自定义一个简单的带图片的Toast

自定义Toast比较简单，只需要用Java代码编写布局组件，然后调用Toast的setView(View view)方法将自定义的布局组件设置进去即可

效果图：

package com.demo;

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.ImageButton;
import android.widget.ImageView;
import android.widget.LinearLayout;
import android.widget.TextView;
import android.widget.Toast;

public class ToastTest extends Activity {

    private Button show;
    private TextView textView;
    private ImageView imageView;
    private Toast toast;
    private LinearLayout lnl;  //用于自定义Toast的布局
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        //相关组件的初始化
        show=(Button) findViewById(R.id.show);
        toast=new Toast(ToastTest.this);
        lnl=new LinearLayout(ToastTest.this);
        imageView=new ImageButton(ToastTest.this);
        textView=new TextView(ToastTest.this);

        imageView.setImageResource(R.drawable.icon);
        textView.setText("Toast with picture and text");

        //lnl中包含了一个ImageView和一个TextView
        lnl.addView(imageView);
        lnl.addView(textView);
        toast.setView(lnl);

        show.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                    //设置toast以lnl这个布局来显示内容
                toast.show();
                toast.setDuration(300);
            }
        });



    }
}
