来自同事_Smile的封装，记录学习一下

1、核心代码

public class ToastDialog extends Dialog {

    public static final int DIALOG_SHOW_TIME_SHORT = 3000;
    public static final int DIALOG_SHOW_TIME_LONG = 5000;

    /**
     * 显示时间，单位毫秒，默认3秒
     */
    private int showTime = DIALOG_SHOW_TIME_SHORT;
    private int toastDialogTioIconId = 0;
    private Object toastShowContent;

    public ToastDialog(Context context) {
        super(context, R.style.style_dialog);
    }

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setCanceledOnTouchOutside(false);
        setCancelable(false);
        setContentView(R.layout.dialog_customize_toast);

        initView();
    }

    private void initView() {
        ImageView ivToastDialogIcon = (ImageView) findViewById(R.id.iv_dialog_toast_icon);
        if (getToastDialogTioIconId() != 0) {
            ivToastDialogIcon.setImageResource(getToastDialogTioIconId());
        }

        TextView tvToastDialogContent = (TextView) findViewById(R.id.tv_dialog_toast_content);
        ViewUtils.loadContent(tvToastDialogContent, getToastShowContent());
    }

    @Override
    public void show() {
        dismissDialog();
        super.show();
    }

    private void dismissDialog() {
        Timer timer = new Timer();
        timer.schedule(new TimerTask() {
            @Override
            public void run() {
                dismiss();
            }
        }, getShowTime());
    }

    @Override
    public void dismiss() {
        super.dismiss();
    }

    @Override
    public void onBackPressed() {
        return;
    }

    private int getShowTime() {
        return showTime;
    }

    /**
     * 设置显示时间，单位毫秒
     * @param showTime 时间
     */
    public void setShowTime(int showTime) {
        this.showTime = showTime;
    }

    private int getToastDialogTioIconId() {
        return toastDialogTioIconId;
    }

    /**
     * 设置显示图标
     * @param toastDialogTioIconId 图标ID
     */
    public void setToastDialogTioIconId(int toastDialogTioIconId) {
        this.toastDialogTioIconId = toastDialogTioIconId;
    }

    private Object getToastShowContent() {
        return toastShowContent;
    }

    /**
     * 显示内容
     * @param toastShowContent 内容
     */
    public void setToastShowContent(Object toastShowContent) {
        this.toastShowContent = toastShowContent;
    }
}

2、R.layout.dialog_customize_toast布局代码

<?xml version="1.0" encoding="utf-8"?>
<!--自定义Toast样式dialog弹框布局-->
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="@dimen/dimen_515"
    android:layout_height="@dimen/dimen_320"
    android:background="@drawable/bg_round_white_shape"
    android:gravity="center"
    android:padding="@dimen/dimen_20"
    android:orientation="vertical">

    <ImageView
        android:id="@+id/iv_dialog_toast_icon"
        style="@style/style_wrap_content"
        android:contentDescription="@null"/>

    <TextView
        android:id="@+id/tv_dialog_toast_content"
        style="@style/style_wrap_content"
        android:layout_marginTop="@dimen/dimen_20"
        android:textSize="@dimen/text_26"
        android:textColor="@color/c_black_2"
        android:maxLines="2"/>

</LinearLayout>

3、 R.style.style_dialog 样式代码

 <!-- 自定义DialogActivity样式-->
    <style name="style_dialog" parent="android:style/Theme.Dialog">
        <item name="android:windowBackground">@android:color/transparent</item>
        <item name="android:windowFrame">@null</item>
        <item name="android:windowNoTitle">true</item>
        <item name="android:windowIsFloating">true</item>
        <item name="android:windowIsTranslucent">true</item>
        <item name="android:windowContentOverlay">@null</item>
        <item name="android:windowFullscreen">true</item>
        <item name="android:windowAnimationStyle">@android:style/Animation.Dialog</item>
        <item name="android:backgroundDimEnabled">true</item>
    </style>
