Question

android如何把byte数据存到内存中并转为bitmap,求高手~~~~~~~~~~~~~~~~~~~~~~~~~~~

try {
java.io.FileInputStream fosfrom = new java.io.FileInputStream(path);
byte bt[] = new byte[1024];
int c;
while ((c = fosfrom.read(bt)) > 0) {
//fosto.write(bt, 0, c); // 原来是将内容写到新文件当中
}
fosfrom.close();
} catch (Exception e) {
e.printStackTrace();
}

注释处是读出的图片文件流，现在想将此流存入内存中，然后转为bitmap
(不是存成文件，且必须用上面方法读取，因为要操作流)
如何修改？？在线等

import java.io.File;

import android.app.Activity;
import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.ImageView;

public class MainAct extends Activity {
private ImageView img;
//图片路径
private String filepath = "/sdcard/sample.jpg";

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
img = (ImageView) findViewById(R.id.img);
File file = new File(filepath);
if (file.exists()) {
Bitmap bm = BitmapFactory.decodeFile(filepath);
//将图片显示到ImageView中
img.setImageBitmap(bm);
}
}
}
