Question

我有四个活动（A，B，C，D），序列可以是任何类似的（取决于运行时的要求）

A类代码就像这样，我们从服务器api响应中获取活动名称并将其传递给公共类以移动到另一个活动 -

class A extends Activity{

   // Other Code of Activity 

    int backCount = getbackCountFromResponse();  // by calling any service

    String name = getActivityNameFromResponse(); // by calling any service

    Move m  = new Move(this);
    m.go(name);


    onBackPressed(){

        // What will be the code to move back according to number of back count
    }
}

B类代码就像这样，我们从服务器api响应中获取活动名称并将其传递给公共类以移动到另一个活动 -

class B extends Activity{

    int backCount = getbackCountFromResponse();  // by calling any service

    String name = getActivityNameFromResponse(); // by calling any service

    Move m  = new Move(this);
    m.go(name);

    onBackPressed(){

    // What will be the code to move back according to number of back count
    }
}

B类代码就像这样，我们从服务器api响应中获取活动名称并将其传递给公共类以移动到另一个活动 -

 class C extends Activity{

    // Other Code of Activity 


    int backCount = getbackCountFromResponse();  // by calling any service

    String name = getActivityNameFromResponse(); // by calling any service

    Move m  = new Move(this);
    m.go(name);

    onBackPressed(){

    // What will be the code to move back according to number of back count
    }

}

B类代码就像这样，我们从服务器api响应中获取活动名称并将其传递给公共类以移动到另一个活动 -

 class D extends Activity{

   // Other Code of Activity     

    int backCount = getbackCountFromResponse();  // by calling any service

    String name = getActivityNameFromResponse(); // by calling any service

    Move m  = new Move(this);
    m.go(name);

    onBackPressed(){

    // What will be the code to move back according to number of back count
    }

}

常用方法代码“go”移动到任何活动 -

 class Move {

     Context con;
     public Move(Context con){
           this.con = con;
      }


     public void go(String activityname)
     {

         Intent i = new Intent(con, activityname.class)
         this.con.startActivity(i);   

     }
}

我想从当前位置删除计数来自服务的活动数量，如何删除。

如果你想从活动堆栈中清除上一个任务，并希望在堆栈顶部进行另一项活动，那么你应该试试这个。

Intent intent = new Intent(this, AnotherActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(intent);

如果您不想清除以前的任务，只想将之前的活动放在前面，那么就像这样添加这两个标志。

Intent intent = new Intent(this, AnotherActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_BROUGHT_TO_FRONT);
intent.addFlags(Intent.FLAG_ACTIVITY_REORDER_TO_FRONT);
startActivity(intent);

希望它会对你有所帮助。
