在onCreate方法中TextWatcher的實現不起作用，我嘗試使用虛擬鍵盤和硬件鍵盤進行文本輸入，並嘗試了模擬器和真實設備上的代碼。似乎沒有任何工作。TextWatcher不能正常工作，出現什麼問題
我甚至改名佈局EditTexts和清理項目，重新構建它，沒有希望
什麼想法？
這裏是代碼
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.remarks);
getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
getWindow().addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
Intent i = getIntent();
Current_Language = i.getStringExtra("Lang");
Q1Rate = i.getFloatExtra("Q1Rate", 0f);
Q2Rate = i.getFloatExtra("Q2Rate", 0f);
Q3Rate = i.getFloatExtra("Q3Rate", 0f);
Q4Rate = i.getFloatExtra("Q4Rate", 0f);
Q5Rate = i.getFloatExtra("Q5Rate", 0f);
LoadSettings();
NextBtnState();
final EditText edt_PhoneNo = (EditText) findViewById(R.id.edt_Remarks_PhoneNo);
final EditText edt_Suggestions = (EditText) findViewById(R.id.edt_Remarks_Suggestion);
edt_Suggestions.addTextChangedListener(new TextWatcher() {
public void onTextChanged(CharSequence s, int start, int before, int count) {
}
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
}
public void afterTextChanged(Editable s) {
ShowToast("I Am Here Firas");
resetTimeout();
}
});
edt_PhoneNo.addTextChangedListener(new TextWatcher() {
public void onTextChanged(CharSequence s, int start, int before, int count) {
}
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
}
public void afterTextChanged(Editable s) {
ShowToast("I Am Here Firas");
resetTimeout();
}
});
}
這裏是我的ShowToast
public void ShowToast (String Msg) {
Context context = getApplicationContext();
CharSequence text = Msg;
int duration = Toast.LENGTH_LONG;
Toast toast = Toast.makeText(context, text, duration);
toast.setGravity(Gravity.CENTER|Gravity.CENTER, 0, 0);
toast.show();
}
，這裏是佈局

的衝突，哪裏是你的'ShowToast（）'函數？ – 2013-03-25 13:38:53
它如何「不起作用」？你有什麼嘗試？你看到錯誤還是敬酒不顯示？你的ShowToast方法是什麼樣的？你有沒有試過打印日誌語句？如果將toast/log和resetTimeout調用移動到onTextChanged會發生什麼？ – Sababado 2013-03-25 13:40:13
我添加了ShowToast – 2013-03-25 13:50:50
