我有一个AlertDialog，它有一个EditText。此EditText接受用户输入并在＆＃34; Post＆＃34;按钮单击API调用已启动。
问题是AlertDialog应该在＆＃34; Post＆＃34;单击按钮。目前我必须点击外面的区域来解雇它。
如果我删除API调用，则AlertDialog会在按钮单击时正确解除。
我不确定是什么问题。
这是我的代码： -
case R.id.btnAddComms:
scrollNews.fullScroll(v.FOCUS_DOWN);
btnAddComms.setPressed(true);
AlertDialog.Builder builder = new AlertDialog.Builder(NDetails.this);
builder.setTitle("Post Comment");
builder.setIcon(R.drawable.post_comment_button);
final EditText input1 = new EditText(NDetails.this);
LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(
LinearLayout.LayoutParams.MATCH_PARENT,
LinearLayout.LayoutParams.MATCH_PARENT);
input1.setLayoutParams(lp);
builder.setView(input1);
builder.setPositiveButton("Post", new DialogInterface.OnClickListener()
{
//private ITextInputDialogCalback callback;
public void onClick(DialogInterface dialog, int id)
{
postedComment = input1.getText().toString();
if(postedComment.length()>0)
{
dialog.cancel();
PostComments(postedComment);
}
else
{
Toast.makeText(NewsDetails.this, "Please enter a comment.", Toast.LENGTH_LONG).show();
input1.findFocus();
}
}
private void PostComments(String postedComment)
{
// TODO Auto-generated method stub
String postCommentUrl = url;
try
{
String commentResponse = new PostComment().execute(postCommentUrl).get();
String getRequestForComments = myurl;
String items = new FetchItems().execute(getRequestForComments).get();
ArrayList<HashMap<String, String>> updatedCommentList = new GetList().execute(items).get();
itemsAdapter = (ListAdapter) new CommentsAdapter(NDetails.this, updatedCommentList);
commentsList.invalidate();
commentsList.refreshDrawableState();
commentsList.setAdapter(itemsAdapter);
commentsList.post(new Runnable()
{
@Override
public void run()
{
// TODO Auto-generated method stub
commentsList.setSelection(itemsAdapter.getCount()-1);
}
});
}
catch (InterruptedException e)
{
// TODO Auto-generated catch block
e.printStackTrace();
}
catch (ExecutionException e)
{
// TODO Auto-generated catch block
e.printStackTrace();
}
}
})
.setCancelable(false);
AlertDialog alert = builder.create();
alert.setCanceledOnTouchOutside(true);
alert.show();
break;

alert.show();
break;
使用

break;

做下一个：
AlertDialog alert; // Define it in your activity or fragment
...
case R.id.btnAddComms:
...
builder.setPositiveButton("Post", new DialogInterface.OnClickListener()
{
//private ITextInputDialogCalback callback;
public void onClick(DialogInterface dialog, int id)
{
postedComment = input1.getText().toString();
if(postedComment.length()>0)
{
alert.dismiss(); // Dismiss dialog here
PostComments(postedComment);
}
else
{
Toast.makeText(NewsDetails.this, "Please enter a comment.", Toast.LENGTH_LONG).show();
input1.findFocus();
}
...
alert = builder.create();
alert.setCanceledOnTouchOutside(true);
alert.show();
break;

只需更换对话框＆＃34; post＆＃34;按钮点击代码到下面的代码：
<强>更新：
AlertDialog.Builder builder = new AlertDialog.Builder(context);
builder.setMessage("your message");
builder.setPositiveButton("Post", new DialogInterface.OnClickListener()
{
@Override
public void onClick(DialogInterface dialog, int which)
{
postedComment = input1.getText().toString();
if(postedComment.length()>0)
{
PostComments(postedComment);
dialog.dismiss();
}
else
{
Toast.makeText(NewsDetails.this, "Please enter a comment.", Toast.LENGTH_LONG).show();
input1.findFocus();
}
}
});
builder.setNegativeButton("Cancel", new DialogInterface.OnClickListener()
{
@Override
public void onClick(DialogInterface dialog, int which)
{
dialog.dismiss();
}
});
builder.show();

尝试以不同的方式创建对话框。可以使用这样的东西：
new AlertDialog.Builder(ACT_NewsListings.this)
.setTitle("Title")
.setMessage("Message")
.setCancelable(false)
.setPositiveButton("Post", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which)
{
dialog.dismiss();
//YOUR STUFF HERE
}
})
.show();
