NewTweetActivity.java には、次のものがあります。
@Override
public void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.newtweet);
listenToChange();
}
public void listenToChange(){
TextView cEditText = (TextView) findViewById(R.id.tweetCountTextView);
EditText tView = (EditText) findViewById(R.id.tweetComposerEditText);
tView.addTextChangedListener(new TextWatcher() {
public void afterTextChanged(Editable s) {
int len = (140 - s.length());
cEditText.setText(len);
}
public void beforeTextChanged(CharSequence arg0, int arg1,
int arg2, int arg3) {
// TODO Auto-generated method stub
}
public void onTextChanged(CharSequence arg0, int arg1, int arg2,
int arg3) {
// TODO Auto-generated method stub
}
});
}
ただし、cEditTextを final として宣言するように求められますが、そうすると、newtweet レイアウトの読み込みに失敗します。
cEditText宣言をの中に入れるとafterTextChanged、レイアウトが読み込まafterTextChangedれますが、(EditText を入力して) トリガーすると、次のようになります。

cEditTextのsetTextメソッドを文字列 (「cats」など) で呼び出すと、機能します。
何か案は？
