Question

我正在为我的xml开发一个quiz.in的应用程序我有一个问题，4个选项（选项是textviews）以及上一个和下一个按钮。我做了上一个和下一个按钮。但我面临选择的问题。当我单击或选择一个问题的选项时，所有问题选项也会选择。如何控制这种行为？请任何人帮忙怎么做？

   if (v == rb1) {
        Toast.makeText(getApplicationContext(), rb1.getText().toString(), Toast.LENGTH_SHORT).show();
      //   quelay.setVisibility(View.INVISIBLE);
       // answer.setVisibility(View.VISIBLE);
        db.updateContact(question.getText().toString());
        setNext();
    if (v == rb2) {
        Toast.makeText(getApplicationContext(), rb1.getText().toString(), Toast.LENGTH_SHORT).show();
      //   quelay.setVisibility(View.INVISIBLE);
       // answer.setVisibility(View.VISIBLE);
        db.updateContact(question.getText().toString());
        setNext();

Answer 1

你可以试试这个。

 private View.OnClickListener mCorkyListener = new View.OnClickListener() {
        public void onClick(View v) {
            // do something when the button is clicked
            // Yes we will handle click here but which button clicked??? We don't know

            // So we will make
            switch (v.getId() /*to get clicked view id**/) {
                case R.id.rb1:

                     Toast.makeText(getApplicationContext(), rb1.getText().toString(), Toast.LENGTH_SHORT).show();
                    //quelay.setVisibility(View.INVISIBLE);
                    //answer.setVisibility(View.VISIBLE);
                     db.updateContact(question.getText().toString());
                     setNext();

                    break;
                case R.id.rb2:

                    Toast.makeText(getApplicationContext(), rb2.getText().toString(), Toast.LENGTH_SHORT).show();
                    //quelay.setVisibility(View.INVISIBLE);
                    //answer.setVisibility(View.VISIBLE);
                     db.updateContact(question.getText().toString());
                     setNext();

                    break;
                case R.id.rb3:

                    Toast.makeText(getApplicationContext(), rb3.getText().toString(), Toast.LENGTH_SHORT).show();
                    //quelay.setVisibility(View.INVISIBLE);
                    //answer.setVisibility(View.VISIBLE);
                     db.updateContact(question.getText().toString());
                     setNext();

                    break;

                case R.id.rb4:

                    Toast.makeText(getApplicationContext(), rb4.getText().toString(), Toast.LENGTH_SHORT).show();
                    //quelay.setVisibility(View.INVISIBLE);
                    //answer.setVisibility(View.VISIBLE);
                     db.updateContact(question.getText().toString());
                     setNext();

                    break;
                default:
                    break;
            }
        }
    };

Answer 2

试试这个，

ng-model="n.checked"

在两个条件中都显示 rb1.getText（）。toString（）。所以改变你的第二个条件部分，如

if (v == rb1) {
    Toast.makeText(getApplicationContext(), rb1.getText().toString(), Toast.LENGTH_SHORT).show();
   db.updateContact(question.getText().toString());
    setNext();
if (v == rb2) {
    Toast.makeText(getApplicationContext(), rb2.getText().toString(), Toast.LENGTH_SHORT).show();

    db.updateContact(question.getText().toString());
    setNext();

当一个textview在android中点击监听器时选择所有文本视图？
