添加视图到的LinearLayout在指定位置 [英] Adding a view to a LinearLayout at a specified position

问题描述

我有一个LinearLayout中下面的main.xml文件

I have the following main.xml file with a LinearLayout

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:weightSum="1" android:id="@+id/llid">
    <TextView android:text="Client profile"
    android:id="@+id/ProfileName"
    android:layout_width="fill_parent"
    android:textStyle="bold"
    android:layout_height="wrap_content"
    android:gravity="center_horizontal">
    </TextView>    
    <TextView android:text="Specs"
    android:id="@+id/Specs"
    android:layout_width="fill_parent"
    android:textStyle="bold"
    android:layout_height="wrap_content"
    android:gravity="center_horizontal">
    </TextView>
</LinearLayout>

我的图像通过code在运行时添加到LinearLayout中，像这样

I add an image to the LinearLayout via code at runtime like so

            ImageView image = new ImageView(this);
            image.setImageBitmap(bmp);
            LinearLayout ll = (LinearLayout) findViewById(R.id.llid);
            ll.addView(image);  

不过，我想增加2 TextViews之间的ImageView在我的LinearLayout。我似乎无法找到一种方法在Android文档添加一个视图中的另一个视图之前，或之后。我怎样才能做到这一点？

However, I want to add the ImageView between the 2 TextViews in my LinearLayout. I can't seem to find a way in the android docs to add a view before another view, or after. How can I do this?

NB 我称之为

setContentView(R.layout.main);

在我添加的ImageView到的LinearLayout。

Before I add the ImageView to the LinearLayout.

推荐答案

在添加查看到的ViewGroup ，您可以<一href="http://developer.android.com/reference/android/view/ViewGroup.html#addView%28android.view.View,%20int%29">specify索引这台父视图的位置。

When adding a View to a ViewGroup, you can specify an index which sets the position of the view in the parent.

您有两种意见，因此（从零算起）你想添加的第一个位置;只需拨打 ll.addView（图像，1）; 将它放置在二者之间 TextViews

You have two views and so (counting from zero) you would want to add at the 1st position; just call ll.addView(image, 1); to have it placed in between the two TextViews.
