android Toast五种酷炫样式

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.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();
