二。自定義Toast 

二。一 自定義Toast類代碼：

package com.chencheng.utils;

import android.content.Context;

import android.view.Gravity;

import android.view.LayoutInflater;

import android.view.View;

import android.widget.TextView;

import android.widget.Toast;

import com.yuchen.meituan.R;

public class ToastUtil {

private static Toast toast;

public static void showToast(Context context, String text) {

// Toast toast = Toast.makeText(this, "toast", Toast.LENGTH_LONG);

// 如果之前有任務，就取消

if (toast != null) {

toast.cancel();

}

toast = new Toast(context);

View view = LayoutInflater.from(context).inflate(R.layout.toast_custom,

null);

TextView tvText = (TextView) view.findViewById(R.id.tv_content);

tvText.setText(text);

// toast.setBackground();

toast.setView(view);

toast.setGravity(Gravity.BOTTOM, 0, 100);

toast.setDuration(Toast.LENGTH_SHORT);

toast.show();

}

private ToastUtil() {

}

}

        android:layout_width="wrap_content"

        android:layout_height="wrap_content"

        android:layout_centerHorizontal="true"

        android:layout_centerVertical="true"

        android:padding="5dp"

        android:background="@color/green">

        <TextView

            android:id="@+id/tv_content"

            android:layout_centerVertical="true"

            android:text="Medium Text"

            android:textColor="#ffffff"

            android:textSize="15sp" />

    </RelativeLayout>

</RelativeLayout>
