之前也封裝過Toast工具類冤寿，但是再點(diǎn)擊時(shí)會(huì)出現(xiàn)一個(gè)問題，就死每次點(diǎn)擊后toast沒有得到及時(shí)返回送浊，而是累計(jì)顯示梦谜，多點(diǎn)幾次有可能幾分鐘都無法消失，既然測(cè)試提出了這個(gè)問題袭景，我就只能解決啦唁桩。。耸棒。荒澡。解決方法很簡(jiǎn)單，具體代碼如下

package cn.kuencheung.utils;

import android.content.Context;
import android.widget.Toast;

public final class MyToast {
    private MyToast() { }

    public static boolean isShow = true;
    public static Toast toast;

    //短時(shí)間顯示Toast
    public static void showShort(Context context, CharSequence message) {
        if (isShow) {
            if (toast == null) {
                toast = Toast.makeText(context, message, Toast.LENGTH_SHORT);
            } else {
                toast.cancel();//關(guān)閉吐司顯示
                toast = Toast.makeText(context, message, Toast.LENGTH_SHORT);
            }
            toast.show();
        }
    }

    //短時(shí)間顯示Toast
    public static void showShort(Context context, int message) {
        if (isShow) {
            if (toast == null) {
                toast = Toast.makeText(context, message, Toast.LENGTH_SHORT);
            } else {
                toast.cancel();//關(guān)閉吐司顯示
                toast = Toast.makeText(context, message, Toast.LENGTH_SHORT);
            }
            toast.show();
        }
    }

    //長(zhǎng)時(shí)間顯示Toast
    public static void showLong(Context context, CharSequence message) {
        if (isShow) {
            if (toast == null) {
                toast = Toast.makeText(context, message, Toast.LENGTH_LONG);
            } else {
                toast.cancel();//關(guān)閉吐司顯示
                toast = Toast.makeText(context, message, Toast.LENGTH_LONG);
            }
            toast.show();
        }
    }

    //長(zhǎng)時(shí)間顯示Toast
    public static void showLong(Context context, int message) {
        if (isShow) {
            if (toast == null) {
                toast = Toast.makeText(context, message, Toast.LENGTH_LONG);
            } else {
                toast.cancel();//關(guān)閉吐司顯示
                toast = Toast.makeText(context, message, Toast.LENGTH_LONG);
            }
            toast.show();
        }
    }

    //自定義顯示Toast時(shí)間
    public static void show(Context context, CharSequence message, int duration) {
        if (isShow) {
            Toast.makeText(context, message, duration).show();
        }
    }

    //自定義顯示Toast時(shí)間
    public static void show(Context context, int message, int duration) {
        if (isShow) {
            Toast.makeText(context, message, duration).show();
        }
    }
}

其實(shí)到這已經(jīng)算是完成了与殃，可尼瑪leakcary已檢測(cè)单山，內(nèi)存泄露了，噢幅疼，toast定義的靜態(tài)成員變量米奸，在activity和fragment的ondestory()方法走完之后toast沒有得到及時(shí)銷毀，解決方法：在ondestory()方法結(jié)束之前爽篷，判斷toast是否為null,不為null,則z置為null.

@Override
protected void onDestroy() {
    super.onDestroy();
    if (MyToast.toast != null) MyToast.toast = null;
}

如此悴晰，便已大功告成！
