尝试着重于EditText

Question

实际上，我正在尝试为带有或不带有物理键盘的设备制作应用程序。

我在我的第一个editText上添加了一个setOnEditorActionListener，当在物理键盘上按下actionDone或按下Enter键时，它应该使另一个editText可见并专注于它，但不会专注于它。

这是我的OnEditorActionListner方法：

  public void codeText(){
        code.setOnEditorActionListener(new TextView.OnEditorActionListener() {
            @Override
            public boolean onEditorAction(TextView textView, int i, KeyEvent keyEvent) {
                if(i == EditorInfo.IME_ACTION_DONE || keyEvent.getKeyCode() == KeyEvent.KEYCODE_ENTER){
                    if(!code.getText().toString().equals("")){
                        if (TextUtils.isDigitsOnly(code.getText())) {
                            if (code.getText().length() >= 1 && code.getText().length() <= 999999) {
                                qtaBox.setVisibility(View.VISIBLE);
                                qtaText.setVisibility(View.VISIBLE);
                                qta.requestFocus();
                            }
                        }
                    }
                }
                return true;
            }
        });
    }

完整的xml代码，我要聚焦的editText是barcodeTxt我要聚焦的edittext是qtaTxt

Answer 1

您似乎希望将焦点集中在qta引用而不是EditText元素上。因此，也许首先尝试做qtaText.requestFocus()。

如果这不能解决，则您的XML配置可能有问题。虽然不是该主题的专家，但我在最新项目中确实有一个重点突出的EditText元素，其中XML如下所示：

<EditText
    android:id="@+id/email"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:fontFamily="@font/opensans_light"
    android:hint="@string/prompt_email"
    android:inputType="textEmailAddress"
    android:keepScreenOn="true"
    android:maxLines="1"
    android:singleLine="true"
    android:textColor="@android:color/white" />

希望这可以帮助您解决问题。
