Question

I want to make password protected android app, but when in this simple program system is not matching two strings.

package com.pokmgr;

import android.os.Bundle;
import android.app.Activity;
import android.content.Intent;
import android.text.Editable;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;

public class MainPM extends Activity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.pm_layout);

        final EditText pin = (EditText) findViewById(R.id.pinET); 
        final String pass = pin.getText().toString();
        final String code = "ajaj";
        Button enter = (Button) findViewById(R.id.enterBtn);
        enter.setOnClickListener(new OnClickListener() {

            public void onClick(View v) {
                // TODO Auto-generated method stub
                if (pass.equals(code)) {
                    Intent in = new Intent(MainPM.this, Menu.class);
                    startActivity(in);
                }
                else {
                    Intent in = new Intent(MainPM.this, Menu2.class);
                    startActivity(in);
                }

            }
        });
    }

    /*@Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.pm_layout, menu);
        return true;
    }*/
}

I have made Menu and Menu2 class, but every time Menu2 class is accessed. Even if I enter same pass that is “ajaj” [in this code to test]
i have defined both activities in manifest file.

Can’t understand why pass.eqals(code) is not working

Answer 1

The problem is that you are setting pass to the contents of the EditText when the activity gets created. Instead you have to retrieve the contents of your EditText inside the OnClickListener.

Like this:

public void onClick(View v) {
    final String pass = pin.getText().toString();
    if (pass.equals(code)) {
        // do something
    } else {
        // do something different
    }
}
