问题描述

在我的应用程序需要动态文本设置为我TextView的，所以我希望它得到动态调整大小。我已经设置：

In my application I need to set dynamic text to my textview so I want it to get resized dynamically. I have set:

<TextView
android:id="@+id/TextView02" 
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textStyle="normal"
android:text="Frontview"
android:layout_weight="1"
android:gravity="center_vertical"
android:textColor="#0099CC"
android:singleLine="false"
android:maxLines="4"
android:ellipsize="marquee"
/>

我的TextView的高度不超出2线和文字得到削减。 任何人都可以请帮助？

My textview height is not going beyond 2 lines and the text is getting cut. Can anybody please help?

感谢名单提前。

推荐答案

正如康斯坦丁说，这code可能会被你超过4行之后，除非你删除安卓忽略

As Konstantin said, this code will probably be ignored after you exceed 4 lines unless you remove android:maxLines="4"

这是你将如何设置code的高度：

This is how you would set the height in code:

TextView tv = (TextView) findViewById(R.id.TextView02);
int height_in_pixels = tv.getLineCount() * tv.getLineHeight(); //approx height text
tv.setHeight(height_in_pixels);

如果你想使用浸台，这使得你的应用程序扩展到多个屏幕尺寸，你会通过返回的值getResources（）乘以像素数getDisplayMetrics（）密度;

If you want to use dip units, which allows your app to scale across multiple screen sizes, you would multiply the pixel count by the value returned by getResources().getDisplayMetrics().density;

这取决于你想要的行为，但你也可以考虑具有TextView的尺寸固定，并允许用户滚动文本：

This depends on your desired behavior, but you might also consider having the TextView size fixed, and allowing the user to scroll the text:

TextView tv = (TextView)findViewById(R.id.TextView02);
tv.setMovementMethod(ScrollingMovementMethod.getInstance());
