Toast是Android中用来显示显示信息的一种机制，和Dialog不一样的是，Toast是没有焦点的，而且Toast显示的时间有限，过一定的时间就会自动消失。默认效果,代码为：Toast.makeText(getApplicationContext(), "默认Toast样式", Toast.LENGTH_SHORT).show();
自定义显示位置效果,代码为：

toast = Toast.makeText(getApplicationContext(), "自定义位置Toast", Toast.LENGTH_LONG); toast.setGravity(Gravity.CENTER, 0, 0); toast.show();
带图片效果,代码为：

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();
完全自定义效果,代码为：

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();
其他线程,代码为：

new Thread(new Runnable() { public void run() { showToast(); } }).start();
