我正在创建2个edittexts。当用户按下任何数字时，它会聚焦到下一个Edittext然后用户输入任何数字我将图像更改为edittext，它在三星中作为例外工作，但它在nexus和htc中不起作用，问题出在哪里？当我专注于请求时，调用edittext2 onkeylistener正在工作。这是代码问题吗？
edit_text_1.addTextChangedListener(new TextWatcher() {
@Override
public void onTextChanged(CharSequence s, int start, int before,
int count) {
// TODO Auto-generated method stub
System.out.println("count:" + count);
System.out.println("s: " + s.length());
if (count == 0) {
System.out.println("before1");
edit_text_1
.setBackgroundResource(R.drawable.single_dashuse);
} else {
System.out.println("before2");
System.out.println("ed1 value : " + edit_text_1.getText());
edit_text_1
.setBackgroundResource(R.drawable.singledashcircle);
String et1value = edit_text_1.getText().toString();
System.out.println("et1 value: " + et1value);
}
}
@Override
public void beforeTextChanged(CharSequence s, int start, int count,
int after) {
// TODO Auto-generated method stub
System.out.println("before");
}
@Override
public void afterTextChanged(Editable s) {

System.out.println("afterTextChanged in 1");

System.out.println("before3");
edit_text_1
.setBackgroundResource(R.drawable.singledashcircle);
