Question

我正在开发一个测验，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想要另一个类（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？请帮帮我们..非常感谢你们！我希望我的问题很清楚..我真的很感谢你的帮助！

的 Question1.java 的

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();


        }

    }

}

尝试使用片段而不是活动，并且您不必为每个新片段使用start活动。要更改屏幕，您只需执行删除旧片段并添加新片段的事务。此机制也是比使用多个活动显示每个不同的问题更有效。

如何在没有调用android中的startactivity的意图活动？
