Android的 - 动态添加视图到视图 [英] Android - Dynamically Add Views into View

问题描述

我有一个观点的布局 -

I have a layout for a view -

<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:padding="0px"
    android:orientation="vertical">

    <TextView
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:id="@+id/items_header"
        style="@style/Home.ListHeader" />

    <TextView 
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:id="@+id/items_none"
        android:visibility="gone"
        style="@style/TextBlock"
        android:paddingLeft="6px" />

    <ListView 
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:id="@+id/items_list" />


</LinearLayout>

我想要做的，是我的主要活动有这样的布局

What I want to do, is in my main activity with a layout like this

<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:padding="0px"
    android:id="@+id/item_wrapper">
</LinearLayout>

我要循环通过我的数据模型，并注入由第一布局到主布局的多个视图。我知道我可以通过内部的code全面建设的控制做到这一点，但我不知道是否有一种方法可以动态生成的观点，这样我就可以继续使用布局，而不是把一切都在code。

I want to loop through my data model and inject multiple views consisting of the first layout into the main layout. I know I can do this by building the controls completely within the code, but I was wondering if there was a way to dynamically build the views so that I can continue using a layout instead of putting everything in code.

推荐答案

使用的<一个href="http://developer.android.com/reference/android/view/LayoutInflater.html"><$c$c>LayoutInflator根据您的布局模板创建一个视图，然后将其注入在你需要它的观点。

Use the LayoutInflator to create a view based on your layout template, and then inject it into the view where you need it.

LayoutInflater vi = (LayoutInflater) getApplicationContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View v = vi.inflate(R.layout.your_layout, null);

// fill in any details dynamically here
TextView textView = (TextView) v.findViewById(R.id.a_text_view);
textView.setText("your text");

// insert into main view
ViewGroup insertPoint = (ViewGroup) findViewById(R.id.insert_point);
insertPoint.addView(v, 0, new ViewGroup.LayoutParams(ViewGroup.LayoutParams.FILL_PARENT, ViewGroup.LayoutParams.FILL_PARENT));

您可能需要调整的指数要插入的视图。

You may have to adjust the index where you want to insert the view.
