我也遇到过同样的问题，并不断得到stackOverflow异常，我提出了以下解决方案。

edt_amnt_sent.addTextChangedListener(new TextWatcher() {    
    @Override
    public void afterTextChanged(Editable s) {
        if (skipOnChange)
            return;

        skipOnChange = true;
        try {
            //method
        } catch (NumberFormatException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } finally {
            skipOnChange = false;
        }
    }
});

edt_amnt_receive.addTextChangedListener(new TextWatcher() {

    @Override
    public void afterTextChanged(Editable s) {

        if (skipOnChange)
            return;

        skipOnChange = true;
        try {
            //method
        } catch (NumberFormatException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } finally {
            skipOnChange = false;
        }
    }
});

skipOnChange = false;

我写了自己的扩展，对我很有帮助。(芬兰湾的科特林)

你可以这样写:

editText.customAfterTextChanged { editable -> 
    //You have accessed the editable object. 
}

我的分机号:

fun EditText.customAfterTextChanged(action: (Editable?)-> Unit){
    this.addTextChangedListener(object : TextWatcher {
       override fun beforeTextChanged(p0: CharSequence?, p1: Int, p2: Int, p3: Int) {}
       override fun onTextChanged(p0: CharSequence?, p1: Int, p2: Int, p3: Int) {}
       override fun afterTextChanged(editable: Editable?) {
        action(editable)
    }
})}

我知道这很旧了，但某天有人可能会再次看到它。

I had a similar problem where I would call setText on a EditText and onTextChanged would be called when I didn't want it to. My first solution was to write some code after calling setText() to undo the damage done by the listener. But that wasn't very elegant. After doing some research and testing I discovered that using getText().clear() clears the text in much the same way as setText(""), but since it isn't setting the text the listener isn't called, so that solved my problem. I switched all my setText("") calls to getText().clear() and I didn't need the bandages anymore, so maybe that will solve your problem too.

试试这个:

Field1 = (EditText)findViewById(R.id.field1);
Field2 = (EditText)findViewById(R.id.field2);

Field1.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) {
      Field2.getText().clear();
   }
  });

Field2.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) {
     Field1.getText().clear();
   }
  });

在将另一个EditText设置为空之前检查字符串。如果Field1为空，为什么需要再次更改为("")?所以你可以用s.l end()或任何其他解决方案检查你的字符串的大小

另一种检查字符串长度的方法是:

String sUsername = Field1.getText().toString();
if (!sUsername.matches(""))
{
// do your job
}

etSearch.addTextChangedListener(object : TextWatcher {
     override fun beforeTextChanged(p0: CharSequence?, p1: Int, p2: Int, p3: Int) {
          TODO("Not yet implemented")
     }

     override fun onTextChanged(p0: CharSequence?, p1: Int, p2: Int, p3: Int) {
          TODO("Not yet implemented")
     }

     override fun afterTextChanged(p0: Editable?) {
          TODO("Not yet implemented")
     }
})
