顯示帶圖片的Toast
Toast toast = Toast.makeText(this,R.string.app_name,Toast.LENGTH_SHORT);
LinearLayout toastLayout = (LinearLayout) toast.getView();
ImageView imageView = new ImageView(this);
imageView.setImageResource(R.mipmap.ic_launcher);
toastLayout.addView(imageView,0);
//toast.setView(toastLayout);
請(qǐng)問為什么這里最后不需要調(diào)用setView函數(shù)將toastLayout傳給toast，而只是在toastLayout這個(gè)臨時(shí)變量上addView即可？

因?yàn)椤癓inearLayout toastLayout = (LinearLayout) toast.getView();”這句中的“?toast.getView();”在創(chuàng)建linear的時(shí)候就已經(jīng)是toast的布局了，而“addView”則是給布局添加組件。
