本文实例总结了Android编程经典代码段。分享给大家供大家参考,具体如下:

1、 复制,粘贴

clip = (ClipboardManager)getSystemService(Context.CLIPBOARD_SERVICE);clip.setText("copy"); // 复制clip.getText(); // 粘贴

2、调用浏览器

核心代码如下:

Intent intent = new Intent();intent.setAction("android.intent.action.VIEW");Uri content_url = Uri.parse("//www.VeVB.COm");intent.setData(content_url);//调用指定浏览器―UCintent.setClassName("com.uc.browser", "com.uc.browser.ActivityUpdate");startActivity(intent);

具体步骤与实现代码可参考前面一篇《Android开发之浏览器用法实例详解

3、根据包名,去软件市场查找

Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse("market://search?q=pname:com.acp.main"));startActivity(intent);

4、Toast一直显示

final Toast toast = Toast.makeText(context,"toast", Toast.LENGTH_LONG);Timer timer = new Timer();timer.schedule(new TimerTask() {  @Override  public void run() {    // TODO Auto-generated methodstub    while (flag) {      toast.show();    }  }}, 10);

5、自定义Dialog

final Dialog mInfoDlg = new Dialog(context,R.style.dialog);// R.style.dialog  去掉dialog的最上面title部分LayoutInflater factory = LayoutInflater.from(context);View nCurrView = factory.inflate(R.layout.mydialog, null);nCurrView.setBackgroundResource(R.drawable.bgline);LinearLayout nParentLayout = (LinearLayout)nCurrView.findViewById(R.id.iparents);nParentLayout.setBackgroundResource(R.drawable.titlebgline);mInfoDlg.setContentView(nCurrView);Button nBt1 = (Button)nCurrView.findViewById(R.id.button1);nBt1.setText("返回");nBt1.setTypeface(Typeface.create(Typeface.SERIF, Typeface.BOLD));nBt1.setOnClickListener(new Button.OnClickListener() {  @Override  public void onClick(View v) {    // TODO Auto-generated methodstub    mInfoDlg.dismiss();  }});mInfoDlg.show();

R.style.dialog:

<?xml version="1.0"encoding="utf-8"?><resources>  <style name="dialog"parent="@android:style/Theme.Dialog">    <itemname="android:windowNoTitle">true</item>  </style></resources>

R.drawable.titlebgline:

<?xml version="1.0"encoding="utf-8"?><shapexmlns:android="http://schemas.android.com/apk/res/android">  <gradientandroid:startColor="#ff9911" android:endColor="#FF9911"/>  <strokeandroid:width="1dp" android:color="@color/inputTxt" />  <cornersandroid:radius="5dp" /></shape>

希望本文所述对大家Android程序设计有所帮助。
