本文介绍如何使用Android中的Toast组件展示不同样式的消息提示，包括默认样式、自定义位置、带图片及完全自定义样式等五种实现方法。

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();
