Android中应用享元全局变量

在Intent中来回的传一些所谓的全局变量实在苦手，上网搜了搜，果然有省事的方案（http://*.com/questions/708012/android-how-to-declare-global-variables）可以用继承Application来享元~~直接贴代码~

 

 

public class ShareContext extends Application {
	private PHPRPC_Client client;

	public PHPRPC_Client getClient() {
		return client;
	}

	public void setClient(PHPRPC_Client client) {
		this.client = client;
	}
}

 

 然后在AndroidManifest.xml中设置name属性

 

<application android:name=".ShareContext" android:icon="@drawable/icon" android:label="@string/app_name">

设置享元：

 

ShareContext shareContext = ((ShareContext)getApplicationContext());
shareContext.setClient(client);

 

 读取享元：

 

ShareContext shareContext = ((ShareContext)getApplicationContext());
PHPRPC_Client client = shareContext.getClient();

 好东西~~直接省了很多事！！
