Question

我有一个布局，它有一个动态生成的单选按钮和一个提交按钮，它可以在SUBMIT按钮上获取所选单选按钮的值。现在我想为（n）页创建一个动态生成的滑动视图，我可以为不同的页面显示相同的布局。以下是我的方法和工作代码。提前致谢

MainActivity.java

public class MainActivity extends Activity {

    private String[] application = { "ABC", "DEF", "GHI", "HIJ" };

    private RadioGroup radioGroup2;

    private String text2;
    RadioButton button1;
    RadioButton button2;
    Button selectall;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        checkButtonClick();
        drawRadiobuttons();

    }

    private void checkButtonClick() {

        Button myButton = (Button) findViewById(R.id.findSelected);
        myButton.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {

                StringBuffer responseText = new StringBuffer();
                responseText.append("");

                // Get selected radiobuttons
                if (radioGroup1.getCheckedRadioButtonId() != -1) {
                    text1 = btn.getText().toString();

有人可以帮忙吗？

Answer 1

如果我找到你，sliding views你的意思是ViewPager。您可以参数化ViewPager的适配器，即将页数传递给Adapter的构造函数。请查看FragmentPagerAdapter或FragmentStatePagerAdapter。

在您的按钮中，单击侦听器计算您需要的页数（n）。
将其Intent传递给新Activity。
实施您自己的FragmentViewPager并将n值传递给其构造函数。
...
PROFIT！
