Question

当输入为milk时，我正在尝试获取提交按钮以转到下一页。这是我到目前为止所尝试的内容

package com.example.ephraimcohen.prestwichlanguageschool;

import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;

public class activitytwomilk2 extends AppCompatActivity {

    private EditText Word;
    private TextView TryAgain;
    private Button Submit;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_activitytwomilk2);

        Word = (EditText)findViewById(R.id.etword);
        TryAgain = (TextView)findViewById(R.id.tvtryagian);
        Submit = (Button) findViewById(R.id.btnsubmit);

        TryAgain.setText(" ");

        Submit.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                validate(Word.getText().toString());
            }
        });

    }

    private void validate(String userWord){
        if((userWord.equals ("milk"))){
            Intent intent = new Intent(activitytwomilk2.this, activitytwomilkcorrect.class);
            startActivity(intent);

        }else{

            TryAgain.setText(" " + "Try again");
            }
        }`

在此之下，还有另一个按钮可以进入主屏幕。该按钮工作正常并带我到主页。

尝试在您的情况下使用==而不是等于

    if(userWord=="milk"){
        Intent intent = new Intent(activitytwomilk2.this, activitytwomilkcorrect.class);
        startActivity(intent);
    }else{
        TryAgain.setText(" " + "Try again");
        }
    }`

提交按钮未验证
