Question

android中当编辑框中输入一个数字后如何让另外一个文本框马上显示东西

Answer 1

加入Edit.addTextChangedListener(Listener),监听里有文字变化时可以做相应的处理.

追问

能告诉我具体怎么实现吗，主要加在什么地方

追答

EditText A;
EditText B;
A.addTextChangeListener(new TextWatcher(){
@Override
publicvoid onTextChanged(xxxx){
B.setText(xxxx);
}
...
});
写了个大概的样子.

追问

谢谢，现在搞定了

Answer 2

//实时监听EditText内容变化
editText.addTextChangedListener(new TextWatcher() {

@Override
public void onTextChanged(CharSequence arg0, int arg1, int arg2, int arg3) {
// TODO Auto-generated method stub

}

@Override
public void beforeTextChanged(CharSequence arg0, int arg1, int arg2,
int arg3) {
// TODO Auto-generated method stub

}

@Override
public void afterTextChanged(Editable arg0) {
// TODO Auto-generated method stub
//改变TextView内容

textView.setText(arg0.toString());
}
});
