方法1:
通过不同Activity之间的消息传递机制实现数据共享
Activity1: Intent intent=new intent(Activity1.this,Activity2.clas); Bundle data=new data(); data.putString("name",name); intent.putExtras(data); StartActivity(intent); Activity2: Intent intent=getIntent(); Bundle data=intent.getExtras(); String name=data.getString("name);
方法2:
将需要共享的变量声明为public static类型
方法3:
新建Application的子类,在该类中声明共享的变量
class MyApp extends Application { private String myState; public String getState() { return myState; } public void setState(String s) { myState = s; } }
在AndroidManifest.xml的application加个name属性就可以了,如下面所示:
<application android:name=".MyApp" android:icon="@drawable/icon" android:label="@string/app_name">
使用时:
class Blah extends Activity { @Override public void onCreate(Bundle b){ ... MyApp appState = ((MyApp)getApplicationContext()); String state = appState.getState(); ... } }
