Answer 1

In your xml add one button view

syntax:

<Button android:id="+@id/close"
     android:text="close"
     android:layout_margin="5sp" 
     android:layout_height="25sp"
     android:layout_width="25sp" 
     android:onClick="closeActivity" />

and inside your activity or java class

syntax:

public void closeActivity(View v){

 Intent intent=new Intent(currentclass.this,statingclass.class);
 startActivity(intent);
 finish();

Maybe an "Up" button is what you really need instead of a close button. From the official Android documentation: "Your app should make it easy for users to find their way back to the app's main screen. One simple way to do this is to provide an Up button on the app bar for all activities except the main one. "

Details are described here: https://developer.android.com/training/appbar/up-action.html

Use juzt have an x like image at the right top of corner. By pressing x image u can finish the activity.

XML:

        <ImageView
          android:id="@+id/close"
          android:layout_width="wrap_content"
          android:layout_height="wrap_content"
          android:align_parentRight="true"
          android:src="@drawable/closeimage"
          />

In Java Code:

       ImageView view=(ImageView)findViewById(R.id.close);
       view.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View arg0) {
             Intent intent=new Intent(currentclass.this,statingclass.class);
              startActivity(intent);// here u can start another activity or just call finish method to close the activity.
              finish();

        }
    });

make an Activity with Transparent theme in manifest like this:

<activity android:name=".MyDialogActivity" android:theme="@style/Theme.Transparent" />

and then define layout like this:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent" android:layout_height="fill_parent">
    <RelativeLayout android:orientation="vertical"
        android:layout_width="fill_parent" android:layout_height="fill_parent"
        android:layout_margin="15dp" android:padding="2dp">
        <!-- Contents will go here..-->
    </RelativeLayout>
    <Button android:layout_alignParentRight="true" android:text="X"
        android:textColor="#FFF" android:background="@drawable/round_button_background"
        android:gravity="center_vertical|center_horizontal"
        android:layout_margin="5dp" android:layout_height="25dp"
        android:layout_width="25dp" android:textSize="12sp" android:textStyle="bold"
        android:onClick="cancelActivity" />
</RelativeLayout>

and define a background for your close Button in drawable like this:

round_button_background.xml

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
        android:shape="oval">
    <solid android:color="#9F2200" />
    <stroke android:width="2dp" android:color="#FFF" />
</shape>
