<EditText android:layout_width="fill_parent"
            android:layout_height="wrap_content"

Here the android:lines attribute is used to set the no. of lines visible. The android:gravity attribute sets the cursor to top left corner.

The following codes will do the trick.

Consider a display object dispObj and a function eventFun(event), then

For Adding event listener

dispObj:addEventListener("touch", eventFun)  // This will add the touch event to dispObj

For Removing event listener

dispObj:removeEventListener("touch", eventFun)  // This will remove the touch event from dispObj

Consider a display object dispobj. Now we can scale the display object using two methods:

Method 1:

dispobj:scale(0.5,0.5)

Method 2:

dispobj:xScale = 0.5

dispobj:yScale = 0.5

The following code is used to split a string in Corona.

local stringobj = "hai,hello,man"

local stringarray = str.split(stringobj, ",")

Here in this code, the string stringobj will be split into an array named stringarray with values hai,hello and man. Here ‘,’ is used as the split string.

The following code is used to create activity indicator in Corona.

native.setActivityIndicator( true );

Based on the platform in which the app is run the nature of the activity indicator changes automatically.

To remove the activity indicator, use the following code.

native.setActivityIndicator( false );

We know about the Linnkify class in android. Have you ever wondered that we can use this same class to add a market link?
Here is a sample code for the same.


TextView txtView = (TextView) findViewById(R.id.linkme);
