>要求：需要创建自定义视图(使用xml布局文件),以便在我的应用程序活动中使用相同的视图.在这里,我使用我正在处理的示例代码,

cutomviewxml.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="Large Text"
        android:textAppearance="?android:attr/textAppearanceLarge" />
</LinearLayout>

扩展视图类…代码……

mycustomTextview.java

public class mycustomTextview extends View {
 
    private View mView;
    Context mycontext;
 
    public mycustomTextview(Context context,AttributeSet attrs) {
        super(context,attrs);
        // TODO Auto-generated constructor stub
 
    this.mycontext = context;
 
    LayoutInflater inflater;
    inflater = (LayoutInflater) context
            .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    mView = inflater.inflate(R.layout.cutomviewxml,null);
    }

Activity main.xml文件

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >
 
 
     <com.motorola.mycustomTextview
         android:id="@+id/customtextview"
         android:layout_width="fill_parent"
         android:layout_height="wrap_content"
         android:layout_below="@+id/textView2"
         android:layout_marginLeft="143dp"
         android:layout_marginTop="69dp"
         android:layout_toRightOf="@+id/textView1" />
 
</RelativeLayout>

Activity类sample.java ..

public class sample extends Activity{
 
    private static final String LOG_TAG = "sampleActivity";
 
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        Log.i(LOG_TAG,"OnCreate of sampleActivity");
        setContentView(R.layout.main);
}
}
