[Android] 1, page jump + button monitoring

A total of 2 layout:main.xml and Other.xml;2 Activity:mainactivity.java,otheractivity.java

Rewrite OnCreate in mainactivity, line 6th set Button Listen ~

1  Public voidonCreate (Bundle savedinstancestate) {2     Super. OnCreate (savedinstancestate);3 Setcontentview (r.layout.main);4LOG.V ("Mainactivity", "OnCreate");5BTN =(Button) Findviewbyid (R.ID.MAIN_BTN);6Btn.setonclicklistener ( This);7     //this.finish ();//End Current Mainactivity8}

Here is the implementation of the button listener: that is, when the button is pressed, jump to another page:

1 @Override2  Public voidOnClick (View arg0) {3     if(arg0 = =btn) {4Intent Intent =NewIntent ();5Intent.setclass ( This, Otheractivity.class);6          This. StartActivity (intent);7     }8}

Another activity is similar:

 1  public  void       OnCreate (Bundle savedinstancestate) { 2  super  .oncreate (savedinstancestate);  3   Setcontentview (r.layout.other);  4  log.v ("mainactivity", "OnCreate"  5  btn =6  Btn.setonclicklistener (this  " Span style= "color: #000000;" >); 7 } 

1  Public void OnClick (View arg0) {2     if (arg0 = = btn) {3          This . Finish (); 4     }5 }

Some people will think otheractivity why that look, for the moment I do not know, first put his XML file:

1 <?XML version= "1.0" encoding= "Utf-8"?>2 <LinearLayoutxmlns:android= "Http://schemas.android.com/apk/res/android"3 android:orientation= "vertical"4 Android:layout_width= "Fill_parent"5 Android:layout_height= "Fill_parent"6     >7 <TextView8     Android:layout_width= "Fill_parent" 9 Android:layout_height= "Wrap_content" Ten Android:text= "@string/otheractiviy_hello" One     /> A <Button -     Android:layout_width= "Fill_parent"  - Android:layout_height= "Wrap_content"  the Android:text= "@string/otheractiviy_btnclose" - Android:id= "@+id/other_btn" -     /> - </LinearLayout>
