Android中不同的Activity之间的传值方式(Main为当前Activity,Login为目标Activity)
1、使用Intent
Intent intent = new Intent(Main.this, Login.class);
intent.putExtra("loginName", "rubekid");
2、使用 静态变量
Person person = new Person();
person.setName("rubekid");
person.setAge(13);
Login.person = person;
在Login里面定义静态变量
public static Person person;
3、剪切板(Clipboard)
Main中
ClipboardManager clipboardManager = (ClipboardManager)getSystemService(Context.CLIPBOARD_SERVICE);
clipboardManager.setPrimaryClip(ClipData.newPlainText("loginName", "rubekid"));
Login中
ClipboardManager clipboardManager = (ClipboardManager) getSystemService(Context.CLIPBOARD_SERVICE);
clipboardManager.getPrimaryClip().getItemAt(0).getText();
4、使用Application
public class MyApp extends Application{ private String name; public String getName() {
return name;
} public void setName(String name) {
this.name = name;
} @Override
public void onCreate() {
// TODO Auto-generated method stub
super.onCreate();
setName("测试");
}
}
Main中:
myApp = (MyApp)getApplication();
myApp.setName("rubekid");
Login中:
MyApp myApp = (MyApp) getApplication();
loginName.setText(myApp.getName());
