当我尝试加载屏幕时出现错误。它有一个相对布局，里面有一个表布局。该错误与屏幕膨胀有关，因此我认为这在某种程度上是相关的。

我的 XML:

除了通常的 OnCreate 和 onCreateOptionsMenu 之外，没有其他代码用于这些屏幕。当然，setContentView 设置为该屏幕。错误是这样的:

感谢您的帮助!

编辑:我正在添加该类的代码。就像我说的，它没有太多重要的代码，但也许你们可以看到一些我看不到的东西。

package com.example.domedroid;

import android.os.Bundle;
import android.view.Menu;

public class KernelInspectionScreen extends MainActivity{
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.kernel_inspection_screen);
    }

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

最佳答案

我认为问题来自于你使用字符串作为背景

android:background="@string/table_bg_color"

它应该是一个颜色对象。
