添加 setText() 时强制关闭
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() 时应用程序工作正常
the following is my code :
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){ }
});
But I get the app to force close , when remove setText() the app works fine

您陷入了
afterTextChanged方法中，因为在您setText之后，它被再次调用，一次又一次......您必须找到另一种方法，如何/何时附加“-”字符。You are getting stuck in your
afterTextChangedmethod, because right after yousetText, it is called again, and again, and again... You have to find another way, how/when to append the "-" character.请检查我不久前问过的这个问题。这很像你的问题：
