尝试专注于编辑文本时出现问题



实际上,我正在尝试为带或不带物理键盘的设备制作一个应用程序。

我在第一次编辑文本中添加了一个setOnEditorActionListener,当在物理键盘上按下actionDone或按下Enter按钮时,它应该使其他编辑文本可见并专注于它,但它不会聚焦于它。

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,我尝试关注的编辑文本是barcodeTxt,我试图聚焦的编辑文本是qtaTxt

您似乎请求将焦点集中在qta引用而不是EditText元素上。所以也许首先尝试做qtaText.requestFocus().

如果这不能解决它,则您的 XML 配置可能有问题。虽然不是该主题的专家,但我在最新的项目中确实有一个可聚焦的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。
