phone 数字查询后 EditText 为空 - Android
EditText empty after phone number query - Android
我在一个名为 addContact() 的对话框中有一个按钮，单击该按钮后，它应该在我的 Android phone 中打开我的 Contacts，它确实如此，并且然后当我点击一个联系人时，它应该从该联系人中提取 phone 号码并将其放入我的对话框中的 EditText 中，但这不起作用，它显示空白 EditText 场地。由于 EditText 在片段 xml 中（不在我的 activity xml 中），我必须使用 LayoutInflator 并将其放入 View 之前实例化我的 EditText，所以我想知道这是否与我的错误有关。问题是，我没有收到任何崩溃或错误代码，只有在单击联系人后出现空白的 EditText。我已经用另一种方法膨胀了对话框视图（见下文），但它在一个方法内部，所以我担心范围，所以当我需要它时我在 onActivityResult() 中再次膨胀它。那是对的吗？如何显示 phone 号码？谢谢。

so I inflated it again when I needed it inside the onActivityResult().
Is that correct?
否因为您膨胀了当前未添加到 AlertDialog 中的新布局视图，向用户显示。
使用与您在 onActivityResult() 中的肯定按钮点击相同的实例 etPhoneNumber 向用户显示数字：
finally {
if (cursor != null){
cursor.close();
}
if(dialog.isShowing())
etPhoneNumber.setText(phone);
if (phone.length() == 0) {
Toast.makeText(this, "No phone number found for contact.",
Toast.LENGTH_LONG).show();
}
}
还在 AlertDialog builder.setView 之后移动 etPhoneNumber 和 etMessage 的初始化，因为目前您正在点击“发送”按钮时初始化两者。
我在一个名为 addContact() 的对话框中有一个按钮，单击该按钮后，它应该在我的 Android phone 中打开我的 Contacts，它确实如此，并且然后当我点击一个联系人时，它应该从该联系人中提取 phone 号码并将其放入我的对话框中的 EditText 中，但这不起作用，它显示空白 EditText 场地。由于 EditText 在片段 xml 中（不在我的 activity xml 中），我必须使用 LayoutInflator 并将其放入 View 之前实例化我的 EditText，所以我想知道这是否与我的错误有关。问题是，我没有收到任何崩溃或错误代码，只有在单击联系人后出现空白的 EditText。我已经用另一种方法膨胀了对话框视图（见下文），但它在一个方法内部，所以我担心范围，所以当我需要它时我在 onActivityResult() 中再次膨胀它。那是对的吗？如何显示 phone 号码？谢谢。

so I inflated it again when I needed it inside the onActivityResult(). Is that correct?
否因为您膨胀了当前未添加到 AlertDialog 中的新布局视图，向用户显示。
使用与您在 onActivityResult() 中的肯定按钮点击相同的实例 etPhoneNumber 向用户显示数字：
finally {
if (cursor != null){
cursor.close();
}
if(dialog.isShowing())
etPhoneNumber.setText(phone);
if (phone.length() == 0) {
Toast.makeText(this, "No phone number found for contact.",
Toast.LENGTH_LONG).show();
}
}
还在 AlertDialog builder.setView 之后移动 etPhoneNumber 和 etMessage 的初始化，因为目前您正在点击“发送”按钮时初始化两者。
