[Android]_ch7.3_存取assets目錄內的資源

取得assets目錄內的檔案內容是透過較低階的IO方式，並使用AssetManager類別的功能

btn4.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
AssetManager AM=getAssets();
try {
InputStream is=AM.open("A2019.txt");
int num=is.available();
byte data[]=new byte[num];
is.read(data);
String string=new String(data);
tv4.setText("檔案大小:"+num+"位元組\n"+string);
is.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

}
