Question

在我的应用程序中，我有一个带有EditText的片段，该片段实现了textWatcher来设置遮罩...它在27（Oreo）之前的Android上运行良好，但是在Oreo上我注意到有时它无法正常工作...就像叫了两次

即使我只是removeTextChangedListener，settext和addTextChangedListener，有时也会重复一个字符。如果我删除一个字符，它也会发生。

示例：如果我在键盘上按击键，则在edittext randonly上将显示为或屁股

在日志屏幕上，我得到了：

以前有人遇到过这个问题吗？有人曾经遇到过这个问题吗？

Answer 1

这是我要在评论中说的一个小例子。

示例

if (etCPF == nul) {
    etCPF = (EditText) findViewById(R.id.editText)
    etCPF.addTextChangedListener(new 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) {
            etCPF.removeTextChangedListener(this);
            etCPF.setText(charSequence);
            etCPF.setSelection(etCPF.getText().length());
            etCPF.addTextChangedListener(this);
         }

         @Override
         public void afterTextChanged(Editable editable) { }
    });
}

这是为什么，因为我认为我们处于生命周期方法，而不是通过示例旋转Activity，然后您花了很多时间TextWatcher来重复这种方法。因此，这可以解释为什么他们很多TextWatcher

Android Oreo上的TextWatcher重复字符
