有没有一种方法总是在一个图形页面显示的缩放控件？我已经使用加缩放控件

Is there a way to always show the zoom controls on a MapView? I have added the zoom controls using

map=(MapView)findViewById(R.id.map);
map.setBuiltInZoomControls(true);

但缩放控件淡入和淡出。我希望他们始终可见。

but the zoom controls fade in and out. I want them to always be visible.

推荐答案

通过把自己的ZoomControls在我的布局XML解决这样的：

Solved this by putting my own ZoomControls in my layout xml:

<ZoomControls android:id="@+id/zoomcontrols"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />

然后设置onClickListeners的再处理变焦：

and then setting up onClickListeners for then to handle the zoom:

	zoomControls = (ZoomControls) findViewById(R.id.zoomcontrols);
	zoomControls.setOnZoomInClickListener(new View.OnClickListener() {
		@Override
		public void onClick(View v) {
			mapController.zoomIn();
		}
	});
	zoomControls.setOnZoomOutClickListener(new View.OnClickListener() {
		@Override
		public void onClick(View v) {
			mapController.zoomOut();
		}
	});
