Question

我有一个相对布局我想动态创建布局，XMl中的布局看起来像

<RelativeLayout
        android:id="@+id/relativeLayout1"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_margin="5sp"
        android:background="@drawable/step_background"
        android:orientation="vertical" >

我这样做 -

RelativeLayout.LayoutParams lprams = new RelativeLayout.LayoutParams(
                RelativeLayout.LayoutParams.MATCH_PARENT,
                RelativeLayout.LayoutParams.MATCH_PARENT);
        lprams.setMargins(5,5,5,5);

但是如何添加背景我在片段而非活动中这样做

Answer 1

尝试如下......

    RelativeLayout layout = new RelativeLayout(this);

    RelativeLayout.LayoutParams lprams = new RelativeLayout.LayoutParams(
            RelativeLayout.LayoutParams.MATCH_PARENT,
            RelativeLayout.LayoutParams.MATCH_PARENT);
    lprams.setMargins(5,5,5,5);

    layout.setLayoutParams(lprams);

    layout.setBackgroundResource(R.drawable.step_background);

Answer 2

试试这个： -

RelativeLayout mRelativeLayoutPopup = new RelativeLayout(context);
RelativeLayout.LayoutParams layoutParams = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.MATCH_PARENT, RelativeLayout.LayoutParams.MATCH_PARENT);
layoutParams.setMargins(5,5,5,5);
mRelativeLayoutPopup.setLayoutParams(layoutParams);     
mRelativeLayoutPopup.setBackgroundResource(drawable_background);

Answer 3

您可以使用setBackground。

Drawable bg_image= getResources().getDrawable(R.drawable.image); 
myLayout.setBackground(bg_image);

希望它有所帮助。
