[回忆篇]android Toast大全-五种情形

转自CSDN，5年前写的第一篇技术类的文章，当时还是个小菜鸟，一转眼5年过去了

当时从知乎摘抄的别人的励志故事，激励工作不久略失意的自己（工作缺少激情），开始利用下班时间自学android开发、iOS开发、Python开发。。。

职业方向有点迷茫，就都在学。

幸运的是，公司下班较早5点多就下班了，租住在人大附近，一下班就蹭人大的自习室学习，有时蹭女友的图书馆卡去借书看。

那段日子还是挺充实的，想想现在，基本没有自己的时间，唉。。。

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.makeText(getApplicationContext(), "默认Toast样式",

     Toast.LENGTH_SHORT).show();

2.自定义显示位置效果

代码

toast = Toast.makeText(getApplicationContext(),

     "自定义位置Toast", Toast.LENGTH_LONG);

   toast.setGravity(Gravity.CENTER, 0, 0);

   toast.show();

3.带图片效果

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

 代码

new Thread(new Runnable() {

    public void run() {

     showToast();

    }

   }).start();
