Lesson for Android Programming Beginners :
Step 1 : Create Button
In your layout.xml file create a button view and set the attribute : android:onClick = "displayToastMsg"
<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"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context="com.example.toastexample.MainActivity" >
<Button
android:id="@+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:onClick="displayToastMsg"</b>
android:text="Display Toast Message!" />
</RelativeLayout>
Step 2 : Create Toast Method
Now let's create a method that displays a Toast message when the button is being clicked. Let the method takes in one parameter i.e. the Message to be displayed as String.
public void toastMsg(String msg) {
Toast toast = Toast.makeText(this, msg, Toast.LENGTH_LONG);
toast.show();
}
Step 3 : Create Button Click Listener Method
Now let's implement Button click Listener that will be called when the button is clicked. We call the toastMsg() function to display the Toast Message.
public void displayToastMsg(View v) {
toastMsg("Hello how are you today!!");
}
Step 4 : Run the App :
