我能在模拟器上跑出来google map但是加了一下代码之后按按钮就直接崩溃了。求解答！！
> searchBt=(Button)findViewById(R.id.btnSearch);
searchBt.setOnClickListener(new OnClickListener(){
public void onClick(View v) {
EditText etLongitude = (EditText) findViewById(R.id.etLongitude);
EditText etLatitude = (EditText) findViewById(R.id.etLatitude);
if (etLongitude.getText().toString().equals("") ||
etLatitude.getText().toString().equals(""))
{ // 判断是否输入空值
showDialog(" 不能为空");
}
else
{
longitude = Double.parseDouble(etLongitude.getText().toString());
latitude = Double.parseDouble(etLatitude.getText().toString());
refreshMapView(); // 调用方法更新Map
}
}
});
}
private void refreshMapView() {
// TODO Auto-generated method stub
GeoPoint p = new GeoPoint((int)(longitude* 1E6), (int)(latitude* 1E6));
mMapView01.displayZoomControls(true);
mMapController01.animateTo(p);
mMapController01.setZoom(intZoomLevel);
}
protected boolean isRouteDisplayed()
{
return false;
}
private void showDialog(String mess){
new AlertDialog.Builder(MainActivity.this).setTitle("Message")
.setMessage(mess)
.setNegativeButton("经度纬度请补全", new DialogInterface.OnClickListener()
{
public void onClick(DialogInterface dialog, int which)
{
}
})
.show();
