從額外的信息另一類啓動級的android

Question

我想問是否可以從另一個非活性類啓動一個非活性類

即：

public class nubmerOne { 
    String data = "send me please"; 
    public String getInfo(){ 

     if (/*something happens*/){ 
      //start Class numberTwo with some data 
     } 
    return ""; 
    } 
} 


public class numberTwo { //this class is started when condition in class One is true 
String dataPlus = ""; 
    public String dosomething(){ 
     //started from class numberOne and get data 

    dataPlus = data + ""; 
    return dataPlus; 
    } 
} 

我知道這是可能的BroadcastReceiver，擴展活動和服務類，芽可能在兩個類內做到這一點？

我不知道我理解你的問題，但這看起來像只是經典的Java。

如果條件滿足，您的第一個類必須創建第二個類的實例，並在第二個類的構造函數中傳遞數據。

public class nubmerOne { 
    String data = "send me please"; 
    public String getInfo(){ 

     if (/*something happens*/){ 
      //start Class numberTwo with some data 
      NumberTwo numberTwo = new NumberTwo (data); 
      numberTwo.doSomething(); 
     } 
    return ""; 
    } 
} 


public class NumberTwo { //this class is started when condition in class One is true 
    private String data; 

    public NumberTwo (String data){ 
     this.data = data; 
    } 
String dataPlus = ""; 
    public String dosomething(){ 
     //started from class numberOne and get data 

    dataPlus = data + ""; 
    return dataPlus; 
    } 
} 

希望我幫了忙。
