Androidandroid Program hints and message button response events

First, the interface XML joins the button response function android:onclick="Onmyclick"

    <button        android:id= "@+id/button1"        android:layout_width= "wrap_content"        android:layout_height= " Wrap_content "        android:layout_alignleft=" @+id/textview1 "        android:layout_below=" @+id/textview1        " android:layout_margintop= "30DP"        android:onclick= "Onmyclick"          android:text= "button"/>

You can then add the response function to the Java code file.

public void Msg1 ()   {     toast toast = new Toast (this);     Toast Toast1 = Toast.maketext (This, "Hello World", Toast.length_long);     Toast1.show ();       }  public void Onmyclick (View v)   {      Msg1 ();//message prompt display}  

This method of adding the response function is simple, it feels that the code readability is much better than adding setonclicklistener listener User click operation.

Setonclicklistener This method allows more code. Too wordy.
