如何使一个相对布局复制自身内部线性布局在按钮单击 [英] How to make a Relative Layout Duplicate Itself Inside a Linear Layout On Button Click

问题描述

我有一个警报对话建立一个RelativeLayout的内部。一小部分是内部RelativeLayout的一个ListView。我的xml文件如下：

I have an alert dialogue set up inside a RelativeLayout. A small section is a ListView with a RelativeLayout inside. My xml file is as follows:

<ScrollView xmlns:android="http://schemas.android.com/apk/res/android">
<RelativeLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent" 
    android:padding="10dp">

 ...

<ListView
    android:layout_width="match_parent"
    android:layout_height="match_parent" 
    android:layout_below="@id/bar_main"
    android:id="@+id/dialoguelistview"
    android:padding="10dp">
<RelativeLayout>    
    <EditText
        android:id="@+id/Item"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_marginTop="5dp"          
        android:hint="@string/Item" 
        />

    <EditText
        android:id="@+id/Quantity"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginTop="15dp"
        android:layout_alignParentLeft="true"
        android:hint="@string/Quantity" 
        android:layout_below="@id/Item"/>

    <EditText
        android:id="@+id/Cost"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginTop="15dp"
        android:layout_toRightOf="@id/Quantity"
        android:hint="@string/Cost" 
        android:layout_below="@id/Item"/>

    <Button
        android:id="@+id/Button01"
        android:layout_width="30dip" 
        android:layout_height="30dip" 
        android:layout_alignParentRight="true"
        android:layout_marginTop="20dp"
        android:layout_marginRight="10dp"
        android:layout_below="@id/Item"
        android:background="@drawable/round_button"
        android:text="@string/another_item"
        android:textColor="#fff" 
        android:onClick = "addAnotherItem"></Button>

 </RelativeLayout>
 </ListView>

...

</RelativeLayout>
</ScrollView>

在单击该按钮，我需要内部相对布局重复自己的列表视图中。我怎样才能做到这一点？在此先感谢！

When the button is clicked, I need the inner relative layout to duplicate itself inside the list view. How can I do this? Thanks in advance!

推荐答案

创建一个单独的布局xml文件中的 RealtiveLayout 要膨胀。

Create a separate layout xml file for RealtiveLayout that you want to inflate.

示例

父页面的XML是：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
tools:context="em.example.InfoActivity">

<LinearLayout 
    android:id="@+id/infolayout"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:padding="15dp"
    android:layout_marginTop="50dp">
  </LinearLayout>
</RelativeLayout>

儿童页

<RelativeLayoutxmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:background="#55934d"
android:padding="5dp"> 

<TextView 
    android:id="@+id/TextAddress"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:text="TEXT ADDRESS:"
    android:textSize="10sp"
    android:textColor="#fff"
    />

</RelativeLayout>

这是你的activity.java code

public void addChildLayout(){
    //Inflater service
    LayoutInflater layoutInfralte=(LayoutInflater)getApplicationContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    //parent layout xml refrence
    LinearLayout linearLayout=(LinearLayout)findViewById(R.id.infolayout);
    //Child layout xml refrence
    View view=layoutInfralte.inflate(R.layout.infoitem, null);
    //add child to parent
    linearLayout.addView(view);
    }

使用上面的图案可以动态地添加新的意见。

Using the above pattern you can dynamically add new views.
