Transferred from: http://blog.csdn.net/lizzy115/article/details/7513552FloatOther than that:1) QuestionsWhen you implement an adaptive Tablectrl control in Android to display text information, there is a problem when you need to get the width value of the longest string in a column. After searching the internet, I discovered that Android can take advantage of the Measuretext (Stringtext) method of the paint already provided in the SDK. So try the code that has been given online:Paint paint = new

);canvas.drawCircle(bounds.centerX(), bounds.centerY(), outerRadius - outLineWidth, mPaint);The center is the center of the drawing area, and the radius is the width of the 绘制区域圆 radius minus 外部轮廓圆线 . This just fills the circles and the outer contour circles do not overlap.Draw an outer border circleThis is simple because it is a hollow line, so Style Yes STROKE , then set the width of the line, the color of the brush:2, mPaint);The center of the Circle is the center of the drawing area, and the

Objective Before writing an article on the effect of TextView, then the actual project has found new problems, such as still can not run automatically, text over the display area on the interception of the problem, today changed a way of thinking to achieve, simpler and better use. Body Code implementation: public class Marqueetextview extends TextView {/** Stop scrolling */private Boolean mstopmarquee; Private String Mtext; private float Mcoordinatex; private float mtextwidth;

it with the Getdrawable method. The method used here and Baidu common to the method is slightly different, because Baidu on the method in my here will have a bug, in the second entry when the picture is often not loaded out.First, write a class that inherits Bitmapdrawable, with the following code:Package Com.githang.gradledoc.chapter;import Android.graphics.bitmap;import Android.graphics.canvas;import android.graphics.drawable.bitmapdrawable;/** * User:geek_soledad ([email protected]) * date:2

Listview selects the last item by default.Android: stackfrombottom = "true" Android: transcriptmode = "alwaysscroll"Android Chinese boldAndroid: FIG = "#000000"Android: shadowdx = "0.2" Android: shadowdy = "0.0" Android: shadowradius = "0.2"Android: textstyle = "bold" can be used in XML files to set English to bold, but Chinese cannot be set to bold,The method for setting Chinese characters to bold is textview TV = (textview) findviewbyid (R. Id. textview01 );Textpaint TP = TV.

, The conversion efficiency of Android dateformat classes is much higher than that of Java. Question 2: How to Reduce the layout layers of itemview in listview I have already written this article. As mentioned in my previous blog, although using the merge label as the top-level label can reduce the level of view, all the attributes set in the merge label will not work, you need to set it in the code. Question 3: Set the bold format for Chinese Characters Mpublisher = (Textview)

Because a new project requires a font and underline effect, the visual effect can be forged through images. However, in order to reflect the technical content, I want to use textview to underline the effect. There are two methods. The first one isMtxtregister. getpaint (). setflags (paint. underline_text_flag);The second type isMtxtregister. settext (html. fromhtml ("After comprehensive comparison, it is found that the first method is ineffective, and
