我在MapActivity.java中创建一个OSMdroid mapview,我想添加按钮&弹出窗口 - 我只知道这是如何在.xml中完成的,但由于这个MapView没有使用任何.xml,我很困惑如何在我的java代码中放置(图像)按钮。
@Override
public void onCreate(final Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Setup base map
final RelativeLayout rl = new RelativeLayout(this);
CloudmadeUtil.retrieveCloudmadeKey(getApplicationContext());
final MapView osmv = new MapView(this, 256);
myMapController = osmv.getController();
rl.addView(osmv, new RelativeLayout.LayoutParams(LayoutParams.FILL_PARENT,
LayoutParams.FILL_PARENT));
osmv.setBuiltInZoomControls(true);
osmv.setMultiTouchControls(true);
myLocationoverlay = new MyLocationOverlay(this, osmv);
//*snip* setup of map, mapcontrollers, tiles etc...
osmv.getOverlays().add(tilesOverlay);
osmv.getOverlays().add(myLocationoverlay);
this.setContentView(rl);
}
编辑: 我在谈论像
这样的按钮<ImageButton
android:id="@+id/map_goto_location"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/goto_location"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"
android:id="@+id/goto_location" />
答案 0 :(得分:4)
感谢MH的提示,我发现如何以编程方式将ImageButton添加到我的代码中,如下所示:
ImageButton goto_location = new ImageButton(this);
goto_location.setOnClickListener(new OnClickListener()
{
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
showMylocation();
}
});
RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(40, 40);
params.rightMargin = 10;
params.topMargin = 10;
rl.addView(goto_location, params);
如果有人可以在一些关于自定义按钮的好教程/示例上提示我,并且以编程方式添加UI元素,我将非常高兴。
