自定义Dialog

AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("最新版本:" + mVersionName);
builder.setMessage(mDesc);
// builder.setCancelable(false);//不让用户取消对话框, 用户体验太差,尽量不要用
builder.setPositiveButton("立即更新", new OnClickListener() {

@Override
public void onClick(DialogInterface dialog, int which) {
System.out.println("立即更新");
download();
}
});

builder.setNegativeButton("以后再说", new OnClickListener() {

@Override

// 设置取消的监听, 用户点击返回键时会触发

builder.show();

AlertDialog.Builder setpw=new AlertDialog.Builder(this);

View adview=View.inflate(HomeActivity.this,R.layout.dialog_set_passwd,null);//创建一个View对象。布局是xml写好了的
setpwad.setView(adview,0,0,0,0);//设置布局，后的参数表示间距。

final EditText btpasswd=(EditText)adview.findViewById(R.id.editText);
final EditText btpasswdconfirm=(EditText)adview.findViewById(R.id.editText2);//找到布局内的组建

Button cancle=(Button)adview.findViewById(R.id.cancer);

}
