很多項目都用到類似左側滑動菜單的效果,比如facebook,evernote,VLC for android等等,這很酷
原始碼可以從GitHub的https://github.com/jfeinstein10/slidingmenu上下載。
移植過程中會用到Actionbarsherlock這個項目,去http://actionbarsherlock.com/download.html下載。(兩個下的都是最新版本)
步驟:
1.將下載的Actionbarssherlock中/library下的檔案解壓到workspace(你的項目目錄),改項目名稱為Actionbarssherlock,從eclipse中操作new->project->Android Project from Existing Code將項目添加進去,target改為api14以上。
2.將下載的slidingmenu中/library解壓到workspace(你的項目目錄),改名SlidingMenu,import該項目,右鍵->properties->android->api14以上。或者開啟project.properties:target=Google Inc.:Google APIs:14或更高。
3.這樣SlidingMenu就可以用在自己項目中了。讓我們來運行例子。解壓slidingmenu中/example。import該項目,設定api14或更高,並add你的SlidingMenu。運行看看效果。2.1以上的系統都可以運行。
雖然是開源項目,但使用過程中還是可能會出現各種問題:
一、修複SlidingMenu library project裡出現的錯誤
Console error: Unable to resolve target ‘Google Inc.:Google APIs:16.
Fix: 進入Properties檢查Target sdk是否選擇了 Google APIs.
List of errors: ACTION_POINTER_INDEX_MASK cannot be resolved android.
HONEYCOMB cannot be resolved or is not a field
LAYER_TYPE_HARDWARE cannot be resolved or is not a field
LAYER_TYPE_NONE cannot be resolved or is not a field
MATCH_PARENT cannot be resolved or is not a field
The method getLayerType() is undefined for the type View
The method setLayerType(int, null) is undefined for the type View
Fix: 將manifest裡面的min sdk version 改為你當前用到的sdk版本,7以上.
二、修複example project裡出現的錯誤
Console error: Found 2 versions of android-support-v4.jar in the dependency list,but not all the versions are identical (check is based on SHA-1 only at this time). Jar mismatch! Fix your dependencies
Fix: 這是由於jar包版本不一致導致的,檢查SlidingMenu和Actionbarsherlock中的\libs檔案夾裡的哪個android-support-v4.jar版本比較新,用新的替換掉其中的老版本. 如果錯誤還是會出現,就clean項目並重啟eclipse.
List of errors: The method getSupportActionBar() is undefined for the type BaseActivity
The method getSupportMenuInflater() is undefined for the type BaseActivity
The method onCreateOptionsMenu(Menu) of type BaseActivity must override or implement a supertype method
The method onOptionsItemSelected(MenuItem) in the type Activity is not applicable for the arguments
The method onOptionsItemSelected(MenuItem) of type BaseActivity must override or implement a supertype method
The method onOptionsItemSelected(MenuItem) of type ResponsiveUIActivity must override or implement a supertype method
Fix:開啟SlidingMenu library project裡SlidingFragmentActivity這個類並在聲明前添加以下代碼:
[java] view plaincopy
- import com.actionbarsherlock.app.SherlockFragmentActivity;
然後,將下面這個父類:
[java] view plaincopy
- public class SlidingFragmentActivity extends FragmentActivity implements SlidingActivityBase {
換成Actionbarsherlock裡的另外一個父類:
[java] view plaincopy
- public class SlidingFragmentActivity extends SherlockFragmentActivity implements SlidingActivityBase {
如果錯誤還是會出現,就clean項目並重啟eclipse.
沒錯誤以後運行出下面效果:
移植SlidingMenu Android library,和安裝example出現的問題解決
