在Android實作HTML TextView與AutoLink使用的建議方式

Android的TextView除了可以用來顯示文字資料之外，還可以使用HTML語法來調整文字的樣式和文字超連結，無需特地去使用WebView。只是一旦使用TextView製作超連結，該TextView就會變得難以控制，因此有幾個特性應該是設計師必須事先知道的。 TextView顯示HTML 要使用TextView顯示HTML的作法很簡單，只要用以下方式來setText即可。 ``` textView.setText(Html.fromHtml("HTML語法字串")); ``` 例如： ``` textView.setText(Html.fromHtml("歡迎大家來到<big><font color=\"#FF0000\"><b>MagicLen</b></font></big>，本站網址如下：<br/><br/><a href=\"http://magiclen.org/\">http://magiclen.org/</a>")); ``` 結果如下： ...

Android开发实践：自定义带消息循环（Looper）的工作线程

Android也提供了封装有消息循环（Looper）的HandlerThread类，这种线程，可以绑定Handler()对象，并通过 Handler的sendMessage()函数向线程发送消息，通过handleMessage()函数，处理线程接收到的消息。这么说比较抽象，那么，本文就利用基础的Java类库，实现一个带消息循环（Looper）的线程，以帮助初学者理解这样一个Looper到底是怎么工作的。 1. 首先，我们完成一个简单的线程框架。 1 <div class="line number2 index1 alt1"> 2 </div> <div class="line number3 index2 alt2"> 3 </div> <div class="line number4 index3 alt1"> 4 </div> <div class="line number5 index4 alt2"> 5 </div> <div class="line number6 index5 alt1"> 6 </div> <div class="line number7 index6 alt2"> 7 </div> <div class="line number8 index7 alt1"> 8 </div> <div class="line number9 index8 alt2"> 9 </div> <div class="line number10 index9 alt1"> 10 </div> <div class="line number11 index10 alt2"> 11 </div> <div class="line number12 index11 alt1"> 12 </div> <div class="line number13 index12 alt2"> 13 </div> <div class="line number14 index13 alt1"> 14 </div> <div class="line number15 index14 alt2"> 15 </div> <div class="line number16 index15 alt1"> 16 </div> <div class="line number17 index16 alt2"> 17 </div> <div class="line number18 index17 alt1"> 18 </div> <div class="line number19 index18 alt2"> 19 </div> <div class="line number20 index19 alt1"> 20 </div> <div class="line number21 index20 alt2"> 21 </div> <div class="line number22 index21 alt1"> 22 </div> <div class="line number23 index22 alt2"> 23 </div> <div class="line number24 index23 alt1"> 24 </div> <div class="line number25 index24 alt2"> 25 </div> <div class="line number26 index25 alt1"> 26 </div> <div class="line number27 index26 alt2"> 27 </div> <div class="line number28 index27 alt1"> 28 </div> <div class="line number29 index28 alt2"> 29 </div> <div class="line number30 index29 alt1"> 30 </div> <div class="line number31 index30 alt2"> 31 </div> <div class="line number32 index31 alt1"> 32 </div> <div class="line number33 index32 alt2"> 33 </div> </td> <td class="code"> <div class="container"> <div class="line number1 index0 alt2"> `public` `class` `LooperThread {` </div> <div class="line number2 index1 alt1"> ` ` </div> <div class="line number3 index2 alt2"> ` ``private` `volatile` `boolean` `mIsLooperQuit = ``false``;` </div> <div class="line number4 index3 alt1"> ` ` </div> <div class="line number5 index4 alt2"> ` ``private` `Thread mThread; ` </div> <div class="line number6 index5 alt1"> ` ` </div> <div class="line number7 index6 alt2"> ` ``public` `void` `start() { ` </div> <div class="line number8 index7 alt1"> ` ``if``( mThread != ``null` `) {` </div> <div class="line number9 index8 alt2"> ` ``return``;` </div> <div class="line number10 index9 alt1"> ` ``} ` </div> <div class="line number11 index10 alt2"> ` ``mIsLooperQuit = ``false``;` </div> <div class="line number12 index11 alt1"> ` ``mThread = ``new` `Thread(mLooperRunnable);` </div> <div class="line number13 index12 alt2"> ` ``mThread.start(); ` </div> <div class="line number14 index13 alt1"> ` ``}` </div> <div class="line number15 index14 alt2"> ` ` </div> <div class="line number16 index15 alt1"> ` ``public` `void` `stop() { ` </div> <div class="line number17 index16 alt2"> ` ``if``( mThread == ``null` `) {` </div> <div class="line number18 index17 alt1"> ` ``return``;` </div> <div class="line number19 index18 alt2"> ` ``} ` </div> <div class="line number20 index19 alt1"> ` ``mIsLooperQuit = ``true``;` </div> <div class="line number21 index20 alt2"> ` ``mThread = ``null``; ` </div> <div class="line number22 index21 alt1"> ` ``}` </div> <div class="line number23 index22 alt2"> </div> <div class="line number24 index23 alt1"> ` ``protected` `Runnable mLooperRunnable = ``new` `Runnable() { ` </div> <div class="line number25 index24 alt2"> </div> <div class="line number26 index25 alt1"> ` ``@Override` </div> <div class="line number27 index26 alt2"> ` ``public` `void` `run() {` </div> <div class="line number28 index27 alt1"> ` ``while``( !mIsLooperQuit ) {` </div> <div class="line number29 index28 alt2"> ` ` </div> <div class="line number30 index29 alt1"> ` ``}` </div> <div class="line number31 index30 alt2"> ` ``}` </div> <div class="line number32 index31 alt1"> ` ``}; ` </div> <div class="line number33 index32 alt2"> `}` </div> </div> </td> </tr> </table> ...

Android开发实践：自定义带动画的View

对于一个自定义View来说，onMeasure只是用来计算View尺寸，onDraw()才是真正执行View的绘制，所以一般我们都需要重写 onDraw()函数来绘制我们期望的UI界面。下面我以一个具体的例子探索自定义View的onDraw()的实现过程和关键点。我们的目标是制作一个柱状图动画，View的动画启动后，会显示一排柱状图增长的画面，这种动画多用于财务类或者统计类的APP中，效果如图所示（截屏的格式转换过程导致有些变形，还好不影响演示，图中设置了反复播放，真机上只会播放一次）： 1. 首先，自定义View的派生类 ** ** 1 <div class="line number2 index1 alt1"> 2 </div> <div class="line number3 index2 alt2"> 3 </div> <div class="line number4 index3 alt1"> 4 </div> <div class="line number5 index4 alt2"> 5 </div> <div class="line number6 index5 alt1"> 6 </div> <div class="line number7 index6 alt2"> 7 </div> <div class="line number8 index7 alt1"> 8 </div> <div class="line number9 index8 alt2"> 9 </div> <div class="line number10 index9 alt1"> 10 </div> <div class="line number11 index10 alt2"> 11 </div> <div class="line number12 index11 alt1"> 12 </div> <div class="line number13 index12 alt2"> 13 </div> <div class="line number14 index13 alt1"> 14 </div> <div class="line number15 index14 alt2"> 15 </div> <div class="line number16 index15 alt1"> 16 </div> <div class="line number17 index16 alt2"> 17 </div> <div class="line number18 index17 alt1"> 18 </div> <div class="line number19 index18 alt2"> 19 </div> <div class="line number20 index19 alt1"> 20 </div> <div class="line number21 index20 alt2"> 21 </div> <div class="line number22 index21 alt1"> 22 </div> <div class="line number23 index22 alt2"> 23 </div> <div class="line number24 index23 alt1"> 24 </div> <div class="line number25 index24 alt2"> 25 </div> </td> <td class="code"> <div class="container"> <div class="line number1 index0 alt2"> `public` `class` `AnimatorView ``extends` `View {` </div> <div class="line number2 index1 alt1"> </div> <div class="line number3 index2 alt2"> ` ``private` `Paint mPaint; ` </div> <div class="line number4 index3 alt1"> ` ` </div> <div class="line number5 index4 alt2"> ` ``public` `AnimatorView(Context context) {` </div> <div class="line number6 index5 alt1"> ` ``super``(context); ` </div> <div class="line number7 index6 alt2"> ` ``initialize();` </div> <div class="line number8 index7 alt1"> ` ``}` </div> <div class="line number9 index8 alt2"> </div> <div class="line number10 index9 alt1"> ` ``public` `AnimatorView(Context context, AttributeSet attrs) {` </div> <div class="line number11 index10 alt2"> ` ``super``(context, attrs);` </div> <div class="line number12 index11 alt1"> ` ``initialize();` </div> <div class="line number13 index12 alt2"> ` ``}` </div> <div class="line number14 index13 alt1"> ` ` </div> <div class="line number15 index14 alt2"> ` ``public` `AnimatorView(Context context, AttributeSet attrs, ``int` `defStyle) {` </div> <div class="line number16 index15 alt1"> ` ``super``(context, attrs, defStyle);` </div> <div class="line number17 index16 alt2"> ` ``initialize();` </div> <div class="line number18 index17 alt1"> ` ``}` </div> <div class="line number19 index18 alt2"> ` ` </div> <div class="line number20 index19 alt1"> ` ``protected` `void` `initialize() {` </div> <div class="line number21 index20 alt2"> ` ``mPaint = ``new` `Paint(); ` </div> <div class="line number22 index21 alt1"> ` ``mPaint.setAntiAlias(``true``);` </div> <div class="line number23 index22 alt2"> ` ``mPaint.setStyle(Style.FILL); ` </div> <div class="line number24 index23 alt1"> ` ``} ` </div> <div class="line number25 index24 alt2"> `}` </div> </div> </td> </tr> </table> 注： Paint是用来绘图的画笔，可以设置其样式、画面的粗细、填充模式、颜色等等。 ...

Android开发实践：为什么要继承onMeasure()

Android开发中偶尔会用到自定义View，一般情况下，自定义View都需要继承View类的onMeasure方法，那么，为什么要继承 onMeasure()函数呢？什么情况下要继承onMeasure()？系统默认的onMeasure()函数行为是怎样的？本文就探究探究这些问题。首先，我们写一个自定义View，直接调用系统默认的onMeasure函数，看看会是怎样的现象： 1 <div class="line number2 index1 alt1"> 2 </div> <div class="line number3 index2 alt2"> 3 </div> <div class="line number4 index3 alt1"> 4 </div> <div class="line number5 index4 alt2"> 5 </div> <div class="line number6 index5 alt1"> 6 </div> <div class="line number7 index6 alt2"> 7 </div> <div class="line number8 index7 alt1"> 8 </div> <div class="line number9 index8 alt2"> 9 </div> <div class="line number10 index9 alt1"> 10 </div> <div class="line number11 index10 alt2"> 11 </div> <div class="line number12 index11 alt1"> 12 </div> <div class="line number13 index12 alt2"> 13 </div> <div class="line number14 index13 alt1"> 14 </div> <div class="line number15 index14 alt2"> 15 </div> <div class="line number16 index15 alt1"> 16 </div> <div class="line number17 index16 alt2"> 17 </div> <div class="line number18 index17 alt1"> 18 </div> <div class="line number19 index18 alt2"> 19 </div> <div class="line number20 index19 alt1"> 20 </div> <div class="line number21 index20 alt2"> 21 </div> <div class="line number22 index21 alt1"> 22 </div> </td> <td class="code"> <div class="container"> <div class="line number1 index0 alt2"> `package` `com.titcktick.customview;` </div> <div class="line number2 index1 alt1"> </div> <div class="line number3 index2 alt2"> `import` `android.content.Context;` </div> <div class="line number4 index3 alt1"> `import` `android.util.AttributeSet;` </div> <div class="line number5 index4 alt2"> `import` `android.view.View;` </div> <div class="line number6 index5 alt1"> </div> <div class="line number7 index6 alt2"> `public` `class` `CustomView ``extends` `View {` </div> <div class="line number8 index7 alt1"> ` ` </div> <div class="line number9 index8 alt2"> ` ``public` `CustomView(Context context) {` </div> <div class="line number10 index9 alt1"> ` ``super``(context); ` </div> <div class="line number11 index10 alt2"> ` ``}` </div> <div class="line number12 index11 alt1"> </div> <div class="line number13 index12 alt2"> ` ``public` `CustomView(Context context, AttributeSet attrs) {` </div> <div class="line number14 index13 alt1"> ` ``super``(context, attrs); ` </div> <div class="line number15 index14 alt2"> ` ``}` </div> <div class="line number16 index15 alt1"> ` ` </div> <div class="line number17 index16 alt2"> ` ``@Override` </div> <div class="line number18 index17 alt1"> ` ``protected` `void` `onMeasure(``int` `widthMeasureSpec, ``int` `heightMeasureSpec) { ` </div> <div class="line number19 index18 alt2"> ` ``super``.onMeasure(widthMeasureSpec, heightMeasureSpec);` </div> <div class="line number20 index19 alt1"> ` ``}` </div> <div class="line number21 index20 alt2"> </div> <div class="line number22 index21 alt1"> `}` </div> </div> </td> </tr> </table> ...
