如何在不调用android中的startactivity的情况下进行intent活动

Question

im正在开发一个测试，其中在java类中，我想在不使用startactivity的情况下单击下一个按钮后设计另一个类（问题），或者是否可以使用另一种方法调用另一个活动来传递另一个活动？伙计们，请帮帮我。。非常感谢！我希望我的问题很清楚。。我真的很感谢你的帮助！

问题1.java

public class Question1 extends Activity implements OnClickListener
{
int Scorecount = 0;
//private RadioGroup rgp;
private RadioButton rb1;
private RadioButton rb2;
private RadioButton rb3;
private Button b1;
//private TextView t1;
int currentQuestion = 0;
Toast t;

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.startquiz);
Scorecount = getIntent().getIntExtra("score",0);
rb1=(RadioButton)findViewById(R.id.option1);
rb2=(RadioButton)findViewById(R.id.option2);
rb3=(RadioButton)findViewById(R.id.option3);
b1=(Button)findViewById(R.id.selected);
b1.setOnClickListener(this);
//rgp=(RadioGroup)findViewById(R.id.QueGroup1);

//t1=(TextView)findViewById(R.id.txtdisplayanswer);
}
@Override
public void onClick(View v) {

    if(v == b1)
    {
        if(rb1.isChecked() || rb2.isChecked() || rb3.isChecked())
        {
            if(rb1.isChecked())
            {
                Scorecount++;
                Toast.makeText(getApplicationContext(),"Your answer is correct!",
                        Toast.LENGTH_LONG).show();
                /*LinearLayout layout = (LinearLayout) t.getView();
                layout.setGravity(Gravity.CENTER);
                layout.setBackgroundResource(R.drawable.toastgreen);
            //t1.setText("Your answer is correct!"  +rb1.getText());*/
            }
        /*
        if(rb2.isChecked() == true)
            //t1.setText("Your wrong, the correct answer is: "+rb1.getText());
        if(rb3.isChecked() == true)
            //t1.setText("Your wrong, the correct answer is: "+rb1.getText());*/
    else {
        // do nothing
        Toast.makeText(getApplicationContext(),"Your answer is wrong! The correct answers is:    " + rb1.getText(),
                Toast.LENGTH_LONG).show();
        /*LinearLayout layout = (LinearLayout) t.getView();
        layout.setGravity(Gravity.CENTER);
        layout.setBackgroundResource(R.drawable.toastred);*/
    }
            //Intent i = new Intent(this,Question2.class);
            Intent i= getIntent();
            i.putExtra("score", Scorecount);
            startActivity(i);
            finish();

        }
    }
}

尝试使用fragment而不是activity，并且不必对每个新的fragment使用start activity。要更改屏幕，您只需执行删除旧片段并添加新片段的事务。这种机制也比使用多个活动来显示每个不同的问题更有记忆效率。
