在Android中加载屏幕时出错
[英]Error loading a screen in Android
问题描述
当我尝试加载屏幕时，出现错误。 它具有相对布局，内部具有表格布局。 错误与屏幕膨胀有关，所以我认为这是相关的。

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

感谢您的任何帮助！
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;
}
}

我认为问题来自您使用String作为背景的事实
android：background =“ @ string / table_bg_color”
它应该是一个颜色对象。

按照我的看法，在查看您的日志错误的是这一行：
android:background="@string/table_bg_color"
尝试在所有地方使用此行：
android:background="#0f6f0f"
要么 ：
将XML文件保存在res / values / colors.xml：
<?xml version="1.0" encoding="utf-8"?>
<resources>
<color name="table_bg_color">#0f6f0f</color>
<color name="translucent_red">#80ff0000</color>
</resources>
然后像这样使用：
android:background="@color/table_bg_color"
谢谢。
