在学习编写一个强制下线的代码,但是在AS上一直有错,代码和书上的都一样.

Question

package com.example.bestbroadcastpractice;
import android.content.DialogInterface;
import android.content.Intent;
import android.os.Bundle;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;

/**

  public class LoginActivity extends BaseActivity {
  private EditText accountEdit;
  private EditText passwordEdit;
  private Button login;
  @Override
  protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.login);
  accountEdit = (EditText) findViewById(R.id.account);
  passwordEdit = (EditText) findViewById(R.id.password);
  login = (Button) findViewById(R.id.login);
  login.setOnClickListener(new OnClickListener() {
  @Override
  public void onClick(View v)

          String account = accountEdit.getText().toString();
          String password = passwordEdit.getText().toString();
  

//如果账号是admin且密码是123456，就认为登录成功
if (account.equals("admin") && password.equals("123456"))
{
Intent intent = new Intent(LoginActivity.this, MainActivity.class);
startActivity(intent);
finish();
}
else {
Toast.makeText(LoginActivity.this, "account or password is invalid",
Toast.LENGTH_SHORT).show();
}
}
});
}
}

显示的login.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) 这里有错!

Answer 1

导入OnClickListener的路径：
import android.view.View.OnClickListener;
