擷取Android “/asset”目錄資料

14.2.1.1.擷取AssetManager對象

AssetManager manage = getAssets();

14.2.1.2.擷取InputStream對象

InputStream open= manage.open("newareaall.json");

14.2.1.3.将InputStream 對象轉換成字元串

ByteArrayOutputStream content = new ByteArrayOutputStream();

int readBytes = 0;

byte[] sBuffer = new byte[1024];//用來儲存每次讀取到的字元

while ((readBytes = open.read(sBuffer)) != -1) {

content.write(sBuffer, 0, readBytes);

}

//将内容轉化為字元串

String result=new String(content.toByteArray());

14.2.1.4.将InputStream 對象轉換成圖檔Bitmap image = BitmapFactory.decodeStream(open);

14.2.1.5.擷取/assets某個檔案夾下的全部内容(圖檔集合)

demofiles=demoam.list("food");

for(int i=0;i<demofiles.length;i++){

demoinputStream=demoam.open("food/"+demofiles[i]);

byte[] reader = new byte[demoinputStream.available()];

while((demoinputStream.read(reader))!=-1){

writeDemoFile(reader,demofoodfile,demofiles[i]);

}

}
