在onCreate方法中TextWatcher的实现不起作用,我尝试使用虚拟键盘和硬件键盘进行文本输入,也尝试了模拟器和真实设备上的代码。似乎没什么用。
我甚至在布局中重命名了EditTexts并清理了项目,重新构建它,没有希望
任何想法?
这是代码
@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();
}
});
}
这是我的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();
}
这是布局
