Android自定义弹框样式
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:
