弹框样式的自定义是通过改变v7包下的AlertDialog的Window对象的view及控制Window的宽高实现的。所有源码如下，其中自定义View的宽度设置为手机屏幕宽度的82%。

使用方式如下：链式调用，可查看源码自己选择使用。

CustomDialog.Builder builder=new CustomDialog.Builder(mContext);
 builder.setTitle("自定义弹框")//默认为“提示”
  .setMessage("自定义内容")
  .setNegativeText("自定义取消文字")//默认为“取消”
  .setPositiveText("自定义确认文字")//默认为 “确认”
  .setOnPositiveButtonClickListener(new CustomDialog.OnPositiveButtonClickListener() {
  @Override
  public void onPositiveButtonClick(Dialog dialog) {
  ToastUtil.makeText(mContext,"自定义确认按钮监听逻辑处理");
  }
  })
  .setOnNegativeButtonClickListener(new CustomDialog.OnNegativeButtonClickListener() {
  @Override
  public void onNegativeButtonClick(Dialog dialog) {
  ToastUtil.makeText(mContext,"自定义取消按钮监听逻辑处理");
  }
  })
  .setCancelable(false)//默认true
  .build();

效果图如下，使用者可按照实际需要自定义xml文件进行更改：
