Question

我想从Fragment的所有视图中收集所选单选按钮中的数据并将其发布到服务器，我该如何收集数据？至少有人可以帮我吐司吗？

注意：此时我已经在一个屏幕上执行此操作，但我想要所有屏幕的集体数据。

吐司

Button myButton = (Button) layoutView.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();
                        Log.d("Button", "Text 1 : " + text1);
                    }

                    if (radioGroup2.getCheckedRadioButtonId() != -1) {
                        text2 = btn2.getText().toString();
                        Log.d("Button", "Text 2 : " + text2);
                    }


                    Toast.makeText(
                            thiscontext,
                            "Data Posting : APPLICATION : "
                                    + text1 + " \nDEVICE : " + text2,
                            Toast.LENGTH_LONG).show();


                }
            });

Answer 1

在每个片段中添加一个公共方法，例如

public HashMap<String, Boolean> getRadiosStatus{
    //TODO put every radio button's status to hashmap and return it.
}

然后，在活动中调用此方法。您可以通过调用所有相同的方法从所有片段中获取所有状态。

如何从Fragment中的不同视图中收集值？
