We see situations while developing an app that we need to put certain things inside the Android Dialog box. Here is how we can achieve the same:

First, create the layout that you want to give to the Dialog. Below is a sample layout:

custom_dialog.xml

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@android:color/white"
    android:gravity="center_horizontal"
    android:orientation="vertical" >

    <RelativeLayout
        android:layout_width="fill_parent"
        android:layout_height="55dp"
        android:background="@drawable/header" 
        android:padding="1dp">

        <ImageView
            android:id="@+id/close_dialog"
            android:layout_width="52dp"
            android:layout_height="52dp"
            android:layout_alignParentLeft="true"
            android:layout_centerVertical="true"
            android:layout_marginLeft="10dp"
            android:onClick="onClick"
            android:src="@drawable/backbtn" />
    </RelativeLayout>

    <LinearLayout
        android:id="@+id/buttons"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_marginTop="25dp"
        android:gravity="center"
        android:orientation="horizontal" >

        <ImageView
            android:id="@+id/retake"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:src="@drawable/fail_retake" />

        <ImageView
            android:id="@+id/addManually"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_marginLeft="30dp"
            android:src="@drawable/add_manually" />
    </LinearLayout>
</LinearLayout>

And below is the method that you can call to show the Dialog with custom layout we made above:

   void showCustomDialog()
    {
        final Dialog dialog = new Dialog(this, android.R.style.Theme_Black_NoTitleBar_Fullscreen);
        dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
        dialog.setCancelable(false);
        dialog.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);
        dialog.setContentView(R.layout.custom_dialog);

 ImageView use = (ImageView) dialog.findViewById(R.id.addManually);
    ImageView retake = (ImageView) dialog.findViewById(R.id.retake);
    ImageView closeImage = (ImageView) dialog.findViewById(R.id.close_dialog);
    use.setOnClickListener(new OnClickListener()
    {
        @Override
        public void onClick(View v) 
        {
            Intent intent = new Intent(CaptureActivity.this, AddManually.class);
            this.startActivity(intent);
            dialog.dismiss();
            this.finish();
        }
    });
    retake.setOnClickListener(new OnClickListener()
    {
        @Override
        public void onClick(View v) 
        {
            dialog.dismiss();         
        }
    });
    closeImage.setOnClickListener(new OnClickListener()
    {
        @Override
        public void onClick(View v) 
        {
            dialog.dismiss();         
        }
    }); 
    dialog.show();
}

We can use many buttons or images or any views inside the above layout according to our needs and perform various actions for further navigation using them.
