>我有一个创建视图子对象的活动类
public class DaDActivity extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(new DragSurface(this));
}
}
这是我的拖拽表面.java
public class DragSurface extends View{
public DragSurface(Context context) {
super(context);
setFocusable(true);
}
}
我也有 dragsurface.xml 文件,但我不知道如何在我的 DragSurface 中使用这个 xml 文件.java.我的意思是我希望 DragSurface.java 在 dragsurface 中使用背景、按钮或类似的东西.xml但我无法.java链接到.xml
感谢您的帮助..
LayoutInflater inflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View view = inflater.inflate(R.layout.yourlayout,null);
尝试上面的行来膨胀您的 XML 文件。尝试以下代码
:::public class DaDActivity extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(new DragSurface(this).createView());
}
}
这是我的拖拽表面.java
public class DragSurface extends View{
public DragSurface(Context context) {
super(context);
setFocusable(true);
}
public View createView(){
LayoutInflater inflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View view = inflater.inflate(R.layout.yourlayout,null);
return view;
}
}
