我正在编写一个应用程序,需要显示地址,以便我以后可以使用它.我从LocationManager获取位置,并希望在按下时显示显示地址的Toast.我的问题是,当按下按钮时,没有任何反应.(甚至没有在LogCat中)

这是代码:

Button getTaxi = (Button) findViewById(R.id.GetTaxi);
getTaxi.setOnClickListener(new View.OnClickListener() {

    public void getAddress() {
        Geocoder geocoder = new Geocoder(getBaseContext(), Locale.getDefault());
        String result = null;
        try {
            List<Address> list = geocoder.getFromLocation(location.getLatitude(), location.getLongitude(), 1);
            if (list != null && list.size() > 0) {
                Address address = list.get(0);
                // sending back first address line and locality
                result = address.getAddressLine(0) + ", " + address.getLocality();
            }
        } catch (IOException e) {
            String exception = String.format("IOException!!");
            Toast.makeText(getApplicationContext(), exception, Toast.LENGTH_LONG);
        } finally {
            if (result != …

我尝试使用Google maps API开发Android地图应用程序.

使用Google API在多个emulatet Android设备(2.1; 2.3.3; 4.0.3)上进行测试.

问题是logcat向我抛出:
