Question

我想以编程方式将View添加到mainHolder，声明如下：

<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#000000" >

<LinearLayout
    android:id="@+id/mainHolder"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:background="#000000"
    android:orientation="horizontal" />

我希望新视图填满屏幕高度。怎么可能？

Answer 1

试试这个：

LinearLayout mainHolder = (LinearLayout)findViewById(R.id.mainHolder);
//untested adding of view I got it from http://stackoverflow.com/questions/5731487/how-to-add-views-to-linear-layout
mainHolder.addView(View, mainHolder);
//this is tested however
View.setMinimumHeight(mainHolder.getHeight());

Answer 2

设置线性布局属性机器人：layout_width = “match_content” 机器人：layout_height = “match_content”

然后添加以下代码： LinearLayout mainHolder =（LinearLayout）findViewById（R.id.mainHolder）;

    RelativeLayout.LayoutParams layer=new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.MATCH_PARENT, 
            RelativeLayout.LayoutParams.MATCH_PARENT);
    layer.addRule(RelativeLayout.ALIGN_PARENT_TOP);


    mainHolder.addView(layer);

与上述代码相同，您可以以编程方式添加视图
