Get reference to Views in my Android Activity

I have a LinearLayout comprising of a few Buttons and I add this to my activity in the onCreate(..) method with setContentView(R.l开发者_StackOverflowayout.myscreen). No surprises so far.

How do I get a reference to an iterator to these buttons? I'd like to add listeners to them but I'd rather not directly reference the Button's using their android:id.

Similar questions have been asked here and here but they don't quite answer my question.

Try something like this provide an id root_layout in xml to LinearLayout

LinearLayout mLayout = (LinearLayout) findViewById(R.id.root_layout);
    for(int i = 0; i < mLayout.getChildCount(); i++)
    {
        Button mButton = (Button) mLayout.getChildAt(i);
        mButton.setOnClickListener(this);
    }

Where mLayout is object of you Linear Layout and Your activity must implements OnClickListener and here goes general listener

@Override
public void onClick(View v)
{
    Button mButton = (Button)v;
    String buttonText = mButton.getText().toString();

}

NOTE: For this to work properly you Linear Layout must only contains button no other views

You should take a look at my answer here.

In short. I'd assign the buttons a listener by setting the onClick attribute in the XML layout on each Button.

Inside of your Activity you'll need a public method like the one below which basically is what you want to do in your listener.

public void myFancyMethod(View v) {
    // do something interesting here
}

If you want to go for accessing other elements you may try following syntax:

<ElementClass> <referencevariable> = (<ElementClass>) findViewById(R.id.<id_of_the_element>);

For Example:

TextView textView= (TextView) findViewById(R.id.t1); //I used t1 to refer my textview in the Layout.

This might work. Then you can use these views with their inbuilt methods to perform as many as work you want.
