Hello Guys我在Android应用程序中遇到问题。 我制作了一个Android应用程序，然后在LG optimus 2x上用ICS安卓版测试了它 但是当我在SONY xperia C上测试它时，它给了我一些问题
第一个也是最重要的问题是我在我的应用程序中创建了一个菜单，它通过在我的Lg optimus 2x上按下选项硬件键打开，但是在带有JB安卓操作系统的sony Xperia C中，硬件键已经准备就绪了到其他一些功能，并没有打开我的选项菜单
现在我要做的是我想制作一个屏幕上的选项按钮，我将用它在菜单中调用。
我已经制作了一个按钮，但我不知道如何将我的按钮链接到我的应用程序菜单中调用
下面的是我的layout.xml文件中的代码
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical"
>
<TextView
android:id="@+id/colortxt"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Result will be displayed here.."
android:textColor="#000000"
android:textSize="12sp"
/>
</LinearLayout>
<Button
android:id="@+id/Button"
android:textColorLink="#3334"
android:shadowColor="#4445"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:onClick="Buttonbtn1"
android:text="Options"
/>
<org.opencv.android.JavaCameraView
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:id="@+id/color_blob_detection_activity_surface_view" />
这是我的.java文件中的代码

并且第二个问题是我的应用程序调用了相机功能，但是当它在SONY xperia C中打开相机时它没有使用相机的全屏但是只使用了它的一小部分，因为这个应用程序使用了全部屏幕相机，当我在旧的Lg optimus 2x上运行它
伙计们，请帮助我知道在哪里和什么代码，以便我 达到预期的效果。
