我正在尝试在 AlertBox 中填充 XML(Layout)。

这是我要膨胀的 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:orientation="vertical" >

    <TextView
        android:id="@+id/textView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/update_information" />

    <CheckBox
        android:id="@+id/chbDisplay"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Don't Show Again"
        android:checked="true" />

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content" >

        <Button
            android:id="@+id/btnCancel"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="Cancel" />

        <Button
            android:id="@+id/btnOk"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="Ok" />



    </LinearLayout>

</LinearLayout>

这是我用来膨胀 XML 的代码...

private void display_Update_Info() {
        // TODO Auto-generated method stub

        LayoutInflater in = new LayoutInflater(this) {

            @Override
            public LayoutInflater cloneInContext(Context newContext) {
                // TODO Auto-generated method stub
                return null;
            }//This code is auto generated. I have no idea what is this...
        };

        final View update = in.inflate(R.layout.updateinformation, null);


        AlertDialog.Builder updateInfo = new Builder(this);
        updateInfo.setView(update);
        updateInfo.show();

    }

这是 Logcat 跟踪...

另外，如果有人可以告诉我，自动生成的代码有什么用...

@Override
public LayoutInflater cloneInContext(Context newContext) {
// TODO Auto-generated method stub
return null;
}

当我尝试运行应用程序时，我被强制关闭...

而不是这个

   LayoutInflater in = new LayoutInflater(this) {

        @Override
        public LayoutInflater cloneInContext(Context newContext) {
            // TODO Auto-generated method stub
            return null;
        }//This code is auto generated. I have no idea what is this...
    };

用这个

   LayoutInflater in = getLayoutInflater();

对于第二部分，请参阅 api 文档http://developer.android.com/reference/android/view/LayoutInflater.html#cloneInContext(android.content.Context)。
