Here are some interesting ones:

foreach
```
for ($i$ : $data$) {
    $cursor$
}
```

Toast

android.widget.Toast.makeText($className$.this, "$text$", Toast.LENGTH_SHORT).show();

todo
```
// TODO: $date$ $todo$ 
```

logi

android.util.Log.i(TAG, "$METHOD_NAME$: $content$");

The words surrounded by $ signs are places where things will be filled in automatically from the context or where the user can tab through to fill them in.

Use a Live Template

Just type in the abbreviation and tab through anything that you need to fill in.

Example:

logi

and I'm given this

Log.i(TAG, "myMethodName: |");

with the cursor located at the position I marked with the vertical line |.

Make you own Live Template

Just write the code, highlight it, and go to Tools > Save as Live Template.

Solution 3:

Go to Settings (File > Settings, or CTRLALT + S) then search for "Live Templates".

A template screen will be opened. You can see here all live templates and you can also create your own custom live templates.

It is important that you choose the correct template group to define your new template (e.g. "Android").

As an example, I will define a Toast method as a live template.

You can also click "use static import as possible" not to be handle importing stuff.
