Android自定义Dialog(美化界面)-白红宇

前言:在做项目的时候,发现dialog界面太丑陋,从csdn上下载了一份自定义dialog的源码,在他的基础上对界面进行美化...有需要的朋友可以直接拿走

效果图如下：

主要代码:

            }  
            dialog.setContentView(layout);  
            return dialog;  
        }  
  
    }  
}  

4.Activity中如何调用:

CustomDialog.Builder builder = new CustomDialog.Builder(this);  
builder.setMessage("这个就是自定义的提示框");  
builder.setTitle("提示");  
builder.setPositiveButton("确定", new DialogInterface.OnClickListener() {  
    public void onClick(DialogInterface dialog, int which) {  
        dialog.dismiss();  
        //设置你的操作事项  
    }  
});  
  
builder.setNegativeButton("取消",  
        new android.content.DialogInterface.OnClickListener() {  
            public void onClick(DialogInterface dialog, int which) {  
                dialog.dismiss();  
            }  
        });  
  
builder.create().show();
