【问题描述】：
我正在尝试在 Android Studio 中创建一个应用程序，该应用程序根据从一组 4 个搜索栏（每个 RGBA 值一个）收集的 RGBA 值更改框的颜色。
目前我已将其设置为每个搜索栏的数值实时显示在栏下方。
除了下面的文本之外，我还没有到达将条形连接到其他任何内容的部分。它就像一个魅力，直到我去添加一个 ImageButton 到组合中（通过设计视图），突然之间我不断收到以下错误：

现在我到处寻找解决方案，并在 StackOverflow 和其他一些网站上发现了几个类似的问题，但似乎没有任何效果。我不确定我的代码是否太庞大或什么。我检查了 android.view.InflateException: Binary XML file line #87" Error 中引用的 XML 文件，但那是在一个我什至没有接触过的自动生成的类中
这是在我的 content_main.xml 文件中给我带来麻烦的 TextView
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceSmall"
android:text="Small Text"
android:id="@+id/textViewAlphaProg"
android:layout_below="@+id/seekBarAlpha"
android:layout_centerHorizontal="true"
android:background="@color/abc_search_url_text"/>
这是我相当冗长的 MainActivity.java

text_view_red.setText("Red Value : " + seek_bar_red.getProgress() + " of " + seek_bar_red.getMax());
seek_bar_red.setOnSeekBarChangeListener(

}
public void seekbaralpha() {
//Alpha Value
seek_bar_alpha = (SeekBar) findViewById(R.id.seekBarAlpha);
text_view_alpha = (TextView) findViewById(R.id.textViewAlphaProg);
text_view_alpha.setText("Alpha Value : " + seek_bar_alpha.getProgress() + " of " +

@Override

progress_value_alpha = progress;
text_view_alpha.setText("Alpha Value : " + progress + " of " +
seek_bar_alpha.getMax());
//Toast.makeText(MainActivity.this, "SeekBar in Progress", Toast

}
@Override

}
@Override

Toast.makeText(MainActivity.this, "SeekBar in StopTracking", Toast
.LENGTH_LONG).show();*/
}
}
);
}
}
因此，如果有人知道我该如何解决这个问题，以便它可以再次运行，我可以继续编写代码，那将是非常棒的。如果有人对执行搜索栏功能的更简单方法有任何建议，那也很好。
