Hey all,
I'm building my first Android app, and it's pretty confusing. I'm
picking it up pretty well (or at least the minimal stuff I need to
know at this point), but I'm having one fairly significant issue. I
haven't been able to figure out how to start a new activity.
I know to create an intent: Intent launchSuccess = new Intent()
and I know to call startActivity(Intent intentname)
However, I'm not sure what to send into Intent() or what I have to do
in AndroidManifest.xml to get it to work.
Here's what I have:
--------------------------------------------------------------------------------------------
AndrAIM.java
--------------------------------------------------------------------------------------------
public class AndrAIM extends Activity {
/** Called when the activity is first created. */
Intent launchSuccess = new Intent(AndrAIM.this, Success.class);
// Create an anonymous class to act as a button click listener.
private OnClickListener sign_in_listener = new OnClickListener()
{
public void onClick(View v)
{
getInfo();
}
};
@Override
public void onCreate(Bundle icicle) {
super.onCreate(icicle);
setContentView(R.layout.main);
Button sign_in = (Button)findViewById(R.id.sign_in);
sign_in.setOnClickListener(sign_in_listener);
}
public void getInfo(){
final EditText passwordField = (EditText)
findViewById(R.id.password);
String password = passwordField.getText().toString();
final EditText unameField = (EditText)
findViewById(R.id.username);
String username = unameField.getText().toString();
if (validateLogin(username, password))
startActivity(launchSuccess);
else {
TextView tv = new TextView(this);
tv.setText("login failed!" + "\n" + "username: " +
username + "\n" + " password: " + password);
setContentView(tv);
}
}
public boolean validateLogin(String uname, String pword){
if(uname.equals("username1"))
if(pword.equals("password1"))
return true;
return false;
}
}
--------------------------------------------------------------------------------------------
main.xml

The following is Success's entry in AndroidManifest.xml
<activity android:label="@string/app_name" android:name="Success">
<intent-filter>
<action android:name="com.straightforwardcode.action.Success.MAIN">
</action></intent-filter></activity>
Any help would be greatly appreciated.
Thanks!
I have Success.java (which is the activity that I want to load) and
Success.xml, which defines its layout.
Essentially, I need to know what to do to get Success.java to load
