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:
Intentintent=newIntent(); intent.setAction("android.intent.action.VIEW"); Uricontent_url=Uri.parse("https://www.nhooo.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
Intentintent=newIntent(Intent.ACTION_VIEW,Uri.parse("market://search?q=pname:com.acp.main")); startActivity(intent);
4、Toast一直显示
finalToasttoast=Toast.makeText(context,"toast",Toast.LENGTH_LONG); Timertimer=newTimer(); timer.schedule(newTimerTask(){ @Override publicvoidrun(){ //TODOAuto-generatedmethodstub while(flag){ toast.show(); } } },10);
5、自定义Dialog
finalDialogmInfoDlg=newDialog(context,R.style.dialog); //R.style.dialog–去掉dialog的最上面title部分 LayoutInflaterfactory=LayoutInflater.from(context); ViewnCurrView=factory.inflate(R.layout.mydialog,null); nCurrView.setBackgroundResource(R.drawable.bgline); LinearLayoutnParentLayout=(LinearLayout)nCurrView.findViewById(R.id.iparents); nParentLayout.setBackgroundResource(R.drawable.titlebgline); mInfoDlg.setContentView(nCurrView); ButtonnBt1=(Button)nCurrView.findViewById(R.id.button1); nBt1.setText("返回"); nBt1.setTypeface(Typeface.create(Typeface.SERIF,Typeface.BOLD)); nBt1.setOnClickListener(newButton.OnClickListener(){ @Override publicvoidonClick(Viewv){ //TODOAuto-generatedmethodstub mInfoDlg.dismiss(); } }); mInfoDlg.show();
R.style.dialog:
<?xmlversion="1.0"encoding="utf-8"?> <resources> <stylename="dialog"parent="@android:style/Theme.Dialog"> <itemname="android:windowNoTitle">true</item> </style> </resources>
R.drawable.titlebgline:
<?xmlversion="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。
