Android從java代碼添加可繪製圖像？

Question

我需要在TextView中插入一個我從代碼中從網上下載的drawable。所以我不能手動將圖像放在res和R.drawable中。

我該如何使用它？

Answer 1

步驟：

1）下載圖像

2）轉換通過調用水木清華這樣來繪製

3）設置繪製到的TextView：

textView.setCompoundDrawablesWithIntrinsicBounds(R.drawable.icon, 0, 0, 0); 

Answer 2

試試這個

try { 
    /* Open a new URL and get the InputStream to load data from it. */ 
    URL aURL = new URL("ur Image URL"); 
    URLConnection conn = aURL.openConnection(); 
    conn.connect(); 
    InputStream is = conn.getInputStream(); 
    /* Buffered is always good for a performance plus. */ 
    BufferedInputStream bis = new BufferedInputStream(is); 
    /* Decode url-data to a bitmap. */ 
    Bitmap bm = BitmapFactory.decodeStream(bis); 
    bis.close(); 
    is.close(); 

    Drawable d =new BitmapDrawable(bm); 
    d.setId("1"); 
    textview.setCompoundDrawablesWithIntrinsicBounds(0,0,1,0);// wherever u want the image relative to textview 
    } catch (IOException e) { 
    Log.e("DEBUGTAG", "Remote Image Exception", e); 
    }
