text
Body
copied!<p><strong>Dears,</strong> </p> <p>I'm new to Android, and try to use SlidingMenu in my project. I want to create an application with two sliding menus same as Facebook.</p> <p>With these steps I had crated my application: </p> <ol> <li>Download and add SlidingMenu library into my work-space. </li> <li>Download and add actionbarsherlock library to my work-space.</li> <li>In SlidingMenu library I add actionbarsherlock as a reference library. </li> <li>In SlidingMenu library, I extend <code>SlidingActivity.java</code> with actionbarsherlock: <code>public class SlidingActivity extends SherlockActivity implements SlidingActivityBase</code></li> <li>In my application, I add reference to SlidingMenu library.</li> <li>In my application, I extend my main activity to use <code>SlidingActivity</code> : <code>public class MainMenu extends SlidingActivity</code></li> </ol> <p><strong>My main activity code:</strong></p> <pre><code>import android.app.ActionBar; import android.os.Bundle; import android.view.KeyEvent; import com.actionbarsherlock.view.MenuInflater; import com.jeremyfeinstein.slidingmenu.lib.SlidingMenu; import com.jeremyfeinstein.slidingmenu.lib.app.SlidingActivity; public class MainMenu extends SlidingActivity { SlidingMenu menu; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); if (enableHomeIconActionBack() || enableHomeIconActionSlidingMenu()) { ActionBar actionBar = getActionBar(); if (actionBar != null){ actionBar.setDisplayHomeAsUpEnabled(true); } } setContentView(R.layout.activity_main_menu); setBehindContentView(R.layout.activity_main_menu); menu = new SlidingMenu(this); menu.setTouchModeAbove(SlidingMenu.TOUCHMODE_FULLSCREEN); menu.setMode(SlidingMenu.LEFT_RIGHT); menu.setShadowWidthRes(R.dimen.sliding_menu_shadow_width); menu.setShadowDrawable(R.drawable.shadow); menu.setBehindOffsetRes(R.dimen.sliding_menu_offset); menu.setFadeDegree(0.35f); menu.attachToActivity(this, SlidingMenu.SLIDING_WINDOW); menu.setMenu(R.layout.sliding_menu_frame); menu.setSecondaryMenu(R.layout.vehicles_tree); menu.setSecondaryShadowDrawable(R.drawable.shadow); } @Override public boolean onCreateOptionsMenu(com.actionbarsherlock.view.Menu menu) { // Inflate the menu; this adds items to the action bar if it is present. MenuInflater inflater = getSupportMenuInflater(); inflater.inflate(R.menu.main_menu, menu); return true; } @Override public boolean onOptionsItemSelected(com.actionbarsherlock.view.MenuItem item) { switch (item.getItemId()) { case android.R.id.home: if (enableHomeIconActionSlidingMenu() && menu != null) { menu.toggle(); } else if (enableHomeIconActionBack()) { onCustomBackPressed(); } return true; default: return super.onOptionsItemSelected(item); } } @Override public boolean onKeyDown(int keyCode, KeyEvent event) { switch (keyCode) { case KeyEvent.KEYCODE_BACK: onCustomBackPressed(); return true; default: return super.onKeyDown(keyCode, event); } } // If sliding menu is showing, we need to hide it on the first back button // press. private void onCustomBackPressed() { if (menu != null && menu.isMenuShowing()) { menu.toggle(); } else { this.onBackPressed(); } } /** * Sets activity home icon to have up icon and on press act as device back * button press. * * @return Activation state. */ public boolean enableHomeIconActionBack() { return true; } /** * Sets activity home icon to be as a sliding menu invoke icon and on press * call toggle command for the sliding menu. * * @return Activation state. */ public boolean enableHomeIconActionSlidingMenu() { return true; } } </code></pre> <p>Now, <code>menu.setMenu(R.layout.sliding_menu_frame);</code> will show: </p> <pre><code><?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:background="#FFFF00FF" > </RelativeLayout> </code></pre> <p>And <code>menu.setSecondaryMenu(R.layout.vehicles_tree);</code> will show: </p> <pre><code><?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:background="#FF0F00FF"> </RelativeLayout> </code></pre> <p><strong>The following snapshots describe the strange behavior:</strong> </p> <p><a href="http://img27.imageshack.us/img27/4166/47ry.jpg" rel="nofollow">Click to show image</a></p> <ol> <li>Main activity. </li> <li>When you swipe <strong>right</strong> on the <strong>screen</strong>.</li> <li>When you swipe <strong>left</strong> on the <strong>screen</strong>. </li> <li>When you swipe <strong>right</strong> from <strong>left screen edge</strong>. This activity covers the entire screen and it is showing the activity attached to <code>setBehindContentView(R.layout.activity_main_menu);</code>, I noticed that by changing the attached layout. </li> </ol> <p>I don't want the forth screen, what I'm doing wrong? </p> <p>Regards,, Ali Alaswad</p>
