java - onTouchListener with ViewFlipper doesn't work immediately -
i have created activity using scrollview. inside scrollview have created linearlayout viewflipper of 2 children layouts , have set viewflipper "invisible". before viewflipper have 2 buttons , want set application load right child of viewflipper depending on button user pressed. viewflipper's children layouts buttons. made them add id in array when pressed , want let them in pressed status until user press them again in order release them. have done it, have faced 2 problems:
1) when pressing button, viewflipper draws relative layout, ontouchlistener doesn't work until press other button , viewflipper draw other layout. looks working correctly when changing layouts. know how make work instantly without switching between layouts?
2) ontouchlistener doesn't work totally right. mean, want set button.setpressed(true) or false if has been set true, looks random if work correctly. sometimes, press button , nothing happens , after few seconds try again , works fine. know how can solve or has suggest better way make buttons stay pressed?
my activity xml file is:
<linearlayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:gravity="center_horizontal" android:orientation="vertical" > <scrollview android:id="@+id/scrollview" android:layout_width="match_parent" android:layout_height="wrap_content" > <linearlayout android:id="@+id/formlayout" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center_horizontal" android:orientation="vertical" > <textview android:id="@+id/selecttxt" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center_horizontal" android:text="select option" /> <linearlayout android:id="@+id/choosebuttons" android:layout_width="wrap_content" android:layout_height="120dp" android:layout_margintop="10dp" android:layout_marginbottom="10dp" android:layout_gravity="center_horizontal" android:orientation="horizontal" > <button android:id="@+id/firstbtn" android:layout_width="120dp" android:layout_height="fill_parent" android:layout_marginbottom="1dp" android:layout_margintop="2dp" android:layout_marginright="5dp" android:text="option 1" android:textcolor="@android:color/white" android:background="@drawable/option1"/> <button android:id="@+id/secondbtn" android:layout_width="120dp" android:layout_height="fill_parent" android:layout_marginbottom="1dp" android:layout_margintop="2dp" android:layout_marginleft="5dp" android:text="option 2" android:textcolor="@android:color/white" android:background="@drawable/option2"/> </linearlayout> <textview android:id="@+id/subchoices" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_margintop="10dp" android:layout_marginbottom="20dp" android:layout_gravity="center_horizontal" android:text="select 5 options" /> <viewflipper android:id="@+id/optionsflipper" android:layout_width="wrap_content" android:layout_height="wrap_content" android:visibility="invisible"> <include android:id="@+id/include1" layout="@layout/option1layout" /> <include android:id="@+id/include2" layout="@layout/option2layout" /> </viewflipper> <button android:id="@+id/okbtn" android:text="ok" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center_horizontal" android:layout_margintop="10dp"/> </linearlayout> </scrollview> here java code:

i finally, used fragments instead of viewflipper , togglebuttons instead of simple buttons , worked fine!
