本文介绍了一种在Android应用中动态加载布局的方法。通过在主布局文件中预留位置，并使用Java代码根据需要动态添加子布局视图，实现了灵活的UI展示。文章提供了具体的XML布局文件示例及对应的Java代码片段。

在布局中动态加载View

1.主布局的funddatail.xml

<?xml version="1.0" encoding="UTF-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
 android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@color/white"
    android:scrollbars="vertical" >

    <LinearLayout
           android:id="@+id/fund_manger_layout"
            android:layout_width="match_parent"                android:layout_height="wrap_content"     android:orientation="vertical" > 
</LinearLayout> 
</LinearLayout>

2.动态加载的Item fund_manger_detail.xml

<?xml version="1.0" encoding="UTF-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@color/white"
    android:orientation="vertical" >
    
    <LinearLayout
       
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginTop="10dp"
        android:background="@color/photo_day_bg"
        android:padding="5dp" >

        <TextView
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:gravity="center_vertical"
            android:text="姓名"
            android:textColor="@color/widget_summary"
            android:textSize="@dimen/comment_text_size" />

        <TextView
            android:id="@+id/fund_basedata_manger_tv01"
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:layout_weight="4"
            android:gravity="left"
            android:textColor="@color/black"
            android:textSize="@dimen/comment_text_size" />
    </LinearLayout>

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="@color/white"
        android:orientation="horizontal"
        android:padding="5dp" >

        <TextView
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:gravity="center_vertical"
            android:text="学历"
            android:textColor="@color/widget_summary"
            android:textSize="@dimen/comment_text_size" />

        <LinearLayout
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:layout_weight="4"
            android:orientation="horizontal" >

            <TextView
                android:id="@+id/fund_basedata_manger_tv02"
                android:layout_width="0dp"
                android:layout_height="wrap_content"
                android:layout_weight="1"
                android:gravity="left"
                android:textColor="@color/black"
                android:textSize="@dimen/comment_text_size" />

            <TextView
                android:layout_width="0dp"
                android:layout_height="wrap_content"
                android:layout_weight="1"
                android:gravity="left"
                android:text="任职日期"
                android:textColor="@color/widget_summary"
                android:textSize="@dimen/comment_text_size" />

            <TextView
                android:id="@+id/fund_basedata_manger_tv03"
                android:layout_width="0dp"
                android:layout_height="wrap_content"
                android:layout_weight="1"
                android:gravity="center_vertical"
                android:textColor="@color/black"
                android:textSize="@dimen/comment_text_size" />
        </LinearLayout>
    </LinearLayout>

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="@color/photo_day_bg"
        android:orientation="horizontal"
        android:padding="5dp" >

        <TextView
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:gravity="center_vertical"
            android:text="简介"
            android:textColor="@color/widget_summary"
            android:textSize="@dimen/comment_text_size" />

        <TextView
            android:id="@+id/fund_basedata_manger_tv04"
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:layout_weight="4"
            android:gravity="left"
            android:textColor="@color/black"
            android:textSize="@dimen/comment_text_size" />
    </LinearLayout>

</LinearLayout>

3.在类中动态的加载：

    ViewGroup.LayoutParams  prarms = new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT,
                ViewGroup.LayoutParams.WRAP_CONTENT);
        fund_manger_layout.removeAllViews();
        
        if(baseinfos.size()<0){
            manger_layout_name.setVisibility(View.GONE);
        }
        for(int  i=0;i<baseinfos.size();i++){
            
            View   mangerlayout=View.inflate(activity, R.layout.fund_manger_detail, null);
            fund_basedata_manger_tv01=(TextView) mangerlayout.findViewById(R.id.fund_basedata_manger_tv01);
            fund_basedata_manger_tv02=(TextView) mangerlayout.findViewById(R.id.fund_basedata_manger_tv02);
            fund_basedata_manger_tv03=(TextView) mangerlayout.findViewById(R.id.fund_basedata_manger_tv03);
            fund_basedata_manger_tv04=(TextView) mangerlayout.findViewById(R.id.fund_basedata_manger_tv04);
            
            fund_basedata_manger_tv01.setText(baseinfos.get(i).getManger_name());
            fund_basedata_manger_tv02.setText(baseinfos.get(i).getEducation());
            fund_basedata_manger_tv03.setText(baseinfos.get(i).getTake_date());
            fund_basedata_manger_tv04.setText(baseinfos.get(i).getDetail());
            fund_manger_layout.addView(mangerlayout, prarms);
            
        }
