uj5u.com熱心網友回復：
android.graphics.Rect android.graphics.drawable.Drawable.getBounds()' on a null object reference你物件是空的 是不是沒初始化物件 直接用了
uj5u.com熱心網友回復：
.NullPointerException：空指標例外，去78 行打個斷點，debug一下看看那個物件是null；要學會看例外資訊uj5u.com熱心網友回復：
DynamicDrawableSpan.java: 這個類的 第78行uj5u.com熱心網友回復：
把相關代碼貼出來uj5u.com熱心網友回復：
這個應該是呼叫方法getBounds()的物件是空物件，也是就null。通過斷點除錯一下應該能夠看到那個物件的值。轉載請註明出處，本文鏈接：https://www.uj5u.com/yidong/48851.html
