【Android】消息提示toast和context 后两位是x、y的距离。Toast.makeText(this, 显示的内容, 显示时间长度).show();前者生命周期长，后者短，用完就回收。this:当前activity对象。阅读详情

Toast是安卓非常常用的消息弹框之一，但是原生的弹框过于朴素，无法适应不同场景的样式需求，因此设计一个类似于Toasty的弹框构建工具。

不废话直接上代码

import android.content.Context;
import android.os.Looper;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ImageView;
import android.widget.LinearLayout;
import android.widget.TextView;
import android.widget.Toast;
import android.widget.ImageView.ScaleType;
import android.widget.LinearLayout.LayoutParams;
import androidx.annotation.Nullable;
import com.cpk.yeahtoast.R.color;
import com.cpk.yeahtoast.R.drawable;

public class YeahToast {
    private static final String TAG = YeahToast.class.getSimpleName();
    public static final int STYLE_NO = 0;
    public static final int STYLE_INFO = 1;
    public static final int STYLE_WARN = 2;
    public static final int STYLE_ERROR = 3;
    public static final int STYLE_SUCCESS = 4;
    private static YeahToast.StyleToast styleToast = null;

public static void show(Context context, String text, @Nullable Integer length) {
        show(context, STYLE_NO , text, length);
    }

    public static void showInfo(Context context, String text, @Nullable Integer length) {
        prepare(context, STYLE_INFO , text, length).show();
    }

    public static void showError(Context context, String text, @Nullable Integer length) {
        prepare(context, STYLE_ERROR , text, length).show();
    }

    public static void showWarn(Context context, String text, @Nullable Integer length) {
        prepare(context, STYLE_WARN , text, length).show();
    }

    public static void showSuccess(Context context, String text, @Nullable Integer length) {
        prepare(context, STYLE_SUCCESS , text, length).show();
    }

    protected static StyleToast prepare(Context context, int style, String text, @Nullable Integer length) {
        if (styleToast != null) {
            styleToast.cancel();
        }
styleToast = new YeahToast.StyleToast(context, style, text, length);
        return styleToast;
    }
}

StyleToast是用于设置Toast样式的封装类，可以设为子类，也可以新建一个类。带样式的弹框是用Toast的setView方法将一个自定义的布局作为toast显示内容，本封装类设置Toast的布局有一个图标和文本。

        Toast toast;
        ViewGroup view;
        TextView tv;
        ImageView icon;

        public StyleToast(Context context, int style, String message, @Nullable Integer length) {

            this.view.setPadding(8, 8, 8, 8);
            this.tv = new TextView(context);

            imageLp.setMargins(8, 8, 8, 8);
            this.icon = new ImageView(context);

            this.icon.setLayoutParams(imageLp);

            this.view.addView(this.tv);
            this.view.setLayoutParams(new android.view.ViewGroup.LayoutParams(-2, -2));
            this.toast.setView(this.view);
            this.toast.setDuration(length == null ? 0 : length);
            switch(style) {
            case 1:
                this.view.setBackgroundResource(drawable.toast_style_info);
                this.icon.setImageResource(drawable.ic_error_outline_white_24dp);
                break;
            case 2:

                this.icon.setImageResource(drawable.ic_warning_white_24dp);
                break;
            case 3:
                this.view.setBackgroundResource(drawable.toast_style_error);
                this.icon.setImageResource(drawable.ic_close_white_24dp);
                break;
            case 4:
                this.view.setBackgroundResource(drawable.toast_style_success);
                this.icon.setImageResource(drawable.ic_done_black_24dp);
                break;
            default:
                this.view.setBackgroundResource(drawable.toast_style_default);
                this.icon.setVisibility(8);
            }

        }

        public void show() {
            this.toast.show();
        }

        private void cancel() {
            this.toast.cancel();
        }
    }

所有资源都是xml文件，放在drawable里。

使用方式很简单，比如想在Activity弹出一个长警告就用YeahToast.showWarn(this,"warn!",Toast.LENGTH_LONG);

因为Toast是系统默认的一种弹窗，无法自定义时长，只能为Toast.LENGTH_SHORT（2.5秒）或Toast.LENGTH_LONG（3秒），对自定义的支持不是很好，而且显示内容也受限制(比如不能播放声音)，在Android9版本中甚至不支持播放长Toast，且在11版本中弃用了setView方法，这意味着本工具类可能就要失效了。
