本文提供了一个 Android Toast 的示例代码，展示了如何使用 Toast 进行基本提示消息显示、自定义位置、带图片的消息提示以及完全自定义视图的 Toast。通过不同按钮触发各种 Toast 显示效果。

package com.wjq.toast;


import android.app.Activity;
import android.os.Bundle;
import android.os.Handler;
import android.view.Gravity;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.view.View.OnClickListener;
import android.widget.ImageView;
import android.widget.LinearLayout;
import android.widget.TextView;
import android.widget.Toast;


public class Main extends Activity implements OnClickListener {
	Handler handler = new Handler();


	@Override
	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.main);


		findViewById(R.id.btnSimpleToast).setOnClickListener(this);
		findViewById(R.id.btnSimpleToastWithCustomPosition).setOnClickListener(
				this);
		findViewById(R.id.btnSimpleToastWithImage).setOnClickListener(this);
		findViewById(R.id.btnCustomToast).setOnClickListener(this);
		findViewById(R.id.btnRunToastFromOtherThread).setOnClickListener(this);


	}


	public void showToast() {
		handler.post(new Runnable() {


			@Override
			public void run() {
				Toast.makeText(getApplicationContext(), "我来自其他线程！",
						Toast.LENGTH_SHORT).show();


			}
		});
	}


	@Override
	public void onClick(View v) {
		Toast toast = null;
		switch (v.getId()) {
		case R.id.btnSimpleToast:
			Toast.makeText(getApplicationContext(), "默认Toast样式",
					Toast.LENGTH_SHORT).show();
			break;
		case R.id.btnSimpleToastWithCustomPosition:
			toast = Toast.makeText(getApplicationContext(),
					"自定义位置Toast", Toast.LENGTH_LONG);
			toast.setGravity(Gravity.CENTER, 0, 0);
			toast.show();
			break;
		case R.id.btnSimpleToastWithImage:
			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();
			break;
		case R.id.btnCustomToast:
			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();
			break;
		case R.id.btnRunToastFromOtherThread:
			new Thread(new Runnable() {
				public void run() {
					showToast();
				}
			}).start();
			break;


		}


	}
}
