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。
