安卓仿qq侧滑

公司要做一侧滑菜单，和QQ类似的侧滑菜单效果。利用DrawerLayout实现效果比较好。实现比较简单。


drawerLayout.setDrawerListener(new DrawerListener() {
			@Override
			public void onDrawerStateChanged(int newState) {
			}
 
			@Override
			public void onDrawerSlide(View drawerView, float slideOffset) {
				View mContent = drawerLayout.getChildAt(0);
				View mMenu = drawerView;
				float scale = 1 - slideOffset;
				float rightScale = 0.8f + scale * 0.2f;
 
				if (drawerView.getTag().equals("LEFT")) {
 
					float leftScale = 1 - 0.3f * scale;
 
					ViewHelper.setScaleX(mMenu, leftScale);
					ViewHelper.setScaleY(mMenu, leftScale);
					ViewHelper.setAlpha(mMenu, 0.6f + 0.4f * (1 - scale));
					ViewHelper.setTranslationX(mContent, mMenu.getMeasuredWidth() * (1 - scale));
					ViewHelper.setPivotX(mContent, 0);
					ViewHelper.setPivotY(mContent, mContent.getMeasuredHeight() / 2);
					mContent.invalidate();
					ViewHelper.setScaleX(mContent, rightScale);
					ViewHelper.setScaleY(mContent, rightScale);
				} else {
					ViewHelper.setTranslationX(mContent, -mMenu.getMeasuredWidth() * slideOffset);
					ViewHelper.setPivotX(mContent, mContent.getMeasuredWidth());
					ViewHelper.setPivotY(mContent, mContent.getMeasuredHeight() / 2);
					mContent.invalidate();
					ViewHelper.setScaleX(mContent, rightScale);
					ViewHelper.setScaleY(mContent, rightScale);
				}
 
			}
 
			@Override
			public void onDrawerOpened(View drawerView) {
			}
 
			@Override
			public void onDrawerClosed(View drawerView) {
				drawerLayout.setDrawerLockMode(DrawerLayout.LOCK_MODE_LOCKED_CLOSED, Gravity.RIGHT);
			}
		});

布局代码：

<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/id_drawerLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@drawable/sidebar_bg" >

<LinearLayout
android:id="@+id/id_center_linear"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal"
>
</LinearLayout>

<LinearLayout
android:id="@+id/id_left_menu"
android:layout_width="250dp"
android:layout_height="match_parent"
android:layout_gravity="left"
android:orientation="horizontal"
android:tag="LEFT"
>
</LinearLayout>
</android.support.v4.widget.DrawerLayout>
