Android 备忘录

android中如何改变AudioButton的显示图片 ：

android:button="@drawable/search_btn_radio"

android中调用Google Search:

Intent search = new Intent(Intent.ACTION_WEB_SEARCH);
search.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
search.putExtra(SearchManager.QUERY, "eoeAndroid");
final Bundle appData = getIntent().getBundleExtra(SearchManager.APP_DATA);
if (appData != null) {
search.putExtra(SearchManager.APP_DATA, appData);
}

startActivity(search);

android 打开本地html文件：

Intent intent=new Intent();
intent.setAction("android.intent.action.VIEW");

Uri CONTENT_URI_BROWSERS = Uri.parse("content://com.android.htmlfileprovider/sdcard/123.html");

intent.setData(CONTENT_URI_BROWSERS);
intent.setClassName("com.android.browser", "com.android.browser.BrowserActivity");

startActivity(intent);

假设要打开的本地html文件存放在如下路径
/sdcard/123.html

android 打开本地文件：

Intent in3 = new Intent();
in3.setAction("android.intent.action.VIEW");
Uri uri3 = Uri.parse("file://"+searchInfo.absolutePath);
in3.setDataAndType(uri3, "video/*");
startActivity(in3);

android打开其他程序Activity：

Uri uri = Uri.parse("package:system.app.Mms");

Intent intent = new Intent(Intent.ACTION_MAIN);

intent.addCategory(Intent.CATEGORY_LAUNCHER);

//这里的className里的信息都可以从eclipse测logcat里面得到

intent.setClassName("com.android.mms", "com.androis.mms.ui.ConversationList");

mLauncher.startActivity(intent);

查询短信数据库：

String strUriInbox = "content://sms";
Uri uriSms = Uri.parse(strUriInbox);
Cursor c_groups = managedQuery( uriSms , new String[] { "date","person" }, select, null, "date DESC");

strColumnName=_id strColumnValue=48 //短消息序号
strColumnName=thread_id strColumnValue=16 //对话的序号（conversation）
strColumnName=address strColumnValue=+8613411884805 //发件人地址，手机号
strColumnName=person strColumnValue=null //发件人，返回一个数字就是联系人列表里的序号，陌生人为null
strColumnName=date strColumnValue=1256539465022 //日期 long型，想得到具体日期自己转换吧！
strColumnName=protocol strColumnValue=0 //协议
