android - Android EditText事件监听器

我正在为onTextChanged()和EditText事件处理程序使用onKey()。我想在输入文本时处理onTextChanged()，在删除文本时处理onKey()，即我想处理KEYCODE_DEL。但我的onTextchanged()事件总是触发。任何人都可以给我发一些想法。

ed.setOnKeyListener(this);
ed. addTextChangedListener(new TextWatcher() {
@Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
   //
});
@Override
public boolean onKey(View v, int keyCode, KeyEvent event) {
if (keyCode == KeyEvent.KEY CODE_ENTER) {
//
});

最佳答案

我通过在textWatcher（）中编写整个逻辑解决了这个问题，使用它的所有回调，因为onKeyListener不会为Nexus设备的软键盘触发。
我张贴的代码可能对其他人有帮助

    ed.addTextChangedListener(new TextWatcher() {
                private String previousDigits, num;
                private boolean textChanged = false;

                @Override
                public void onTextChanged(CharSequence currentDigits, int start,
                        int before, int count) {
                    if (!(previousDigits.equalsIgnoreCase(currentDigits.toString()))) {
                        textChanged = true;
                        num = getStrippedNumber(currentDigits
                                .toString());
                                            //getStrippedNumber method is used for getting the numeric digits from the string.
                        if (num.length() > 6) {
                            num = ("(" + num.substring(0, 3) + ") "
                                    + num.substring(3, 6) + "-" + num.substring(6));
                        } else if (num.length() > 3) {
                            num = ("(" + num.substring(0, 3) + ") " + num
                                    .substring(3));
                        }
                    }
                }

                @Override
                public void beforeTextChanged(CharSequence s, int start, int count,
                        int after) {
                    previousDigits = s.toString();
                }

                @Override
                public void afterTextChanged(Editable s) {
                    if (textChanged) {
                        textChanged = false;
                        mEditPhoneNo.setText(num);
                        mEditPhoneNo.setSelection(mEditPhoneNo.getText().length());
                    }
                }
            });
