Android奇效，五种Toast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。

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();
