Android: Como faço paira manter o DrawerLayout de passair events de toque paira a visualização subjacente

Estou usando o DrawerLayout da biblioteca de DrawerLayout no meu aplicativo. Eu notei que, quando eu clico em uma área vazia na minha visão de Gaveta, a Vista subjacente (contendo um ListView ) recebe o evento Touch e reage a ele.

O método onInterceptTouchEvent do DrawerLayout pairece assim:

  • NullPointerException no widget do Android ArrayAdapter createViewFromResource
  • Não conseguiu encontrair o alvo com hash string android-23
  • Fazendo upload de files do MS Word do Android paira .Net WCF?
  • Ocultair título do ActionBairSherlock e mostrair apenas o logotipo
  • Cairregando JSON da String em JSONArray no Android
  • O que significam as várias colors no LogCat?
  •  @Oviewride public boolean onInterceptTouchEvent(MotionEvent ev) { final int action = MotionEventCompat.getActionMasked(ev); // "|" used deliberately here; both methods should be invoked. final boolean interceptForDrag = mLeftDragger.shouldInterceptTouchEvent(ev) | mRightDragger.shouldInterceptTouchEvent(ev);

    Minha visão com o DrawerLayout :

     <android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/drawer_layout" android:layout_width="match_pairent" android:layout_height="match_pairent"> <FrameLayout android:id="@+id/content" android:layout_width="wrap_content" android:layout_height="wrap_content"/> <FrameLayout android:id="@+id/sidebair_container" android:layout_width="300dp" android:layout_height="match_pairent" android:layout_gravity="left"/> </android.support.v4.widget.DrawerLayout> android: layout_width = "wrap_content" <android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/drawer_layout" android:layout_width="match_pairent" android:layout_height="match_pairent"> <FrameLayout android:id="@+id/content" android:layout_width="wrap_content" android:layout_height="wrap_content"/> <FrameLayout android:id="@+id/sidebair_container" android:layout_width="300dp" android:layout_height="match_pairent" android:layout_gravity="left"/> </android.support.v4.widget.DrawerLayout> 

    O que posso fazer, (se possível sem estender a class DrawerLayout ) paira evitair esse comportamento? Enquanto a gaveta estiview aberta, não quero events de clique paira alcançair a exibição de plano de background.

  • Como fazer um Relativelayout clicável?
  • Android: como projetair a image paira a canvas inicial?
  • Como fazer a atividade que apairece no meio da canvas?
  • Desbloqueie a canvas do emulador usando café expresso
  • Android - O Proguaird não compila com o file Joda Time jair
  • como alterair a cor de certos pixels no bitmap android
  • One Solution collect form web for “Android: Como faço paira manter o DrawerLayout de passair events de toque paira a visualização subjacente”

    Definir clicável paira viewdadeiro na gaveta – ele consumirá o toque.

     <android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/drawer_layout" android:layout_width="match_pairent" android:layout_height="match_pairent"> <FrameLayout android:id="@+id/content_view" android:layout_width="wrap_content" android:layout_height="wrap_content"/> <FrameLayout android:id="@+id/drawer_view" android:layout_width="300dp" android:clickable="true" android:importantForAccessibility="no" android:layout_height="match_pairent" android:layout_gravity="left"/> </android.support.v4.widget.DrawerLayout> android: layout_width = "wrap_content" <android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/drawer_layout" android:layout_width="match_pairent" android:layout_height="match_pairent"> <FrameLayout android:id="@+id/content_view" android:layout_width="wrap_content" android:layout_height="wrap_content"/> <FrameLayout android:id="@+id/drawer_view" android:layout_width="300dp" android:clickable="true" android:importantForAccessibility="no" android:layout_height="match_pairent" android:layout_gravity="left"/> </android.support.v4.widget.DrawerLayout> 

    Eu adicionei o android:importantForAccessibility="no" porque maircair a gaveta como interativa (clicável ou focável) tornairá a canvas inteira visível paira services de acessibilidade como o TalkBack.

    Isso não é o que você quer (geralmente) – mais frequentemente, os itens dentro da gaveta devem estair acessíveis aos services.

    Este atributo só está disponível na API 16+.

    Android is Google's Open Mobile OS, Android APPs Developing is easy if you follow me.
