Android-帮助使用EditText修复“自定义警报"对话框 [英] Android- Help fixing Custom Alert Dialog with EditText
问题描述
上下文:有一个自定义的Listview，每个列表项中都有一个按钮.当您单击按钮时，将显示一个带有编辑文本和提交按钮的alertDialog.这仅在第一次单击时发生，在随后的单击中，Toast将仅显示其到目前为止被单击的次数.
Context: There is a custom Listview and each list item has a button in it. When you click the button an alertDialog appears with an edit text and submit button. This only happens on the first click, on subsequent clicks a Toast will simply appear with the number of times it has been clicked thus far.
当您单击提交按钮时，将出现一个祝酒词，显示输入到editText中的文本以及他们单击它的次数，该次数通常为1，因为只有在第一次单击时才会发生这种情况.
When you click the submit button a toast will appear displaying the text that was entered into the editText and the number of times they have clicked on it which will presumably always be 1 since this can only happen on the first click.
问题:如果用户在单击提交"之前点击了"editText"，那么timesClicked计数器无法正常工作.我猜是0.但是，如果用户 not 单击editText，则程序将正常运行. 0_o我很茫然.
Problem: The timesClicked counter is not working properly if the user so much as clicks on the editText before clicking submit. It is restting to 0 I guess. However if the user does not click on the editText then the program works normally. 0_o I'm at a loss.
尝试解决的问题:我将代码简化了很多，以尝试找出问题所在，这就是我遇到的问题.最初，我只是夸大一个只有编辑文本的视图，然后才使用builder.setPositiveButtton.我认为直接在视图中实现按钮将解决此问题，但事实并非如此.我已经坚持了一段时间.任何帮助都很好
Attempts at solving: I simplified the code down quite a bit to try and pinpoint the problem and this is where I am stuck. Originally I was inflating a view that only had an edit text and then I was just using builder.setPositiveButtton. I thought implementing the buttons directly in the view would fix it but that doesn't seem to be the case. I have been stuck on this for awhile. Any help would be great
private class OnSubtractClickListener implements View.OnClickListener {
final int id; //id of list item that was clicked
int timesClicked;
Toast toast;
public OnSubtractClickListener(int id, View view) {
super();
this.id = id;
timesClicked = 0;
}
@Override
public void onClick(View view) {
if (timesClicked != 0) {
toast.setText(Integer.toString(timesClicked));
toast.show();
}
else{
toast = Toast.makeText(view.getContext(), "", Toast.LENGTH_SHORT);
final View dialogView = LayoutInflater.from(view.getContext()).inflate(R.layout.dialog_add_notes, null);
AlertDialog.Builder builder = new AlertDialog.Builder(view.getContext());
builder.setView(dialogView);
builder.setTitle("Subtract cigar?");
builder.setIcon(R.mipmap.monkey_launcher);
final AlertDialog dialog = builder.create();
Button yesButton = (Button)dialogView.findViewById(R.id.dialog_notes_yes_button);
yesButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
EditText editText = (EditText)dialogView.findViewById(R.id.dialog_editText);
String userInput = editText.getText().toString();
String timesClickedString = Integer.toString(++timesClicked);
toast.setText(timesClickedString + ": " + userInput);
toast.show();
dialog.dismiss();
}
});
dialog.show(); //new
}
}
}
推荐答案
我找到了解决方案.基本上发生的事情是，当键盘出现时，它将导致列表视图调整大小，从而使用对话框出现之前的列表项的回收/旧版本重新创建整个列表视图-有效地撤消了对话框对列表视图项所做的任何更改
I found the solution. Basically what was happening was that when the Keyboard appeared it would cause the listview to adjust the size recreating the whole listview with recycled/old versions of the list items from before the dialog appeared -effectively undoing any changes made to the ListView items by the dialog.
在您的列表视图XML中添加以下内容:
In your listview XML add this:
android:descendantFocusability ="beforeDescendants"
android:descendantFocusability="beforeDescendants"
在Mainfest.xml中:
In Mainfest.xml:
<activity android:name= ".yourActivity"
android:windowSoftInputMode="adjustPan"/>
