Two ways to listen/response input event in Android

android mobile

Click Event

1. Do this in XML.
   Notice: Do not do this for event in fragment, Why?

//In your view xml file, set the onClick property
android:id="@+id/button1"
android:onClick="someMethod"
//In your Activity, write the implementation of someMethod
public void someMethod(View v) {
    int id = v.getId();
    if (id == R.id.button1) {
        //Do sth to response click event
    }
}

1. Implement onClickListener()

Button btn = (Button) findViewById(R.id.mybutton);
btn.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        someMethod(v);
        //or Do sth
    }
});
// some more code
public void someMethod(View v) {
    // does something very interesting
}
