Android 文本视图可以'；t转换到小部件

我将holoeverywhere与我的应用程序中的viewpagerindicator相结合，但出现以下错误：

当我单击error时，它似乎在部分TextView title=（TextView）v.findViewById（R.id.title\u update）

如何修复它？

删除导入

import org.holoeverywhere.widget.TextView;

并将其替换为

import android.widget.TextView;

---

从外观上看，您在布局文件中使用的是标准的Android

TextView

，而不是自定义的

org.holoaverywhere.widget.TextView

<org.holoeverywhere.widget.TextView
    android:id="@+id/title_update"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" />

---

确保导入了org.holoeverywhere.widget.TextView，如下所示

import android.app.Activity;
import android.os.Bundle;
import org.holoeverywhere.widget.TextView;

public class MyActivity extends Activity {
/**
 * Called when the activity is first created.
 */

private TextView mTvShow;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    mTvShow = (TextView) this.findViewById(R.layout.main);
    mTvShow.setText("Hello");
  }
}


<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
          android:orientation="vertical"
          android:layout_width="fill_parent"
          android:layout_height="fill_parent">
<org.holoeverywhere.widget.TextView
        android:id="@+id/holo_tv_show"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="Hello World, MyActivity"/>
</LinearLayout>

导入android.app.Activity；
导入android.os.Bundle；
导入org.holoeverywhere.widget.TextView；
公共类MyActivity扩展了活动{
/**
*在首次创建活动时调用。
*/
私有文本视图mTvShow；
@凌驾
创建时的公共void（Bundle savedInstanceState）{
super.onCreate（savedInstanceState）；
setContentView（R.layout.main）；
mTvShow=（TextView）this.findviewbyd（R.layout.main）；
mTvShow.setText（“你好”）；
}
}
