デフォルトアクティビティからアクティビティを呼び出そうとしていますが、コールアクティビティをトリガーすると、アプリケーションがクラッシュしてこの07-06 11:54:59.291: E/MapActivity(366): Couldn't get connection factory clientメッセージで閉じられました。アクティビティを呼び出すための現在のコードは次のとおりです
public class GMapsActivity extends MapActivity {
EditText password;
Button login;
MapView mapView;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
initcontrols();
}
public void initcontrols()
{
password=(EditText)findViewById(R.id.pass);
login=(Button)findViewById(R.id.login);
mapView=(MapView)findViewById(R.id.map_view);
login.setOnClickListener(new Button.OnClickListener(){
public void onClick(View v)
{
Intent myIntent = null;
if(password.getText().toString().equals("admin")) {
System.out.println("Entering");
mapView.setVisibility(View.VISIBLE);
login.setVisibility(View.INVISIBLE);
password.setVisibility(View.INVISIBLE);
myIntent = new Intent(v.getContext(), GMapsActivity1.class);
} else {
}
startActivity(myIntent);
}
});
}
@Override
protected boolean isRouteDisplayed() {
// TODO Auto-generated method stub
return false;
}
}
誰でも私がこれを行うのを手伝ってください
更新 は私の 2 番目のアクティビティ コードです。変更が必要かどうかを確認してください
public class GMapsActivity1 extends MapActivity {
private MapView mapView;

String result = null;
InputStream is = null;
StringBuilder sb=null;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
mapView = (MapView) findViewById(R.id.map_view);
mapView.setBuiltInZoomControls(true);
ArrayList<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
//http post
try{
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("http://sml.com.pk/a/map.php");
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
HttpResponse response = httpclient.execute(httppost);
HttpEntity entity = response.getEntity();
is = entity.getContent();
}catch(Exception e){
Log.e("log_tag", "Error in http connection"+e.toString());
}
//convert response to string
try{
