Android--自定義彈出框-自定義dialog

項目要用到彈出框，還要和蘋果的樣式一樣(Android真是沒地位),所以就自己定義了一個，不是很像(主要是沒圖)，但是也還可以。

廢話不多說了，直接上代碼

1、先看布局文件

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:padding="20dp"
    android:orientation="vertical">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:gravity="center_horizontal"
        android:background="@drawable/custom_dialog_background"
        android:orientation="vertical">

        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:gravity="center_horizontal"
            android:orientation="vertical">

            <TextView
                android:id="@+id/tv_title_custom_dialog"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_marginTop="20dp"
                android:text="提醒"
                android:textColor="#000"
                android:textSize="18dp" />

            <TextView
                android:id="@+id/tv_message_custom_dialog"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_marginTop="10dp"
                android:text="您確定要取消訂單嗎" />
        </LinearLayout>

        <View
            android:layout_width="match_parent"
            android:layout_height="0.5dp"
            android:layout_marginTop="20dp"
            android:background="#dfdfdf" />

        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:orientation="horizontal">

            <Button
                android:id="@+id/btn_negative_custom_dialog"
                android:layout_width="0dp"
                android:layout_height="wrap_content"
                android:layout_weight="1"
                android:background="@android:color/transparent"
                android:text="取消"
                android:textColor="@android:color/holo_blue_dark" />

            <View
                android:layout_width="0.5dp"
                android:layout_height="match_parent"
                android:background="#dfdfdf" />

            <Button
                android:id="@+id/btn_positive_custom_dialog"
                android:layout_width="0dp"
                android:layout_height="wrap_content"
                android:layout_weight="1"
                android:background="@android:color/transparent"
                android:text="確定"
                android:textColor="@android:color/holo_blue_dark" />
        </LinearLayout>
    </LinearLayout>
</LinearLayout>

2、集成dialog重寫了一下

package newair.com.storelibrary.ui.custom.widget;

import android.app.Dialog;
import android.content.Context;
import android.content.DialogInterface;
import android.graphics.Color;
import android.graphics.drawable.ColorDrawable;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.view.Window;
import android.view.WindowManager;
import android.widget.Button;
import android.widget.FrameLayout;
import android.widget.LinearLayout;
import android.widget.TextView;

import newair.com.storelibrary.R;

/**

 */
public class CustomDialog extends Dialog {


    public CustomDialog(Context context) {
        super(context);
    }

    public CustomDialog(Context context, int themeResId) {
        super(context, themeResId);
    }

    protected CustomDialog(Context context, boolean cancelable, OnCancelListener cancelListener) {
        super(context, cancelable, cancelListener);
    }

    public static class Builder {
        private Context context;
        private String title;  //標題
        private String message;//提示消息
        private String negative_text;//消極的
        private String positive_text;//積極的
        private DialogInterface.OnClickListener negativeListener;//消極的監聽
        private DialogInterface.OnClickListener positiveListener;//積極的監聽

        public Builder(Context context) {
            this.context = context;
        }

        public Builder setTitle(String title) {
            if (title == null) {
                this.title = "提醒";
            }
            this.title = title;
            return this;
        }

        public Builder setMessage(String message) {
            if (message == null) {
                this.message = "您沒有填寫提示信息哦";
            }
            this.message = message;
            return this;
        }

        public Builder setNegativeButton(String negative_text, DialogInterface.OnClickListener negativeListener) {
            if (negative_text == null) {
                this.negative_text = "取消";
            }
            this.negative_text = negative_text;
            this.negativeListener = negativeListener;

            return this;
        }

        public Builder setPositionButton(String positive_text, DialogInterface.OnClickListener positiveListener) {
            if (positive_text == null) {
                this.positive_text = "確定";
            }
            this.positive_text = positive_text;
            this.positiveListener = positiveListener;

            return this;
        }

        private TextView tv_title_custom_dialog;  //標題
        private TextView tv_message_custom_dialog;//提示信息
        private Button btn_negative_custom_dialog;//消極
        private Button btn_positive_custom_dialog;//積極


        public CustomDialog create() {
            final CustomDialog dialog = new CustomDialog(context);
            View view = LayoutInflater.from(context).inflate(R.layout.dialog_custom_style_layout, null);
            dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);//加上這一句，取消原來的標題欄，沒加這句之前，發現在三星的手機上會有一條藍色的線
//            dialog.addContentView(view, new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT));
            dialog.setContentView(view, new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT));
            tv_title_custom_dialog = (TextView) view.findViewById(R.id.tv_title_custom_dialog);
            tv_message_custom_dialog = (TextView) view.findViewById(R.id.tv_message_custom_dialog);
            btn_negative_custom_dialog = (Button) view.findViewById(R.id.btn_negative_custom_dialog);
            btn_positive_custom_dialog = (Button) view.findViewById(R.id.btn_positive_custom_dialog);
            tv_title_custom_dialog.setText(title);
            tv_message_custom_dialog.setText(message);
            btn_negative_custom_dialog.setText(negative_text);
            btn_positive_custom_dialog.setText(positive_text);
            dialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
            btn_negative_custom_dialog.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    negativeListener.onClick(dialog, Dialog.BUTTON_NEGATIVE);
                }
            });
            btn_positive_custom_dialog.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    positiveListener.onClick(dialog, Dialog.BUTTON_POSITIVE);
                }
            });
            return dialog;
        }
    }
}

3、使用起來和系統的用法一樣

CustomDialog.Builder builder = new CustomDialog.Builder(this);
                builder.setTitle("購物提醒")
                        .setMessage("我是提示信息，大家好好")
                        .setNegativeButton("再看看", new DialogInterface.OnClickListener() {
                            @Override
                            public void onClick(DialogInterface dialog, int which) {
                                dialog.dismiss();
                                Toast.makeText(GoodsListActivity.this, "點擊了取消按鈕", Toast.LENGTH_SHORT).show();
                            }
                        })
                        .setPositionButton("確定", new DialogInterface.OnClickListener() {
                            @Override
                            public void onClick(DialogInterface dialog, int which) {
                                dialog.dismiss();
                                Toast.makeText(GoodsListActivity.this, "點擊了確定按鈕", Toast.LENGTH_SHORT).show();
                            }
                        })
                        .create()
                        .show();
