Custom Dialog in Android

Creating a Custom Dialog in Android

I create a new android application project called "Custon_dialog"

Then I need to create a custom layout for my custom dialog and for this I create a new xml file called "dialog.xml"

In my custom dialog i want to show a picture and  some texts.

So, i drag a picture in my drawable folder.

dialog.xml

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

    android:layout_width="match_parent"

    android:layout_height="match_parent"

    android:orientation="vertical" >

    <ImageView

        android:id="@+id/imageView1"

        android:layout_width="110dp"

        android:layout_height="160dp"

        android:contentDescription="@string/todo"

        android:padding="20dp"

        android:src="@drawable/android" />

    <TextView

        android:id="@+id/textView1"

        android:layout_width="170dp"

        android:layout_height="211dp"

        android:text="@string/i_love_android" 

        android:textSize="25sp"/>

</LinearLayout>

Now I write these codes in activity_main.xml.

activity_main.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

    xmlns:tools="http://schemas.android.com/tools"

    android:layout_width="match_parent"

    android:layout_height="match_parent"

    tools:context=".MainActivity" >

    <Button

        android:id="@+id/button1"

        android:layout_width="wrap_content"

        android:layout_height="wrap_content"

        android:layout_alignParentLeft="true"

        android:layout_alignParentTop="true"

        android:layout_marginLeft="78dp"

        android:layout_marginTop="28dp"

        android:text="@string/show" />

   

</RelativeLayout>

MainActivity.java

public class MainActivity extends Activity {

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

Button b = (Button) findViewById(R.id.button1);

b.setOnClickListener(new View.OnClickListener() {

@Override

public void onClick(View arg0) {

final Dialog custom = new Dialog(MainActivity.this);

custom.setContentView(R.layout.dialog);

custom.setTitle("check it out");

custom.show();

 

}

});

}

I run my project and it looks like this:
