Android两个EditText互相监听

解决问题：两个EditText互相监听会造成死循环，导致app处于假死状态

1.添加标志位，标志是否被编辑

private boolean flag = true;

2.添加TextWatcher监听器

（1）第一个监听器
class TextWatcher1 implements TextWatcher {

@Override
public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) {
}

@Override
public void onTextChanged(CharSequence charSequence, int i, int i1, int i2) {
}

@Override
public void afterTextChanged(Editable editable) {
if (!TextUtils.isEmpty(editable.toString())) {
if (flag) {
flag = false;
mEt2.setText((Double.parseDouble(editable.toString()) / 10) + "");
} else {
flag = true;
}
}
}
}
（2）第二个监听器
class TextWatcher2 implements TextWatcher {

@Override
public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) {
}

@Override
public void onTextChanged(CharSequence charSequence, int i, int i1, int i2) {
}

@Override
public void afterTextChanged(Editable editable) {

if (!TextUtils.isEmpty(editable.toString())) {
if (flag) {
flag = false;
mEt1.setText((Double.parseDouble(editable.toString()) * 10) + "");
} else {
flag = true;
}
}
}
}

3.设置监听

TextWatcher1 textWatcher1 = new TextWatcher1();
TextWatcher2 textWatcher2 = new TextWatcher2();

mEt1.addTextChangedListener(textWatcher1);
mEt2.addTextChangedListener(textWatcher2);

总结：以上简单的三步就可以使两个EditText互相监听造成的死循环解决了
