Guidelines

While working with Views/UI elements always give them an id

<Button android:id = “@+id/button” android:layout_width = “fill_parent” android:layout_height = “wrap_content” android:text = “Press Me”/>

width and height are compulsory to declare. id's are to be declared if they are to be manipulated.

Refer to your layout in your src with this

setContentView() : … setContentView(R.layout.file_name);

Refer to the Button declared earlier

Button button: … (inside onCreate()) button = (Button) findViewById(R.id.button);

Manipulating the Button

button.setOnClickListener( … );

Displaying the Short Popup

Toast.makeText(getApplicationContext(), “This is a short popup message”, Toast.LENGTH_SHORT).show();

R class found under gen

Auto-generated: DO NOT EDIT

Contains ID of the project resources

Use findViewById and Resources object to get access to the resources:

E.g. Button = (Button)findViewById(R.id.button); E.g. getResources().getString(R.string.hello);
