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("http://www.zzvips.com");
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>
