android谷歌地图检测双击[关闭]

Question

我想在谷歌地图上检测双击并添加标记，我设置了setOnMapClickListener，并设置了一个点击时间，但是当我点击两次时，setOnMapClickListener 只被调用一次

你必须使用GestureDetector接口。

import android.view.GestureDetector;
import android.view.MotionEvent;

public class GestureDoubleTap extends GestureDetector.SimpleOnGestureListener
{
    @Override
    public boolean onDoubleTap(MotionEvent event)
    {
        Toast.makeText(YourActivity.this, "Double Tap", Toast.LENGTH_SHORT).show();
        return true;
    }
}

GestureDoubleTap gestureDoubleTap = new GestureDoubleTap();
final GestureDetector gestureDetector = new GestureDetector(YourActivity.this, gestureDoubleTap);

yourContent.setOnTouchListener(new View.OnTouchListener()
{
    @Override
    public boolean onTouch(View view, MotionEvent event)
    {
        return gestureDetector.onTouchEvent(event);
    }
});
