如何在Android开发中熟练使用五种Toast的特效

Answer 1

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();
