自定義彈框樣式

彈框樣式的自定義是通過改變v7包下的AlertDialog的Window對象的view及控制Window的寬高實作的。所有源碼如下，其中自定義View的寬度設定為手機螢幕寬度的82%。

使用方式如下：鍊式調用，可檢視源碼自己選擇使用。

CustomDialog.Builder builder=new CustomDialog.Builder(mContext);
                builder.setTitle("自定義彈框")//預設為“提示”
                        .setMessage("自定義内容")
                        .setNegativeText("自定義取消文字")//預設為“取消”
                        .setPositiveText("自定義确認文字")//預設為 “确認”
                        .setOnPositiveButtonClickListener(new CustomDialog.OnPositiveButtonClickListener() {
                            @Override
                            public void onPositiveButtonClick(Dialog dialog) {
                                ToastUtil.makeText(mContext,"自定義确認按鈕監聽邏輯處理");
                            }
                        })
                        .setOnNegativeButtonClickListener(new CustomDialog.OnNegativeButtonClickListener() {
                            @Override
                            public void onNegativeButtonClick(Dialog dialog) {
                                ToastUtil.makeText(mContext,"自定義取消按鈕監聽邏輯處理");
                            }
                        })
                        .setCancelable(false)//預設true
                        .build();

效果圖如下，使用者可按照實際需要自定義xml檔案進行更改：
