private string getsdcardpath(){
file sdcarddir = null;
//判断sdcard是否存在
boolean sdcardexist = environment.getexternalstoragestate().equals(android.os.environment.media_mounted);
if(sdcardexist){
sdcarddir = environment.getexternalstoragedirectory();
}
return sdcarddir.tostring();
}
由于要对sdcard进行操作,所以别忘记了在manifest.xml文件中赋以对sdcard的读写权限:
<uses-permission android:name="android.permission.write_external_storage"/>
