view_id="@+id/bottom"             draggable_view:enable_minimized_horizontal_alpha_effect="false"             draggable_view:top_view_height="60dp"             draggable_view:top_view_id="@+id/fullmedia"             draggable_view:top_view_margin_bottom="60dp"             draggable_view:top_view_margin_right="0dp"             draggable_view:top_view_resize="true"             draggable_view:top_view_x_scale_factor="100"             draggable_view:top_view_y_scale_factor="100">  <linearlayout                 android:id="@+id/fullmedia"                 android:layout_width="match_parent"                 android:layout_height="wrap_content"                 android:background="@color/primary_material_light_1"                 android:orientation="vertical"> <-- other staffs here -->  </linearlayout>  <linearlayout                 android:id="@+id/bottom"                 android:layout_width="match_parent"                 android:layout_height="wrap_content"                 android:background="@color/primary_material_light_1"                 android:orientation="vertical"> <-- other staffs here -->  </linearlayout>   </draggableview

it nice library. having short of problems. need add button controls in top view , buttons should respond clicks. in java class using these 2 methods. 

draggableview.setclicktomaximizeenabled(true); draggableview.setclicktominimizeenabled(true);

but know know why buttons on top view not working. can tell me reason? thing notice when minimize/maximize several times or open other fragments the draggable view gradually becomes transparent. why happens ?

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
