Toast Dialog的封装（一）

  
系统的toast并不能满足我们的要求，1，布局简单  2，多次点击或重复吐司。本菜稍稍的封装了一下，直接上代码
首先我们要准备一个布局 (Toast)，另附背景的shape代码
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/ll_toast_root"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@drawable/toast_dark_shape"
    android:orientation="vertical"
    android:padding="8dp">

    <TextView
        android:id="@+id/text"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textColor="#FFF" />
</LinearLayout>

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">
    <solid
        android:color="@color/dark"></solid>
    <corners
        android:radius="6dp"></corners>
</shape>
资源准备好了，我们来封装吧

public class ToastCommon {
    private static ToastCommon toastCommom;
    private static Toast toast;
    private ToastCommon(){
    }
    private static Handler mHandler = new Handler();
    private static Runnable r = new Runnable() {
        public void run() {
            toast.cancel();
            toast=null;//toast隐藏后，将其置为null
        }
    };
    /**
     * 显示Toast
     * @param context
     * @param root
     * @param tvString
     */
    public static void toastShortShow(Context context,ViewGroup root,String tvString){
        View layout = LayoutInflater.from(context).inflate(R.layout.toast_diy,root);

        TextView text = (TextView) layout.findViewById(R.id.text);

text.setText(tvString);
        mHandler.removeCallbacks(r);
        if (toast == null) {//只有mToast==null时才重新创建，否则只需更改提示文字
            toast = new Toast(context);
            toast.setGravity(Gravity.BOTTOM, 0, 100);
            toast.setDuration(Toast.LENGTH_SHORT);
            toast.setView(layout);
        }
        mHandler.postDelayed(r, 1000);//延迟1秒隐藏toast
        toast.show();
    }
}

写好这个类，在代码中调用吧（就是这么简单）
ToastCommon.toastShortShow(context, null, "打开困难登录界面");



简单吧，下面来封装下Dialog,每次我们新建dialog是不是有很多重复代码，系统自带有时还不能满足我们，继续，上代码—> 封装Dialog(我简单的写了一下，只有两种，同学可自行添加)

/**
 * Created by pc-004 on 2015/8/14.
 */
public abstract class DialogCommon {
    /**
     * 系统自带的Dialog
     *
     * @param context
     * @param icon
     * @param title
     * @param message
     * @param positiveBtnText
     * @param negativeButtonBtnText
     */
    public void dialogShowNavite(Context context, int icon, String title, String message, String positiveBtnText, String negativeButtonBtnText) {
        //先new出一个监听器，设置好监听
        DialogInterface.OnClickListener dialogOnclicListener = new DialogInterface.OnClickListener() {

            @Override
            public void onClick(DialogInterface dialog, int which) {
                switch (which) {
                    case Dialog.BUTTON_POSITIVE:
                        positiveClick();
                        dialog.dismiss();
                        break;
                    case Dialog.BUTTON_NEGATIVE:
                        negativeClick();
                        dialog.dismiss();
                        break;
//                    case Dialog.BUTTON_NEUTRAL:
//                        Toast.makeText(MainActivity.this, "忽略" + which, Toast.LENGTH_SHORT).show();
//                        break;
                }
            }
        };
        //dialog参数设置
        AlertDialog.Builder builder = new AlertDialog.Builder(context);  //先得到构造器
        builder.setTitle(title); //设置标题
        builder.setMessage(message); //设置内容
        builder.setIcon(icon);//设置图标，图片id即可
        builder.setPositiveButton(positiveBtnText, dialogOnclicListener);

        builder.setNegativeButton(negativeButtonBtnText, dialogOnclicListener);
//        builder.setNeutralButton("忽略", dialogOnclicListener);
        builder.create().show();
    }

    /**
     * 自定义dialog
     *
     * @param context
     * @param viewGroup
     * @param leftBtn
     * @param rightBtn
     * @param title
     */
    public void dialogShowDiy(Context context, ViewGroup viewGroup, String leftBtn, String rightBtn, String title) {

        final Dialog dialog = new AlertDialog.Builder(context).create();
        dialog.setContentView(viewGroup);
        final TextView tv_left_bottom_dialog = (TextView) viewGroup.findViewById(R.id.tv_left_bottom_dialog);
        final TextView tv_right_bottom_dialog = (TextView) viewGroup.findViewById(R.id.tv_right_bottom_dialog);
        final TextView tv_title_dialog = (TextView) viewGroup.findViewById(R.id.tv_title_dialog);

        tv_left_bottom_dialog.setText("登录");
        tv_right_bottom_dialog.setText("重新输入");
        tv_title_dialog.setText("此号码已注册，是否立即登录？");
        tv_left_bottom_dialog.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                leftBtnClick();
                dialog.cancel();
            }
        });

        tv_right_bottom_dialog.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                rightBtnClick();
                dialog.cancel();
            }
        });
        dialog.show();
    }

    /**
     * 原生的dialog
     */
    public abstract void positiveClick();

    public abstract void negativeClick();

    /**
     * 自定义dialog
     */
    public abstract void leftBtnClick();

    public abstract void rightBtnClick();
}
好了，开始在代码中使用吧

    /**
     * 显示提示窗
     */
    private void dialogShow() {
        DialogCommon dialogCommon = new DialogCommon() {
            @Override
            public void positiveClick() {
                LoginActivity.handler.sendEmptyMessage(1);
            }

            @Override
            public void negativeClick() {

            }

            @Override
            public void leftBtnClick() {

            }

            @Override
            public void rightBtnClick() {

            }


        };
        dialogCommon.dialogShowNavite(context, R.mipmap.ic_launcher, getString(R.string.hint),
                "超过尝试次数，请使用验证码登录", getString(R.string.sure),
                getString(R.string.cancle));
    }


    /**
     * 展现自定义dialog
     */
    private void showDialog() {
        DialogCommon dialogCommon = new DialogCommon() {
            @Override
            public void positiveClick() {

            }

            @Override
            public void negativeClick() {

            }

            @Override
            public void leftBtnClick() {
                Intent intent = new Intent(RegisterActivity.this, LoginActivity.class);
                startActivity(intent);
            }

            @Override
            public void rightBtnClick() {
                etxtTel.setFocusable(true);
                etxtTel.setFocusableInTouchMode(true);
                etxtTel.requestFocus();
                etxtTel.requestFocusFromTouch();
                //调用系统软键盘
                InputMethodManager inputManager = (InputMethodManager)
                        etxtTel.getContext().getSystemService(Context.INPUT_METHOD_SERVICE);
                inputManager.showSoftInput(etxtTel, 0);
            }
        };
        LayoutInflater inflater = LayoutInflater.from(this);
        RelativeLayout relativeLayout = (RelativeLayout) inflater.inflate(R.layout.dialog_customer, null);
        dialogCommon.dialogShowDiy(RegisterActivity.this, relativeLayout, "登录", "重新输入", "此号码已注册，是否立即登录？");
    }
是不是很简单，布局我就不给大家发了，有什么问题，欢迎留言
