我使用Jeremy Feinstein库实现了Sliding菜单。 哪个在Android版本上运行得非常好：4.x.x
但是当我尝试在Android版本2.3.x上执行时，应用程序崩溃并出现以下错误。

如何使其适用于Android版本：2.3.x。

答案 0 :(得分：0)
尝试使用以下代码。这就是我做到的，它对我有用。希望这段代码可以帮助你。
package com.example.calculators;
import android.os.Bundle;
import android.view.Menu;
import com.jeremyfeinstein.slidingmenu.lib.SlidingMenu;
import com.jeremyfeinstein.slidingmenu.lib.app.SlidingFragmentActivity;
public class MainActivity extends SlidingFragmentActivity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
setBehindContentView(R.layout.slidingmenu);
getSlidingMenu().setMode(SlidingMenu.LEFT);
getSlidingMenu().setTouchModeAbove(SlidingMenu.TOUCHMODE_FULLSCREEN);
getSlidingMenu().setFadeDegree(0.35f);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}
这是我的slidingmenu.xml
<?xml version="1.0" encoding="utf-8"?>
<fragment xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/fragback"
android:name="com.example.calculators.ListFrag"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
