问题描述

我的edittext格式有以下代码，因为它可以接受任何输入我没有设置任何输入类型:

I have following code for my edittext formatting, since it can take any input I am not setting any input type:

if (cardNumberEditText != null) {
    cardNumberEditText.addTextChangedListener(new TextWatcher() {

        @Override
        public void onTextChanged(CharSequence s, int start, int before, int count) {
            int currSel = cardNumberEditText.getSelectionStart();
            cardNumberEditText.removeTextChangedListener(textWatcher);
            .
            .
            cardNumberEditText.setText(formattedNumber);
            .
            .
            cardNumberEditText.setSelection(currSel);
            cardNumberEditText.addTextChangedListener(textWatcher);
        }

        @Override
        public void beforeTextChanged(CharSequence s, int start, int count, int after) {
        }

        @Override
        public void afterTextChanged(Editable s) {

        }
    });
}

所以最初我得到的默认输入类型是 ABC，现在当我将其更改为 ?123(使用 ABC/123? 切换按钮)并输入一些数字后，键盘变回 ABC.此代码可以在三星设备 s3 和 sywpe 上正常工作，但不能在与 L 和 HTC one 的 nexus 上工作

So initially I get the default input type which is ABC, now when I change it to ?123 (using ABC/123? toggel button) and after entering some number the keyboard changes back to ABC. This code seams to work fine on samsung devices s3 and sywpe but not on nexus with L and HTC one

当我注释 onTextChanged 中的所有代码时，它工作正常.所以当我调查时发现罪魁祸首是 cardNumberEditText.setText(formattedNumber);

When I comment all the code inside onTextChanged, it works fine. So when I investigated I found out that culprit is cardNumberEditText.setText(formattedNumber);

我没有设置任何输入类型，我只是使用键盘上的 ABC/?123 切换键进行切换

I am not setting any input type, I am just using the ABC/?123 toggle key on keyboard for switching

任何帮助/建议为什么会发生这种情况(在少数设备上)，我该如何纠正它??

Any help/suggestion why this is happening (on few devices) and how can I correct it ??

推荐答案

终于搞定了，必须结合上面评论中提到的多个解决方案

finnaly got it working, had to combine multiple solutions mentioned in the comments above

因为有罪的是 settext，所以我找到了一个替代品 - 追加

since the guilty was settext, I found a replacement for it - append

但要使用附加，我必须在不使用 settext 的情况下清除 edittext，此链接 救援

but to use append I had to clear edittext without using settext, this link to the rescue

换了

cardNumberEditText.setText(formattedNumber);

与

cardNumberEditText.getText().clear();
cardNumberEditText.append(formattedNumber);

现在像魅力一样工作
