edit_en.addTextChangedListener(new TextWatcher() { @Override public void beforeTextChanged(CharSequence s, int start, int count, int after) { } @Override public void onTextChanged(CharSequence s, int start, int before, int count) {if (edit_en.isFocused()) { edit_zh.setHint('0'); edit_en.setHint('請輸入金額'); edit_zh.setText(dollar2RMB(s.toString())+''); Log.d('aa', 'edit_en::' + s.toString());} } @Override public void afterTextChanged(Editable s) { }});edit_zh.addTextChangedListener(new TextWatcher() { @Override public void beforeTextChanged(CharSequence s, int start, int count, int after) { } @Override public void onTextChanged(CharSequence s, int start, int before, int count) {if (edit_zh.isFocused()) { edit_zh.setHint('請輸入金額'); edit_en.setHint('0'); edit_en.setText(rmb2Dollar(s.toString()) + ''); Log.d('aa', 'edit_zh::' + s.toString());} } @Override public void afterTextChanged(Editable s) { }});
