android - 添加 setText() 时强制关闭

Question

以下是我的代码：

name = (EditText)findViewById(R.id.editText1);
        name.addTextChangedListener(new TextWatcher(){
         public void afterTextChanged(Editable s) {


             name.setText(s.toString()+"-");
                }
 public void beforeTextChanged(CharSequence s, int start, int count, int after){ }
 public void onTextChanged(CharSequence s, int start, int before, int count){ }
            });

但是我让应用程序强制关闭，当删除 setText() 应用程序工作正常

Answer 1

你被困在你的afterTextChanged方法中，因为在你之后setText，它被一次又一次地调用......你必须找到另一种方法，如何/何时附加“-”字符。

Please check this question I asked some time ago. It's a lot like your question:
