我想TextWatcher為多個EditText字段實現接口。目前我正在使用：text1.addTextChangedListener(this);text2.addTextChangedListener(this);然后覆蓋我的Activity中的方法：public void afterTextChanged(Editable s) {}public void beforeTextChanged(CharSequence s, int start, int count, int after) {}public void onTextChanged(CharSequence s, int start, int before, int count) { // do some operation on text of text1 field // do some operation on text of text2 field }但這工作正常，但我正在尋找其他方法，以便可以明確確定當前關注的EditText領域SoftKeyboard。

我會這樣：
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
EditText e = new EditText(this);
e.addTextChangedListener(new CustomTextWatcher(e));
}
private class CustomTextWatcher implements TextWatcher {
private EditText mEditText;
public CustomTextWatcher(EditText e) {
mEditText = e;
}
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
}
public void onTextChanged(CharSequence s, int start, int before, int count) {
}
public void afterTextChanged(Editable s) {
}
}
