从SplashScreen活动转移到AnotherActivity. 问题是我在屏幕加载BlackScreen之前SplashScreen消失了。MainActivity
有没有人有什么建议？
这是我的代码：
public class Splash extends Activity{
public List<SaxMessage> torimsg = new ArrayList<SaxMessage>();
static final int DIALOG_ERROR_CONNECTION = 1;
static final int DIALOG_ERROR_CONNECTION2 = 2;
static final int DIALOG_ERROR_CONNECTION3 = 3;
Boolean connected;
String dialogMessage;
Context context;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
SplashHandler mHandler = new SplashHandler();
setContentView(R.layout.splash);
context=getApplicationContext();
connected=isOnline(getApplicationContext());
Log.d("connection","connection:"+connected);
// Create a Message object
Message msg = new Message();
//Assign a unique code to the message.
//Later, this code will be used to identify the message in Handler class.
msg.what = 0;
// Send the message with a delay of 3 seconds(3000 = 3 sec).
mHandler.sendMessageDelayed(msg, 1000);
} //onCreate
private Boolean isOnline(Context conn) {
ConnectivityManager cm = (ConnectivityManager)conn. getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo networkinfo = cm.getActiveNetworkInfo();
if (networkinfo != null && networkinfo.isAvailable()
&& networkinfo.isConnected()) {
return true;
}
return false;
}
@Override
protected Dialog onCreateDialog(int id) {
Dialog dialog = null;
switch (id) {
case DIALOG_ERROR_CONNECTION:
AlertDialog.Builder errorDialog = new AlertDialog.Builder(this);
errorDialog.setTitle("Error");
errorDialog.setMessage(dialogMessage);
errorDialog.setNeutralButton("Retry",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
dialog.dismiss();
torimsg.clear();
new DownloadLocalXmlTask().execute();
}
});
AlertDialog errorAlert = errorDialog.create();
return errorAlert;
case DIALOG_ERROR_CONNECTION2:
AlertDialog.Builder errorDialog1 = new AlertDialog.Builder(this);
errorDialog1.setTitle("Error");
errorDialog1.setMessage("No internet connection.");
errorDialog1.setNeutralButton("OK",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
dialog.dismiss();
Splash.this.finish();
}
});
AlertDialog errorAlert1 = errorDialog1.create();
return errorAlert1;
case DIALOG_ERROR_CONNECTION3:
AlertDialog.Builder errorDialog2 = new AlertDialog.Builder(this);
errorDialog2.setTitle("Error");
errorDialog2.setMessage(dialogMessage);
errorDialog2.setNeutralButton("Ok",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
dialog.dismiss();
Splash.this.finish();
}
});
AlertDialog errorAlert2 = errorDialog2.create();
return errorAlert2;
default:
break;
}
return dialog;
}
private class DownloadXmlTask extends AsyncTask<String, Void, List<SaxMessage>>{
@Override
protected List<SaxMessage> doInBackground(String... urls) {
try{
SAXParserFactory saxParserFactory= SAXParserFactory.newInstance();
SAXParser saxParser = saxParserFactory.newSAXParser();
XMLReader xr = saxParser.getXMLReader();
URL sourceUrl = new URL ("http://toucheradio.com/toneradio/android/toriLite/toriplaylist.xml");
RssHandler handler = new RssHandler();
xr.setContentHandler(handler);
xr.parse(new InputSource(sourceUrl.openStream()));
torimsg= handler.getMessages();
torimsg.remove(0);
return torimsg;
}
catch(UnknownHostException e)
{
showMyDialog(e.getMessage());
return null;
}
catch(SAXParseException se)
{
showMyDialog(se.getMessage());
return null;
}
catch (Exception e) {
showMyDialog(e.getMessage());
return null;
}
}
@Override
protected void onPostExecute(List<SaxMessage> result) {
if(result==null)
{
showDialog(DIALOG_ERROR_CONNECTION);
}
else
{
Intent intent= new Intent(Splash.this,TORiLTActivity.class);
Bundle b=new Bundle();
b.putParcelableArrayList("torimsg", (ArrayList<? extends Parcelable>) torimsg);
intent.putExtras(b);
startActivity(intent);
// finish the current activity
Splash.this.finish();
}
}
}
private void showMyDialog(String b) {
Splash.this.dialogMessage=b;
}
private class SplashHandler extends Handler {
//This method is used to handle received messages
public void handleMessage(Message msg)
{
// switch to identify the message by its code
switch (msg.what)
{
default:
case 0:
super.handleMessage(msg);
if(connected==false)
{
showDialog(DIALOG_ERROR_CONNECTION2);
}
else
{
new DownloadXmlTask().execute();
}
}
}
}
}
更新：
public void onCreate(Bundle savedInstanceState) {
Log.i("HS1", "onCreate");
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Bundle recdData = getIntent().getExtras();
messages = recdData.getParcelableArrayList("torimsg");
//new getHtmlDataAync().execute();
albumAdapter=new LazyAdapter(TORiLTActivity.this, messages);
this.setListAdapter(albumAdapter);
bindToService();
//contentList.setFastScrollEnabled(true);
buttonMethode();
