如何在Android中利用Dialog实现一个对话框功能

AlertDialog.Builder builder = new AlertDialog.Builder(activity);
builder.setTitle("温馨提示");//标题
builder.setMessage("天气冷，注意保暖");
builder.setIcon(R.mipmap.ic_launcher);
builder.create();
builder.show();

builder.setTitle("确定取消对话框");
builder.setMessage("请选择确定或取消");
builder.setIcon(R.mipmap.ic_launcher);

 //正能量按钮 Positive
 @Override
 public void onClick(DialogInterface dialog, int which) {
 Toast.makeText(activity, "你点击了确定", Toast.LENGTH_SHORT).show();
 }
});
builder.setNegativeButton("取消", new DialogInterface.OnClickListener() {
 @Override
 public void onClick(DialogInterface dialog, int which) {
 Toast.makeText(activity, "你选择了取消", Toast.LENGTH_SHORT).show();
 }
});
builder.create().show();
