Question

我正在尝试创建一个app，其中父布局是一个可滚动的视图，我使用以下代码动态地向该父布局添加一个视图：

    LinearLayout ll = (LinearLayout) findViewById(R.id.parent);

    for(int i=0;i<5;i++){
        LayoutInflater inflater = (LayoutInflater) getSystemService( Context.LAYOUT_INFLATER_SERVICE );
        View format = inflater.inflate(R.layout.student_present_absent,null);
        ll.addView(format);
    }

以下是我要插入视图的视图：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
 android:layout_width="match_parent" android:layout_height="match_parent"
 android:orientation="vertical"
 android:background="@drawable/backgroundf"

            android:layout_weight="1.1">
            <LinearLayout

问题是代码插入了student_present_absent.xml的整个页面所以我得到了student_present_absent.xml的全屏5次，我只想让70DP的布局重复5次。

请帮忙。

Answer 1

这听起来像是具有多种布局的Listview / Recyclerview的用例。

使用谷歌我发现以下链接...我没有测试它，但它看起来很擅长：

Answer 2

您可以添加5个视图静态，如下所示。

LayoutInflater inflater = (LayoutInflater) getSystemService( Context.LAYOUT_INFLATER_SERVICE );

 View format = inflater.inflate(R.layout.student_present_absent,null);
 View format1 = inflater.inflate(R.layout.student_present_absent,null);
 View format2 = inflater.inflate(R.layout.student_present_absent,null);
 View format3 = inflater.inflate(R.layout.student_present_absent,null);
 View format4 = inflater.inflate(R.layout.student_present_absent,null);
  ll.addView(format);
  ll.addView(format1);
  ll.addView(format2);
  ll.addView(format3);
  ll.addView(format4);
