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：
