Android编程经典代码集锦(复制,粘贴,浏览器调用,Toast显示,自定义Dialog等)

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.jb51.net");
intent.setdata(content_url);
//调用指定浏览器—uc
intent.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>
