標題[問題] 地址反查的程式異常
時間Thu Aug 2 21:24:43 2012
請問各位先進,小弟的程式碼如下
小弟想做一個輸入地址可返回經緯度然後顯示在Google Map的小程式,
但是當我將地址輸入後按下確認卻一直發生程式異常,
看了執行的Log卻沒看到明顯的錯誤訊息,所以請大家幫忙來找茬！
先謝謝大家.
public class MyLocation extends MapActivity {
private MapView mapView;
private Geocoder geoCoder;
private GeoPoint geoPoint;
private EditText addressEdit;
private Button resetBut, submitBut;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_my_location);
addressEdit = (EditText) findViewById(R.id.addressEdit);
mapView = (MapView) findViewById(R.id.mapView);
mapView.getController();
mapView.setSatellite(true);
mapView.setStreetView(true);
submitBut = (Button) findViewById(R.id.submitBut);
submitBut.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
if (addressEdit.getText().toString() != "") {
refreshMapViewByGeoPoint(getGeoByAddress(
addressEdit.getText().toString()), mapView, 17, true);
}
}
});
resetBut = (Button) findViewById(R.id.resetBut);
resetBut.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
addressEdit.setText("");
}
});

mc.setZoom(zoom);
if (bIfSatelite) {
mapview.setSatellite(true);

} else {
Log.d("TAG", "Address GeoPoint NOT found.");
}
}
} catch (IOException e) {
// TODO Auto-generated catch block
