android 打开各种文件 setDataAndType action动作

Java代码 /**
* 打开文件
* @param file
*/
private void openFile(File file){
Intent intent = new Intent();
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
//设置intent的Action属性
intent.setAction(Intent.ACTION_VIEW);
//获取文件file的MIME类型
String type = getMIMEType(file);
//设置intent的data和Type属性。
intent.setDataAndType(/*uri*/Uri.fromFile(file), type);
//跳转
startActivity(intent); //这里最好try一下，有可能会报错。 //比如说你的MIME类型是打开邮箱，但是你手机里面没装邮箱客户端，就会报错。
}
/**
* 根据文件后缀名获得对应的MIME类型。
* @param file
*/
private String getMIMEType(File file) {
String type="*/*";
String fName = file.getName();
//获取后缀名前的分隔符"."在fName中的位置。
int dotIndex = fName.lastIndexOf(".");
if(dotIndex < 0){
return type;
}
/* 获取文件的后缀名*/
String end=fName.substring(dotIndex,fName.length()).toLowerCase();
if(end=="")return type;
//在MIME和文件类型的匹配表中找到对应的MIME类型。
for(int i=0;i<MIME_MapTable.length;i++){ //MIME_MapTable??在这里你一定有疑问，这个MIME_MapTable是什么？
if(end.equals(MIME_MapTable[i][0]))
type = MIME_MapTable[i][1];
}
return type;
}
MIME_MapTable是所有文件的后缀名所对应的MIME类型的一个String数组：
Java代码 <span style="white-space: pre;"> </span>private final String[][] MIME_MapTable={
//{后缀名，MIME类型}
{".3gp", "video/3gpp"},

};
这个MIME类型可能不够完整，你有要补充的吗？
