Android应用程序因java.lang.StackOverflower错误而失败

我正在制作一个android程序，由于stackoverflow错误而失败。我已附上我的代码。我正在使用android studio。我相信它之所以循环是因为addTextChangedListener，但我不明白它为什么这样做

我的代码：

    rb1 = (RadioButton) findViewById(R.id.radioButtonCFM);
    rb2 = (RadioButton) findViewById(R.id.radioButtonAC);

    rb1.setOnClickListener(new RadioGroup.OnClickListener() {
         public void onClick(View v) {
             EditText e1 = (EditText) findViewById(R.id.editText);
             String sUsername1 = e1.getText().toString();
             if (TextUtils.isEmpty(sUsername1)) {
                 e1.setError("The item cannot be empty.");
                 return;
             }

             EditText e2 = (EditText) findViewById(R.id.editText2);
             String sUsername2 = e2.getText().toString();
             if (TextUtils.isEmpty(sUsername2)) {
                 e2.setError("The item cannot be empty.");
                 return;
             }

             EditText e3 = (EditText) findViewById(R.id.editText3);
             String sUsername3 = e3.getText().toString();
             if (TextUtils.isEmpty(sUsername3)) {
                 e3.setError("The item cannot be empty.");
                 return;
             }

             e1.addTextChangedListener(new TextWatcher() {

                 public void afterTextChanged(Editable s) {
                 }

                 public void beforeTextChanged(CharSequence s, int start,
                                               int count, int after) {
                 }

                 public void onTextChanged(CharSequence s, int start,
                                           int before, int count) {
                     EditText e1 = (EditText)findViewById(R.id.editText);
                     EditText e2 = (EditText)findViewById(R.id.editText2);
                     EditText e3 = (EditText)findViewById(R.id.editText3);
                     volume = Double.parseDouble(e1.getText().toString());
                     cfm = Double.parseDouble(e2.getText().toString());
                     ac = Double.parseDouble(e3.getText().toString());
                     TextView t1 = (TextView) findViewById(R.id.editText3);
                     volume = Double.parseDouble(e1.getText().toString());
                     cfm = Double.parseDouble(e2.getText().toString());
                     ac = cfm * 60 / volume;
                     t1.setText(Double.toString((double) Math.round(ac * 100000) / 100000));
                 }
             });


             e2.addTextChangedListener(new TextWatcher() {

                 public void afterTextChanged(Editable s) {
                 }

                     ac = cfm * 60 / volume;
                     t1.setText(Double.toString((double) Math.round(ac * 100000) / 100000));
                 }
             });

         }});

     rb2.setOnClickListener(new RadioGroup.OnClickListener() {

监视

R.id.editText3

输入的TextWatcher正在修改

R.id.editText2

的文本，而

R.id.editText3

的文本又在修改。通过这种方式，您将获得对

onTextChanged（…）

的无限调用，请尝试在您的活动中添加以下行：

@Override

public boolean onKeyDown(int keyCode, KeyEvent event)
    {
        if ((keyCode == KeyEvent.KEYCODE_BACK))
        {

            finish();

        }
        return super.onKeyDown(keyCode, event);
    }

---

您正在重复调用findViewById（）。只需创建所有视图字段，并在setContentView（）之后的onCreate（）中“查找”它们

我注意到你打电话来了

TextView t1 = (TextView) findViewById(R.id.edittext3);

---

不需要有指向同一视图的重复指针。简化代码，确保所有变量都指向正确的目标，并且TextWatcher不会自行触发。

使用LogCat检查Java堆栈跟踪，以查看无限递归的确切位置：我尝试过检查它，可以看出它在重复。但不幸的是，我不太明白。你怎么把日志贴在这里？太长了。我复制并粘贴到我的主要活动中。但是，它没有解决java.lang.StackOverflower错误。这是怎么回事？为什么你不把它链接到texbox？它似乎没什么作用，但我有rb1.setOnClickListener和rb2.setOnClickListener，它们将侦听器分开。它假设在单击rb1.setOnClickListener时基于R.id.editText1和R.id.editText2更改R.id.editText3。当单击rb2.setOnClickListener时，它假设根据R.id.editText1和R.id.editText3更改R.id.editText2。那么，即使单击了rb1.setOnClickListener，它仍然在侦听R.id.editText3吗？我该如何避开这件事，让它不听？
