Java代码 new AlertDialog.Builder(activity) .setView(view) .setCancelable(false) .setTitle("登陆系统") .setPositiveButton("登录", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int i) { EditText userName = (EditText) view.findViewById(R.id.editText); EditText userpwd = (EditText) view.findViewById(R.id.editText1); try { if (userName == null || userName.getText().toString().trim().length() == 0) { //不关闭对话框 Field field = dialog.getClass().getSuperclass().getDeclaredField("mShowing"); field.setAccessible(true); field.set(dialog, false); //设定为false,则不可以关闭对话框 dialog.dismiss(); ToastUtils.show(activity, "没有输入用户名......"); } else if (userpwd == null || userpwd.getText().toString().trim().length() == 0) { //不关闭对话框 Field field = dialog.getClass().getSuperclass().getDeclaredField("mShowing"); field.setAccessible(true); field.set(dialog, false); //设定为false,则不可以关闭对话框 dialog.dismiss(); ToastUtils.show(activity, "没有输入密码......"); } else { // 要正常关闭对话框 ToastUtils.show(activity, "登陆成功......"); Field field = dialog.getClass().getSuperclass().getDeclaredField("mShowing"); field.setAccessible(true); field.set(dialog, true);//设定为true,则可以关闭对话框 dialog.dismiss(); } } catch (Exception e) { } } }) .setNegativeButton("取消", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialogInterface, int i) { activity.finish(); } } ) .create() .show(); |
可以关闭：
field.setAccessible(true);
field.set(dialog, true);//设定为true,则可以关闭对话框/color]
禁止关闭：
[color=darkblue]field.setAccessible(true);
field.set(dialog, false); //设定为false,则不可以关闭对话框
