错误膨胀class material.bottomnavigation.BottomNavigationView

问题描述 投票：1回答：2

我正在尝试实现BottomNavigationView，我知道关于同一问题有多个答案，但是似乎没有一个对我有用。

我关注了此doc

在预览模式下，出现此错误

IllegalArgumentException: Unknown color

当我运行TestActivity时，出现使类膨胀的错误

  • 可绘制图形在可绘制图形
    • 中
  • 菜单在res / menu]内部>

    • 对于我从不同帖子中的答案所能理解的是资源问题。

我试图删除每个资源调用，但是即使仅定义了宽度和高度，我仍然会收到错误。

TestActivity

import android.os.Bundle;
import androidx.appcompat.app.AppCompatActivity;

public class TestActivity extends AppCompatActivity {

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

在BottomNavigationView中，由于XML会发生膨胀错误，它可能在@layout，@drawable，@style或@color文件夹中。
