膨胀视图

我试图膨胀一个视图，充当我的glSurfaceView的加载屏幕，同时在运行期间交换纹理（我知道如何在我的onCreate中完成）。它只是一个RelativeLayout，中间有一个进度条，当它完成交换后，它会消失，但它不会正确膨胀。膨胀视图

inflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
    loading = inflater.inflate(R.layout.loading,null); 
RelativeLayout loadingScreen = (RelativeLayout) findViewById(R.id.loadingScreen);

其中loadingScreen是相对布局的ID。

XML：

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:id="@+id/loadingScreen" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" 
    android:background="#FFFFFF" 
    android:visibility="visible" > 

    <ProgressBar 
     android:id="@+id/progressBar1" 
     style="?android:attr/progressBarStyleLarge" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:layout_centerInParent="true" > 
    </ProgressBar> 

    <EditText 
     android:id="@+id/editText android:layout_height=" 
     android:layout_width="wrap_content" 
     wrap_content="" > 
    </EditText> 

</RelativeLayout>

对于测试，我添加上面的以下附加代码一个EditText来测试它：

EditText tester = (EditText) findViewById(R.id.editText); //Now we have an object 
    tester.setText("dfdfds");

和错误日志：

尝试loading.findViewById（...）而不只是findViewById（...）

这似乎工作，它不再崩溃，但我不能看到它。任何想法，我怎么能使它膨胀在当前的观点？ – jfisk

一旦视图膨胀到对象“加载”中，就会像处理其他布局对象一样对待它，并使用addView将其附加到现有布局。充气只是将xml中的复杂布局加载到内存中的一种快速而简单的方法，而不是通过代码手动构建。如果你想替换你已经加载的所有布局对象，我会简单地得到顶层的父布局，删除所有的子元素，并追加“加载” – atraudes

我不需要删除以前，认为它几乎是一个飞溅屏幕。我在我的main.xml文件中设置了我的glSurfaceView，我将如何在这个组合中使用addView？ – jfisk

我也有这些类型的错误。我发现错误是因为我的文本编辑器名称与我的文本编辑器ID不匹配。

当你inflatet你发现孩子的看法是这样

inflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
    loading = inflater.inflate(R.layout.loading,null); 
    RelativeLayout loadingScreen = (RelativeLayout) loading.findViewById(R.id.loadingScreen);
