我正在开发一个Android应用程序。这与全球相同。我想设置点击地球上提到的点(城市)。我也有地球上提到的要点的数据库(纬度,长度和其他数据)。我想要的功能是,当我点击地球时,我想搜索纽约市,它得到了纽约市的长途,并从数据库中提供了所有细节。问题是我设置了数据库,但是当我点击地球时它不会给我详细信息,所以我想增加点击区域。

如果是VIEW对象,这可能会有所帮助:
public static void increaseClickArea(View parent, View child) {
// increase the click area with delegateArea, can be used in + create
// icon
final View chicld = child;
parent.post(new Runnable() {
public void run() {
// Post in the parents message queue to make sure the
// parent
// lays out its children before we call getHitRect()
Rect delegateArea = new Rect();
View delegate = chicld;
delegate.getHitRect(delegateArea);
delegateArea.top -= 600;
delegateArea.bottom += 600;
delegateArea.left -= 600;
delegateArea.right += 600;
TouchDelegate expandedArea = new TouchDelegate(delegateArea,
delegate);
// give the delegate to an ancestor of the view we're
// delegating the
// area to
if (View.class.isInstance(delegate.getParent())) {
((View) delegate.getParent())
.setTouchDelegate(expandedArea);
}
};
});
}
