How to bring activity to front using finish from another activity

Question

i have two activities: A and B.

from A to B:

onCreate

Context context = this;

onClick

Intent i = new Intent(context,B.class);
startActivity(i);

from B to A: (if B has a button to return to A)

button.setOnClickListener(new View.OnClickListener(){
   public void onClick(View v){
      finish();
   }
});

But if the flow is like:

A call B, the user that is watching B clicks Home button and click again B from launched activities and clicks the button to call finish(), it goes to Home and not to my first activity A. How can i do it?

EDIT:

flow

1. A->B // with startActivity(Intent);
2. B->Home // clicking home button on device
3. Home->B // clicking my app from launched activities
4. B.finish() -> Home and not A // finish or onBackPressed do the same

Answer 1

can you try this :-

WHY ARE YOUR USING getApplicationContext() instead of use this or Activity A name.

A ->B

 Intent i = new Intent(yourcurrentActivity,B.class);
 startActivty(i);

B ->A

call finish()

update if you are using this:- remove it

android:noHistory="true";

Answer 2

call

onBackPressed();

instead of

finish();

Answer 3

Try this:

public void startActivityForResult (Intent intent, int requestCode)

Answer 4

Try this:

startActivity(new Intent(B.this,B.class));

and finish() in activity A as

// in your activity A
Intent i = new Intent(getApplicationContext(),B.class);
startActivity(i);
finish();

and

public void OnBackPressed()
{
finish();
}

check below code: i have 3 activity : MainActivity, A_Acvitiy, B_actiivty (Hope its worked as per your req..)

package com.example.androidtest;

import android.os.Bundle;
import android.app.Activity;
import android.content.Intent;
import android.view.Menu;
import android.view.View;

public class MainActivity extends Activity {

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

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

    public void callActivity(View v) {
        if (v.getId() == R.id.button1) {
            // A
            startActivity(new Intent(MainActivity.this, A_activity.class));
        }

        if (v.getId() == R.id.button2) {
            // B
            startActivity(new Intent(MainActivity.this, B_activity.class));
            if (GeneraClass.isFormB) {
                            GeneraClass.isFormB = false;
                finish();
            }
        }
    }
}

A_activity:

package com.example.androidtest;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;

public class A_activity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setContentView(R.layout.a_layout);
    }

    public void callActivity(View v) {
        if (v.getId() == R.id.button1) {
            // B
            startActivity(new Intent(A_activity.this, B_activity.class));
                 finish();
        }

    }

}

b_activity:

package com.example.androidtest;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;

public class B_activity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);

        setContentView(R.layout.b_layout);
    }

    public void callActivity(View v) {
        if (v.getId() == R.id.home) {
            // home
            GeneraClass.isFormB = true;
            startActivity(new Intent(B_activity.this, MainActivity.class));
            finish();
        }

    }
}

my extra class:

package com.example.androidtest;

public class GeneraClass {

    public static boolean isFormB = false;
}

So, Home-->A(finish)-->B--->Home(if from b then finish)-->B-->Back--> Home --->Back--> exit App
