在AlertDialog.Builder中显示整个setTitle

Question

我试图在AlertDialog.Builder中显示setTile的整个句子，但我只是获得部分显示。我如何使用AlertDialog.Builder来管理？

AlertDialog.Builder builder = new AlertDialog.Builder(this); 

builder.setTitle("Please help us to track the route, has this route arrived the stop? "); 

我很感激任何帮助。

Answer 1

对于长文本（或你显示纯文本）使用setMessage：

builder.setMessage("Please help us to track the route, has this route arrived the stop? "); 

使用setTitle的一条消息很短的东西，爽快除了或者使用没有标题的。

至于什么@Eugene^h建议，你可以删除AlertDialog的称号，并使用自定义XML布局与一个TextView，将作为您的标题。

为此，您需要从对话框中删除Window.FEATURE_NO_TITLE。

final View dialogView = View.inflate(this, R.layout.custom_dialog, null); 
final AlertDialog alertDialog = new AlertDialog.Builder(this).create(); 
alertDialog.requestWindowFeature(Window.FEATURE_NO_TITLE); 

TextView tvTitle = (TextView)dialogView.findViewById(R.id.tvTitle); 
tvTitle.setText("Please help us to track the route, has this route arrived the stop?");
