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("https://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&＃63;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：
<&＃63;xml version="1.0"encoding="utf-8"&＃63;>
R.drawable.titlebgline：
