1.MainActivity中：

package com.example.administrator.toast;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.TextView;

public class MainActivity extends AppCompatActivity implements View.OnClickListener {

    private TextView textView, textView2;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        initView();
        setListener();
    }

    //初始化view
    private void initView() {
        textView = (TextView) findViewById(R.id.textView);
        textView2 = (TextView) findViewById(R.id.textView2);
    }

    //设置监听
    private void setListener() {
        textView.setOnClickListener(this);
        textView2.setOnClickListener(this);
    }

    @Override
    public void onClick(View view) {
        switch (view.getId()) {
            case R.id.textView:
                ToastUtils toastUtil = new ToastUtils(MainActivity.this, R.layout.item, R.drawable.aa, "请输入电话");
                break;
            case R.id.textView2:
                ToastUtils toastUtil2 = new ToastUtils(MainActivity.this, R.layout.item, R.drawable.bb, "请输入班级");
                break;
        }
    }
}
2.工具类：
package com.example.administrator.toast;

import android.content.Context;
import android.view.Gravity;
import android.view.LayoutInflater;
import android.view.View;
import android.widget.ImageView;
import android.widget.TextView;
import android.widget.Toast;

/**
 * Created by Administrator on 2017/10/27.
 */

public class ToastUtils {
    private Toast mToast;
    private String message;

    public ToastUtils(Context context, int layoutId, int iconResId, String msg) {
        message = msg;
        LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        //自定义布局
        View view = inflater.inflate(layoutId, null);
        //自定义toast文本
        TextView mTextView = (TextView) view.findViewById(R.id.toast_msg);
        mTextView.setText(msg);
        ImageView imageView = view.findViewById(R.id.image);
        imageView.setImageResource(iconResId);

        if (mToast == null) {
            mToast = new Toast(context);
        }
        //设置toast居中显示
        mToast.setGravity(Gravity.CENTER, 0, 0);
        mToast.setDuration(Toast.LENGTH_SHORT);
        mToast.setView(view);
        mToast.show();
    }
}

3.布局：activity_main

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"

    tools:context="com.example.administrator.toast.MainActivity">

    <TextView
        android:id="@+id/textView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:gravity="center"
        android:text="电话" />

    <TextView
        android:id="@+id/textView2"
        android:layout_width="wrap_content"
