如何從圖像路徑顯示縮略圖？

Question

如何在ImageView中顯示來自固定圖像路徑的縮略圖？

Answer 1

你可以從作爲圖像路徑創建圖像縮略圖：

public Bitmap getbitpam(String path){ 
    Bitmap imgthumBitmap=null; 
    try  
    { 

     final int THUMBNAIL_SIZE = 64; 

     FileInputStream fis = new FileInputStream(path); 
      imgthumBitmap = BitmapFactory.decodeStream(fis); 

     imgthumBitmap = Bitmap.createScaledBitmap(imgthumBitmap, 
       THUMBNAIL_SIZE, THUMBNAIL_SIZE, false); 

     ByteArrayOutputStream bytearroutstream = new ByteArrayOutputStream(); 
     imgthumBitmap.compress(Bitmap.CompressFormat.JPEG, 100,bytearroutstream); 


    } 
    catch(Exception ex) { 

    } 
    return imgthumBitmap; 
}
