【Android】AlertDialog對話框

1.普通的：

AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);
            builder.setIcon(R.mipmap.ic_launcher);
            builder.setTitle("提醒：");
            builder.setMessage("確定刪除？");
            builder.setPositiveButton("確定", new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int i) {
                   //TODO
                }
            });
            builder.setNegativeButton("取消", new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int i) {
                    //TODO
                }
            });
            builder.setNeutralButton("忽略", new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int i) {
                    //TODO
                }
            });
            builder.show();

2. 列表：

AlertDialog.Builder 
            builder=new AlertDialog.Builder(MainActivity.this);
            builder.setIcon(R.mipmap.ic_launcher);
            builder.setTitle("選擇：");
            //    指定下拉列表的顯示數據
            final String[] day= {"星期一", "星期二", "星期三", "星期四", "星期五","星期六","星期日"};
            //    設置一個下拉的列表選擇項
            builder.setItems(day, new DialogInterface.OnClickListener()
            {
                @Override
                public void onClick(DialogInterface dialog, int i)
                {
                    Toast.makeText(MainActivity.this, "選擇的是：" + day[i], Toast.LENGTH_SHORT).show();
                }
            });
            builder.show();

3.包含單選框

AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);
            builder.setIcon(R.mipmap.ic_launcher);
            builder.setTitle("請選擇性別");
            final String[] sex = {"男", "女"};
            /**
             * 第一個參數：數據集合
             * 第二個參數：默認勾選
             * 第三個參數：綁定監聽器
             */
            builder.setSingleChoiceItems(sex, 1, new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int i) {
                    Toast.makeText(MainActivity.this, "性別：" + sex[i], Toast.LENGTH_SHORT).show();
                }
            });
            builder.setPositiveButton("確定", new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int i) {
                    //TODO
                }
            });
            builder.setNegativeButton("取消", new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int i) {
                    //TODO
                }
            });
            builder.show();

4.包含CheckBox

AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);
            builder.setIcon(R.mipmap.ic_launcher);
            builder.setTitle("水果");
            final String[] hobbies = {"蘋果", "香蕉", "菠蘿", "橘子"};
            //Boolean[] select={true,false,false,true};
            /**
             * 第一個參數：數據集合
             * 第二個參數:如果是null，則一個都不選擇，指定多個被選擇，則傳遞一個Boolean數組進去
             * 第三個參數：綁定監聽器
             */
            builder.setMultiChoiceItems(hobbies, null, new DialogInterface.OnMultiChoiceClickListener() {
                StringBuffer stringBuffer = new StringBuffer(100);
                @Override
                public void onClick(DialogInterface dialog, int i, boolean isChecked) {
                    if(isChecked) {
                        stringBuffer.append(hobbies[i] + ", ");
                    }
                    Toast.makeText(MainActivity.this, "愛好爲：" + stringBuffer.toString(), Toast.LENGTH_SHORT).show();
                }
            });
            builder.setPositiveButton("確定", new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int i) {
                    //TODO
                }
            });
            builder.setNegativeButton("取消", new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int i) {
                    //TODO
                }
            });
            builder.show();
