在写Toast之前我们应该需要了解下 Toast是干什么的 或者说他是用来完成那些事情的,为了便于大家理解呢,我以我自己理解的程度来给大家举例子 Toast 英语是 “吐司”的意思,但是为什么要将它取这个名字我不是很理解,现在我说下我理解的toast 的用途,我们可以将 toast理解成为一种通知,也就是我们在操作Android 之后 Android系统反馈给我们的信息,或者数据!

我们将toast理解为是一种通知,下面的样式我们就可以理解为不同形式的通知了,例如有的通知就是一张白纸然后上面的黑字,还有的或许就华丽些了,采用的是 彩纸 和 彩笔 后来更华丽了,那我估计就应该是 “请柬” 这种样子了!可以做到 图文并茂的效果了!

下面让我们一起来看看这些 “通知单”的效果!

 

Toast用于向用户显示一些帮助/提示。下面我做了5中效果,来说明Toast的强大,定义一个属于你自己的Toast。

1.默认效果

代码

toast = Toast.makeText(getApplicationContext(),
"带图片的Toast", Toast.LENGTH_LONG);
toast.setGravity(Gravity.CENTER, 0, 0);
LinearLayout toastView = (LinearLayout) toast.getView();
ImageView imageCodeProject = new ImageView(getApplicationContext());
imageCodeProject.setImageResource(R.drawable.icon);
toastView.addView(imageCodeProject, 0);
toast.show();


 

4.完全自定义效果

代码:

LayoutInflater inflater = getLayoutInflater();
View layout = inflater.inflate(R.layout.custom,
(ViewGroup) findViewById(R.id.llToast));
ImageView image = (ImageView) layout
.findViewById(R.id.tvImageToast);
image.setImageResource(R.drawable.icon);
TextView title = (TextView) layout.findViewById(R.id.tvTitleToast);
title.setText("Attention");
TextView text = (TextView) layout.findViewById(R.id.tvTextToast);
text.setText("完全自定义Toast");
toast = new Toast(getApplicationContext());
toast.setGravity(Gravity.RIGHT | Gravity.TOP, 12, 40);
toast.setDuration(Toast.LENGTH_LONG);
toast.setView(layout);
toast.show();


 

5.其他线程

public void run() {
showToast();
}
}).start();
