Android中共享全局变量

MyApp.java:

public class MyApp extends Activity {/** Called when the activity is first created. */@Overridepublic void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.main);MyApplications appState = ((MyApplications) getApplicationContext());System.out.println("appState.getState()________" + appState.getState());}}

MyApplications.java:

import android.app.Application;public class MyApplications extends Application {private String myState = "hello from";public String getState() {return myState;}public void setState(String s) {myState = s;}}

配置文件:

<?xml version="1.0" encoding="utf-8"?><manifest xmlns:android="http://schemas.android.com/apk/res/android"package="com.example.aa" android:versionCode="1" android:versionName="1.0"><application android:name=".MyApplications" android:icon="@drawable/icon"android:label="@string/app_name"><activity android:name=".MyApp" android:label="@string/app_name"><intent-filter><action android:name="android.intent.action.MAIN" /><category android:name="android.intent.category.LAUNCHER" /></intent-filter></activity></application></manifest>

我就不做过多解释了,这样一些全部变量我们就不需要用Bundle传来传去了,直接获取Context对象,然后get,set就可以获取和设置.
希望对某些人有帮助!!!:)))))
