Question

我正在通过遵循库https://github.com/aurelhubert/ahbottomnavigation使用底部导航栏来开发cv应用程序，但是当我运行代码时，却遇到了错误

E/AndroidRuntime: FATAL EXCEPTION: main
    Process: activity.drawer.navigation.com.kitabsawticlone, PID: 21292
    java.lang.ArrayIndexOutOfBoundsException: length=5; index=5

在实现底部导航栏的代码下方

import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;    
import com.aurelhubert.ahbottomnavigation.AHBottomNavigation;
import com.aurelhubert.ahbottomnavigation.AHBottomNavigationAdapter;
import com.aurelhubert.ahbottomnavigation.AHBottomNavigationItem;


public class MainActivity extends AppCompatActivity {
    private AHBottomNavigationAdapter navigationAdapter;
  private AHBottomNavigation bottomNavigation;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        bottomNavigation = findViewById(R.id.bottom_navigation);


        AHBottomNavigation bottomNavigation = (AHBottomNavigation) findViewById(R.id.bottom_navigation);
        int[] tabColors = getApplicationContext().getResources().getIntArray(R.array.tab_colors);
        AHBottomNavigationAdapter navigationAdapter = new AHBottomNavigationAdapter(this, R.menu.bottom_navigation_menu);
        navigationAdapter.setupWithBottomNavigation(bottomNavigation, tabColors);
// Create items
        AHBottomNavigationItem item1 = new AHBottomNavigationItem(R.string.text_introduction, R.drawable.ic_introduction, R.color.color_tab_1);
        AHBottomNavigationItem item2 = new AHBottomNavigationItem(R.string.text_education, R.drawable.ic_education, R.color.color_tab_2);
        AHBottomNavigationItem item3 = new AHBottomNavigationItem(R.string.text_work, R.drawable.ic_work, R.color.color_tab_3);
        AHBottomNavigationItem item4 = new AHBottomNavigationItem(R.string.text_skills, R.drawable.ic_skills, R.color.color_tab_4);
        AHBottomNavigationItem item5 = new AHBottomNavigationItem(R.string.text_contact, R.drawable.ic_contact, R.color.color_tab_5);



        bottomNavigation.addItem(item1);
        bottomNavigation.addItem(item2);
        bottomNavigation.addItem(item3);
        bottomNavigation.addItem(item4);
        bottomNavigation.addItem(item5);

    }
}

Answer 1

检查R.array.tab_colors中有多少个项目。

Answer 2

请这样替换您的代码，然后检查

import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;

import com.aurelhubert.ahbottomnavigation.AHBottomNavigation;
import com.aurelhubert.ahbottomnavigation.AHBottomNavigationAdapter;
import com.aurelhubert.ahbottomnavigation.AHBottomNavigationItem;


public class MainActivity extends AppCompatActivity {
    private AHBottomNavigationAdapter navigationAdapter;
  private AHBottomNavigation bottomNavigation;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        bottomNavigation = findViewById(R.id.bottom_navigation);     

// Create items
        AHBottomNavigationItem item1 = new AHBottomNavigationItem(R.string.text_introduction, R.drawable.ic_introduction, R.color.color_tab_1);
        AHBottomNavigationItem item2 = new AHBottomNavigationItem(R.string.text_education, R.drawable.ic_education, R.color.color_tab_2);
        AHBottomNavigationItem item3 = new AHBottomNavigationItem(R.string.text_work, R.drawable.ic_work, R.color.color_tab_3);
        AHBottomNavigationItem item4 = new AHBottomNavigationItem(R.string.text_skills, R.drawable.ic_skills, R.color.color_tab_4);
        AHBottomNavigationItem item5 = new AHBottomNavigationItem(R.string.text_contact, R.drawable.ic_contact, R.color.color_tab_5);
        bottomNavigation.addItem(item1);
        bottomNavigation.addItem(item2);
        bottomNavigation.addItem(item3);
        bottomNavigation.addItem(item4);
        bottomNavigation.addItem(item5);

           int[] tabColors = getApplicationContext().getResources().getIntArray(R.array.tab_colors);
        AHBottomNavigationAdapter navigationAdapter = new AHBottomNavigationAdapter(this, R.menu.bottom_navigation_menu);
        navigationAdapter.setupWithBottomNavigation(bottomNavigation, tabColors);



    }
}

我正在获取E / AndroidRuntime：致命异常：main java.lang.ArrayIndexOutOfBoundsException：length = 5;指数= 5
