更改字体大小到AlertDialog [英] Changing font size into an AlertDialog

问题描述

我试图把一些loooong文本到AlertDialog。 唯一的问题默认字体大小实在是太大了，所以我想使它更小。

I am trying to put some loooong text into an AlertDialog. The only issue the default font size that is really too big, so I want to make it smaller.

下面都是我试过的解决办法和他们的问题。

Here are all the workaround I tried and their issues.

解决方法1）使用一个TextView和myView.setTextSize（12）;

Workaround 1) Using a TextView and myView.setTextSize(12);

final TextView myView = new TextView(getApplicationContext());
myView.setText(myLongText);
myView.setTextSize(12);
final AlertDialog d = new AlertDialog.Builder(context)
    .setPositiveButton(android.R.string.ok, null)
.setTitle(myTitle)
.setView(myView)
.create();

的问题的：布局不滚动

解决方法2）制作的TextView滚动。

Workaround 2) making TextView scrollable.

message.setMovementMethod(LinkMovementMethod.getInstance());

的问题的：布局滚动，布特没有惯性（不知道怎么称呼的..但我猜你懂的）

Issues: Layout is scrolling, bute there is no "inertia" (don't know how to call that.. But I guess you understand.)

解决方法3）使用滚动型。

这就是我要试试，但我不能相信，有没有更简单的解决方案...

That's what I am going to try, but I cannot believe there are no easier solutions...

推荐答案

实际上，你可以访问该消息的TextView的pretty的轻松，然后改变它的大小。我用大一号的测试，但你可以使用任何你想要的大小。该文本将滚动很好，因为它已经这样做了。该视图的id是android.R.id.message：

You can actually get access to the message's TextView pretty easily, and then change it's size. I tested with a bigger size, but you could use whatever size you want. The text will scroll nicely as it already does. The view's id is android.R.id.message :

    AlertDialog dialog = new AlertDialog.Builder(this).setMessage("Hello world").show();
    TextView textView = (TextView) dialog.findViewById(android.R.id.message);
    textView.setTextSize(40);

这可能是一个更清洁的解决方案，但我不知道是否有一个风险，即TextView的可能是空或不是。

This is probably a cleaner solution, though I'm not sure if there's a risk that the TextView could be null or not.
