Question

目前我的Java代码存在两个问题。

我在这里附上了代码。

基本上，它抱怨我试图解决的模糊方法调用，但似乎无法解决，而且显示B队的分数也存在问题。< / p>

帮助？这非常棘手，因为尽管代码完全相同，但我遇到了不同的问题。

package com.example.android.courtcounter;

import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.TextView;

public class MainActivity extends AppCompatActivity {

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

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.menu_main, menu);
    return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    // Handle action bar item clicks here. The action bar will
    // automatically handle clicks on the Home/Up button, so long
    // as you specify a parent activity in AndroidManifest.xml.
    int id = item.getItemId();

    //noinspection SimplifiableIfStatement
    if (id == R.id.action_settings) {
        return true;
    }

    return super.onOptionsItemSelected(item);
}

/**
 * Increase the score for Team A by 1 point.
 */
public void addOneForTeamA(View v) {
    displayForTeamA(1);
}

/**
 * Increase the score for Team A by 2 points.
 */
public void addTwoForTeamA(View v) {
    displayForTeamA(2);
}

/**
 * Increase the score for Team A by 3 points.
 */
public void addThreeForTeamA(View v) {
    displayForTeamA(3);
}

public void displayForTeamA(int score) {
    TextView scoreView = (TextView) findViewById(R.id.team_a_score);
    scoreView.setText(String.valueOf(score));
}

/**
 * Displays the given score for Team A.
 */
public void displayForTeamA(int score) {
    TextView scoreView = findViewById(R.id.team_a_score);
    scoreView.setText(String.valueOf(score));
}


/**
 * Increase the score for Team B by 1 point.
 */
public void addOneForTeamB(View v) {
    displayForTeamB(1);
}

/**
 * Increase the score for Team B by 2 points.
 */
public void addTwoForTeamB(View v) {
    displayForTeamB(2);
}

/**

    displayForTeamB(3);
}

/**

 */
public void displayForTeamA(int score) {
    TextView scoreView = findViewById(R.id.team_b_score);
    scoreView.setText(String.valueOf(score));
}
}

Answer 1

它抱怨暧昧的代码，因为你有三次写同样的方法：

public void displayForTeamA(int score) {
    TextView scoreView = (TextView) findViewById(R.id.team_a_score);
    scoreView.setText(String.valueOf(score));
}

/**
 * Displays the given score for Team A.
 */
public void displayForTeamA(int score) {
    TextView scoreView = findViewById(R.id.team_a_score);
    scoreView.setText(String.valueOf(score));
}

然后吼道：

/**
 * Displays the given score for Team B.
 */
public void displayForTeamA(int score) {
    TextView scoreView = findViewById(R.id.team_b_score);
    scoreView.setText(String.valueOf(score));
}

删除重复的定义。
