[英]Relative Layout problem
I implemented a system to have imagebuttons equal to the number of drawables (restaurant logos) so I filter the images starting with prefix "rest". 我实现了一个系统,使其图像按钮的数量等于可绘制对象(餐厅徽标)的数量,因此我过滤了以前缀“ rest”开头的图像。 Its ok up to here.
到这里还可以。 Then I create a GridWiev and put the buttons to it and the root layout is a RelativeLayout.
然后,我创建一个GridWiev并将按钮放到其中,其根布局为RelativeLayout。 However it does not show any imagebuttons after compilation.
但是,编译后它不显示任何图像按钮。 There is my code and xml.
有我的代码和xml。 Thanks for any help.
谢谢你的帮助。

if(rl==null)

if(gv==null)

}
}
Here is the XML 这是XML
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/relativeLayoutRest"
android:layout_width="fill_parent" android:layout_height="fill_parent">
<Button android:layout_alignParentLeft="true"
android:layout_width="50px" android:id="@+id/adbutton"
android:layout_height="fill_parent" android:text="R\nE\nK\nL\nA\nM\nL\nA\nR"
android:textStyle="bold"></Button>
<ScrollView android:id="@+id/scrollViewRest" android:layout_width="wrap_content" android:layout_height="wrap_content">
<LinearLayout android:id="@+id/linearLayoutRest" android:paddingLeft="50px" android:layout_height="fill_parent" android:layout_width="fill_parent"></LinearLayout>
</ScrollView>
</RelativeLayout>
write this line 写这行
rl = (RelativeLayout) findViewById(R.id.relativeLayoutRest); rl =(RelativeLayout)findViewById(R.id.relativeLayoutRest);
after this line setContentView(R.layout.restlist); 在此行之后setContentView(R.layout.restlist);
