本文详细介绍了在Android中创建不同类型的Toast消息的方法，包括普通Toast、改变位置的Toast、添加图片的Toast以及添加自定义View的Toast，并且演示了如何创建长时间显示的Toast效果，类似于Dialog。

1、最常用的toast：

toast.makeText(this, TOASTBTN_1, Toast.LENGTH_LONG).show();

2、改变位置的toast：

toast = Toast.makeText(getApplicationContext(), TOASTBTN_2,
                   Toast.LENGTH_LONG);
           toast.setGravity(Gravity.CENTER, 0, 0);
           toast.show();

3、添加图片的toast：

toast = Toast.makeText(getApplicationContext(), TOASTBTN_3,
                   Toast.LENGTH_LONG);
           toast.setGravity(Gravity.CENTER, 50, -100);
           LinearLayout layout = (LinearLayout) toast.getView();
           ImageView image = new ImageView(getApplicationContext());
           image.setImageResource(R.drawable.wallpaper_tree_small);
           layout.addView(image, 0);
           toast.show();

4、添加View的toast（算的上是最简单的自定义View）：

LayoutInflater inflater = getLayoutInflater();
           View view = inflater.inflate(R.layout.userdefinedtoast,
                   (ViewGroup) findViewById(R.id.toast_layout));
           TextView txtView_Title = (TextView) view
                   .findViewById(R.id.txt_Title);
           TextView txtView_Context = (TextView) view
                   .findViewById(R.id.txt_context);
           ImageView imageView = (ImageView) view
                   .findViewById(R.id.image_toast);
           toast = new Toast(getApplicationContext());
           toast.setGravity(Gravity.CENTER, 0, 0);
           toast.setDuration(Toast.LENGTH_LONG);
           toast.setView(view);
           toast.show();

5、长时间显示的toast（其实就是dialog）：

LayoutInflater inflater1 = getLayoutInflater();
           View view1 = inflater1.inflate(R.layout.userdefinedtoast,
                   (ViewGroup) findViewById(R.id.toast_layout));
           TextView txtView_Title1 = (TextView) view1
                   .findViewById(R.id.txt_Title);
           TextView txtView_Context1 = (TextView) view1
                   .findViewById(R.id.txt_context);
           ImageView imageView1 = (ImageView) view1
                   .findViewById(R.id.image_toast);
           builder = new AlertDialog.Builder(this);
           builder.setView(view1);
           dialog = builder.create();
           dialog.show();
