圖像應在android系統

這被轉發到下一個畫面是我的代碼圖像應在android系統

package com.marakana;

      m.setAa(aa); 
     Toast.makeText(getBaseContext(),aa,1000).show(); 
     outStream.write(data); 
     outStream.close(); 
     Log.d(TAG, "onPictureTaken - wrote bytes: " + data.length); 
     Intent i=new Intent(); 
     i.setClassName("com.marakana", "com.marakana.image"); 
     startActivity(i); 
     } catch (FileNotFoundException e) { // <10> 
     e.printStackTrace(); 
     } catch (IOException e) { 
     e.printStackTrace(); 
     } finally { 
     } 
     Log.d(TAG, "onPictureTaken - jpeg"); 
    }

訪問路徑讓你的問題更精確和易於閱讀。現在它真的很痛苦讀這個.. – Javanator 2011-02-02 08:34:52

這是我的代碼...和問題？ – 2013-07-13 14:25:30

我認爲其更好您發送您的路徑下一個活動。所以你可以從這個活動中讀到它。

String path = String.format("/sdcard/DCIM/%d.jpg",System.currentTimeMillis()); 
outStream = new FileOutputStream(path); 
//other codes 
Intent i=new Intent(); 
i.setClassName("com.marakana", "com.marakana.image"); 
i.putExtra("path", path); 
startActivity(i);

所以，你可以通過

String path = getIntent().getExtra("path"); 
//so you can create drawable or bitmap using this path

i.putExtra("img", data);

然後在另一個活動只是使用

getIntent().getExtra("img");
