在验证后手动关闭AlertDialog

示例代码：

AlertDialog.Builder builder = new AlertDialog.Builder(this); builder.setTitle("提示"); builder.setMessage("请输入密码");

final EditText input = new EditText(this); input.setInputType(InputType.TYPE_CLASS_TEXT | InputType.TYPE_TEXT_VARIATION_PASSWORD); builder.setView(input);

builder.setPositiveButton("确定", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { String password = input.getText().toString(); if (TextUtils.isEmpty(password)) { Toast.makeText(MainActivity.this, "密码不能为空", Toast.LENGTH_SHORT).show(); } else { // 验证成功后手动关闭AlertDialog dialog.dismiss(); // 其他操作... } } });

builder.setNegativeButton("取消", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { dialog.dismiss(); } });

AlertDialog dialog = builder.create(); dialog.show();
