如何在 Android 上获取多行警报标题

发布于 2024-12-09 01:15:35 字数 951 浏览 0 评论 0原文

有没有办法在 AlertDialog 中获取超过 2 行的警报标题？

我只发现“创建自定义对话框”作为可能的解决方案。

然而，理想情况下，人们可以只设置一个属性 - 但我找不到任何属性。

编辑：

AlertDialog alertDialog = new AlertDialog.Builder(AlertAndCallUtility.this).create();
alertDialog.setTitle(getString(R.string.alert_title));
alertDialog.setMessage(getString(R.string.alert_msg));
alertDialog.setButton(getString(R.string.alert_OK),
    new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int which) {
            finish();
        }});
alertDialog.setIcon(R.drawable.icon);
alertDialog.show();

和如上所述的 xml

<string name="alert_OK">OK:</string>
<string name="alert_title">Please correct your input, parameters are missing.</string>
<string name="alert_msg">Please enter them in the EXTRA tab.</string>

，在“..missing”之前插入 \n，只需将其切断，并且只能看到前两行，直到标题的“are”。

原文

Is there a way to get more than the 2 lines for the Alert title in an AlertDialog?

I only find "creating a custom dialog" as a possible solution.

Ideally however, one could just set an attribute - but I can't find any.

EDIT:

AlertDialog alertDialog = new AlertDialog.Builder(AlertAndCallUtility.this).create();
alertDialog.setTitle(getString(R.string.alert_title));
alertDialog.setMessage(getString(R.string.alert_msg));
alertDialog.setButton(getString(R.string.alert_OK),
    new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int which) {
            finish();
        }});
alertDialog.setIcon(R.drawable.icon);
alertDialog.show();

and xml

<string name="alert_OK">OK:</string>
<string name="alert_title">Please correct your input, parameters are missing.</string>
<string name="alert_msg">Please enter them in the EXTRA tab.</string>

as mentioned, inserting a \n right before "..missing", just cuts it off and one only sees the first two lines until "are" of the title.

您需要使用AlertDialog.Builder().setCustomTitle()：

AlertDialog.Builder dialogBuilder = new AlertDialog.Builder(context);
TextView textView = new TextView(context);
textView.setText("your very long title here");
dialogBuilder.setCustomTitle(textView);

You need to use AlertDialog.Builder().setCustomTitle():

AlertDialog.Builder dialogBuilder = new AlertDialog.Builder(context);
TextView textView = new TextView(context);
textView.setText("your very long title here");
dialogBuilder.setCustomTitle(textView);
