这两个android-support-v4.jar和android-support-v7-appcompat.jar文件出口。Eclipse 包括android-support-v4.jar默认情况下，当我尝试代码时：
// MainActivity.java
import android.support.v7.app.ActionBarActivity;// error
public class MainActivity extends ActionBarActivity {...} // error
// DisplayMessageActivity.java
import android.support.v4.app.NavUtils; // error on this line
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.display_message, menu);// error at R
return true;
}
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case android.R.id.home:
// This ID represents the Home or Up button. In the case of this
// activity, the Up button is shown. Use NavUtils to allow users
// to navigate up one level in the application structure. For

NavUtils.navigateUpFromSameTask(this);// error at NavUtils
return true;
}
return super.onOptionsItemSelected(item);
}

Replace one of the specified android-support-v4.jar with the other, so that you have the same one in both places. That will resolve your issue.
将指定的 android-support-v4.jar 中的一个替换为另一个，以便在两个位置都使用相同的一个。那将解决您的问题。
