Toast特效详解

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。

Toast.makeText(getApplicationContext(), "默认Toast样式", Toast.LENGTH_SHORT).show();

2.自定义显示位置效果:

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:

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:

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();
