Question

有两个EditText，如果用户在第一个字符中输入四个字符，焦点会自动转到另一个EditText。当用户在第二个EditText中输入第一个字符时，滚动中断并且第二个edittext开始留在键盘后面。

此外，当用户专注于第二个EditText时，它仍然会停留在键盘后面。如果用户首先对焦于第一个EditText然后关闭键盘并对焦第二个EditText，则滚动效果很好。

只有三星Galaxy Grand Prime（Android 4.4.4版本）才会出现此问题。

你能帮助解决这种奇怪的行为吗？

MyActivity.java

@Override
protected void onCreate(Bundle savedInstanceState) {
    //.....

    txtNewPin.setFocusable(true);
    txtNewPin2.setFocusable(true);
    txtNewPin.requestFocus();

    InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
    imm.toggleSoftInput(InputMethodManager.SHOW_FORCED, 0);

    txtNewPin.addTextChangedListener(getTextChangedListener_txtNewPin());
    txtNewPin2.addTextChangedListener(getTextChangedListener_txtNewPin2());

    //.....
}

private TextWatcher getTextChangedListener_txtNewPin() {
    return new TextWatcher() {
        @Override
        public void beforeTextChanged(CharSequence s, int start, int before, int count) {

        }

        @Override
        public void onTextChanged(CharSequence s, int start, int before, int count) {
            if (s.length() == 4) {
                txtNewPin.clearFocus();
                txtNewPin2.requestFocus();
            }
        }

        @Override
        public void afterTextChanged(Editable editable) {

        }
    };
}

private TextWatcher getTextChangedListener_txtNewPin2() {
    return new TextWatcher() {
        @Override
        public void beforeTextChanged(CharSequence s, int start, int before, int count) {

        }

        @Override
        public void onTextChanged(CharSequence s, int start, int before, int count) {
            if (s.length() == 4) {
                kart_sifre_degistir_button.performClick();
            }
        }

        @Override
        public void afterTextChanged(Editable editable) {

        }
    };
}

MyActivity xml

第一个EditText id：yeni_sifre_bir
第二个EditText id：yeni_sifre_iki
第三个EditText id：textview_editText_search（这个完美无缺!! ）

我意识到问题是由于在第二个EditText中输入一个字符后失去焦点。它突然失去了焦点！

Answer 1

尝试afterTextChanged

private TextWatcher getTextChangedListener_txtNewPin() {
return new TextWatcher() {
    @Override
    public void beforeTextChanged(CharSequence s, int start, int before, int count) {

    }

    @Override
    public void onTextChanged(CharSequence s, int start, int before, int count) {

    }

    @Override
    public void afterTextChanged(Editable editable) {
       if (editable.length() == 4) {
            txtNewPin.clearFocus();
            txtNewPin2.requestFocus();
        }
    }
};

}

解决。我已经更改了布局 MyActivity.xml ，如下所示（使用ScrollView和RelativeLayout而不是LinearLayout）

<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent">

        <RelativeLayout
            android:id="@+id/creditCardBackground"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            .... >

            ....

        </RelativeLayout>

        <RelativeLayout
