Question

I have a created a screen for which it will ask the password and compare with the inbuilt password and launch another screen but I am unable to launch the activity even if I give the correct password. Any help will be greatly appreciated.

 public class MainActivity extends Activity {

     public static String lock = "vamsi";
     public static String locker;
     EditText et;
     Button b;

     @Override
     public void onCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);

         setContentView(R.layout.activity_main);
         et = (EditText) findViewById(R.id.editText1);
         b = (Button) findViewById(R.id.button1);
         locker = et.getText().toString();

         b.setOnClickListener(new View.OnClickListener() {
             public void onClick(View arg0) {
                     if (locker.equals(lock)) {
                     Intent intent = new Intent("screen");

                     startActivity(intent);
                 }
             }
         });
    }
}

Write Following line

Intent intent = new Intent (getApplicationContext(), FileName.class);

instead of

Intent intent = new Intent("screen");

Where FileName is the name of that activity which do you want to open in Onclick Method.
