最近需要做一个android自定义弹出框,在网上找了一下,看到了很多,于是就copy了一个。
添加了圆角的绘制,点击事件,适用新手,这个代码我也是在网上copy下来的,只是修改一下,话不多少上代码了

调用代码了
public void dialog(){
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();
Toast.makeText(getApplicationContext(), "点击了确认", Toast.LENGTH_SHORT).show();
//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();
Toast.makeText(getApplicationContext(), "点击了取消", Toast.LENGTH_SHORT).show();
}
});
builder.create().show();
}
//其实绘制圆角很简单<corners android:radius="5dp"/>,但是由于弹出框的布局效果,title、button的背景与背景不是一个控件,所以就分别画的
这个是圆角的绘制
//上面两个圆角的绘制
<?xml version="1.0" encoding="utf-8"?>

<!-- 设置填充颜色 为白色 -->
