first time poster here. although have been shadowing lot lately , decided post today.
i have made android app - first ever - yay! right, displays fine , looks good. works 100% in avd samsung galaxy sii.
the problem not able click anywhere. when click i'm supposed nothing happens. suspect may 1 of layouts being above other layouts preventing me sending click events appropriate controls.
so, did play around layout , doesn't matter how organize them, nothing happens ( no clicking happens )
here layouts in question :
activity_fullscreen_activity_ncc.xml
<framelayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:id="@+id/fullscreen_content_controls" android:layout_width="match_parent" android:layout_height="match_parent" android:background="#ffffff" tools:context=".fullscreenactivityncc" android:clickable="true" android:focusable="true" > <requestfocus /> <!-- primary full-screen view. can replaced whatever view needed present content, e.g. videoview, surfaceview, textureview, etc. --> <!-- framelayout insets children based on system windows using android:fitssystemwindows. --><button android:id="@+id/contact" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="bottom|left" android:text="@string/contact" android:textcolor="#000000" /> <button android:id="@+id/download" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="bottom|right" android:text="@string/download" android:textcolor="#000000" /> <framelayout android:id="@+id/fullscreen_content" android:layout_width="match_parent" android:layout_height="407dp" android:clickable="true" android:focusable="true"> <imageview android:id="@+id/image2" android:layout_width="wrap_content" android:layout_height="wrap_content" android:contentdescription="@string/downloadprogress" /> <include android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center_vertical|center_horizontal" android:layout_marginbottom="50dp" android:layout_margintop="30dp" layout="@layout/literacy" /> <textview android:id="@+id/textview1" android:layout_width="wrap_content" android:layout_height="52dp" android:gravity="center_vertical|center_horizontal" android:text="@string/welcomebrowse" android:textcolor="#000000" /> <textview android:id="@+id/textview2" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_gravity="bottom" android:gravity="center_vertical|center_horizontal" android:text="@string/contactncc" android:textalignment="center" android:textcolor="#ff0000" /> </framelayout> </framelayout> literacy.xml
<?xml version="1.0" encoding="utf-8"?> <linearlayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical" > <listview android:id="@+id/srlistview" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_weight="0.24" /> </linearlayout> can identify why buttons , listview aren't clickable?
