第四步:PathTestActivity.java以及用到的布局文件main.xml代码如下:
PathTestActivity.java(基本没修改代码)代码如下:
[java] view plain copy
-
package com.tutor.path;
-
import android.app.Activity;
-
import android.os.Bundle;
-
public class PathTestActivity extends Activity {
-
@Override
-
public void onCreate(Bundle savedInstanceState) {
-
super.onCreate(savedInstanceState);
-
setContentView(R.layout.main);
-
}
-
}
main.xml代码如下:
[java] view plain copy
- <?xml version="1.0" encoding="utf-8"?>
-
<LinearLayout xmlns:android=“http://schemas.android.com/apk/res/android”
-
xmlns:tutor=“http://schemas.android.com/apk/res/com.tutor.path”
-
android:layout_width=“fill_parent”
-
android:layout_height=“fill_parent”
-
android:orientation=“vertical” >
-
<com.tutor.path.PathMenuView
-
android:id="@+id/text"
-
android:layout_width=“fill_parent”
-
android:layout_height=“fill_parent”
-
tutor:position=“right_bottom”
-
/>
