我是Android世界的新手......如果有人纠正我,那将是一个很大的帮助......我在下面的代码中做错了什么......
- 要求:需要创建一个自定义视图(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);
}
活动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>
活动类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);
}
}
