Android实战Android沉浸式状态栏实现（下）

贵有恒，何必三更起、五更眠、最无益，只怕一日曝、十日寒。这篇文章主要讲述Android实战Android沉浸式状态栏实现（下）相关的知识，希望能为你提供帮助。
之前的Android沉浸式状态栏实现并没有考虑软键盘的影响，接下来的内容将会针对这个问题给出解决方式，先看一下效果图
这个是一个留言板的效果图：

即弹出软键盘的时候并不会导致整个布局上移。
详细怎样实现？依照下面步骤进行设置：
1、布局文件里声明例如以下

< activity android:name="com.storm.durian.activity.LeaveMessageDetailsActivity" android:screenOrientation="portrait" />

2、这里重写了RelativeLayout。并重写了fitSystemWindows，这个是最最关键的。

/** * 自适应布局 */ public class FitsSystemWindowsLayout extends RelativeLayout { private static final String TAG = FitsSystemWindowsLayout.class.getSimpleName(); private SoftKeyBoardStateListener softKeyBoardStateListener; public FitsSystemWindowsLayout(Context context) { super(context); }public FitsSystemWindowsLayout(Context context, AttributeSet attrs) { super(context, attrs); }public FitsSystemWindowsLayout(Context context, AttributeSet attrs, int defStyle) { super(context, attrs, defStyle); }@Override protected void onMeasure(final int widthMeasureSpec, final int heightMeasureSpec) {dispatchListenerLow(heightMeasureSpec); super.onMeasure(widthMeasureSpec, heightMeasureSpec); }/** * 处理低版本号键盘弹出 * * @param heightMeasureSpec 高度 */ private void dispatchListenerLow(int heightMeasureSpec) { if (softKeyBoardStateListener == null || Build.VERSION.SDK_INT > = Build.VERSION_CODES.KITKAT) { return; } int oldSpec = getMeasuredHeight(); if (oldSpec < = 0) { return; } int newSpec = MeasureSpec.getSize(heightMeasureSpec); int offset = oldSpec - newSpec; if (offset > 100) { LogHelper.i(TAG, "键盘打开"); softKeyBoardStateListener.onSoftKeyBoardStateChange(true); } else if (offset < -100) { LogHelper.i(TAG, "键盘关闭"); softKeyBoardStateListener.onSoftKeyBoardStateChange(false); } }@Override protected boolean fitSystemWindows(Rect insets) { dispatchListener(insets); insets.top = 0; return super.fitSystemWindows(insets); }/** * 分发监听 * * @param insets */ private void dispatchListener(Rect insets) { if (softKeyBoardStateListener == null || android.os.Build.VERSION.SDK_INT < Build.VERSION_CODES.KITKAT) { return; } if (insets.top != 0 & & insets.bottom != 0) { LogHelper.i(TAG, "键盘打开"); softKeyBoardStateListener.onSoftKeyBoardStateChange(true); } else { LogHelper.i(TAG, "键盘关闭"); softKeyBoardStateListener.onSoftKeyBoardStateChange(false); }}/** * 设置软键盘监听事件 * * @param softKeyBoardStateListener */ public void setSoftKeyBoardListener(SoftKeyBoardStateListener softKeyBoardStateListener) { this.softKeyBoardStateListener = softKeyBoardStateListener; }public interface SoftKeyBoardStateListener {public void onSoftKeyBoardStateChange(boolean isOpen); } }

【Android实战Android沉浸式状态栏实现（下）】尽管以上布局也提供了键盘打开或者关闭的回调，可是在某些低版本号手机上还是支持的不太好，须要这个回调的能够将此回调作为当中一个方法。可是不要过分依赖
3、布局文件使用com.storm.durian.view.FitsSystemWindowsLayout包裹整个布局，并设置android:fitsSystemWindows=“true”

< ?xml version="1.0" encoding="utf-8"?
> < com.storm.durian.view.FitsSystemWindowsLayout android:id="@+id/leave_message_layout" xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:background="@color/ececec" android:fitsSystemWindows="true"> < include android:id="@+id/leave_message_title" layout="@layout/common_back"/> < LinearLayout android:id="@+id/ll_leave_message_input" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_alignParentBottom="true" android:background="@drawable/leave_message_bottom_bg" android:orientation="horizontal"> < EditText android:id="@+id/et_leave_message" android:layout_width="0dp" android:layout_height="wrap_content" android:layout_weight="3" android:background="@drawable/et_leave_message_bg" android:hint="亲，给我留言我会回复你哒~" android:maxLines="4" android:textColor="@color/_3e363d" android:textSize="@dimen/text_size_small"/> < Button android:id="@+id/btn_leave_message_send" android:layout_width="0dp" android:layout_height="wrap_content" android:layout_marginLeft="10dp" android:layout_weight="1" android:background="@drawable/btn_leave_message_send_selector" android:singleLine="true" android:text="发送" android:textColor="@color/_3e363d" android:textSize="@dimen/text_size_middle"/> < /LinearLayout> < ListView android:id="@+id/lv_leave_message" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_above="@id/ll_leave_message_input" android:layout_below="@id/leave_message_title" android:cacheColorHint="#00000000" android:divider="@color/dbdbdb" android:dividerHeight="1dp" android:fadingEdge="none"/> < ViewStub android:id="@+id/activity_leave_message_loading_stub" android:layout_width="match_parent" android:layout_height="match_parent" android:layout_below="@id/leave_message_title" android:inflatedId="@+id/activity_leave_message_loading_subTree" android:layout="@layout/common_loading"/> < ViewStub android:id="@+id/leave_message_empty_stub" android:layout_width="match_parent" android:layout_height="match_parent" android:layout_above="@id/ll_leave_message_input" android:layout_below="@id/leave_message_title" android:inflatedId="@+id/leave_message_empty_subTree" android:layout="@layout/common_tips_layout"/> < ViewStub android:id="@+id/leave_message_net_error_stub" android:layout_width="match_parent" android:layout_height="match_parent" android:layout_below="@id/leave_message_title" android:inflatedId="@+id/leave_message_net_error_subTree" android:layout="@layout/common_net_error_layout"/> < /com.storm.durian.view.FitsSystemWindowsLayout>

4、Activity中处理
设置setImmerseLayout(findViewById(R.id.leave_message_title));

@Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_leave_detail_message); setImmerseLayout(findViewById(R.id.leave_message_title)); logic = LeaveMessageLogic.getInstance(getApplicationContext()); mHandler = new MyHandler(this); initView(); }

再看BaseActivity中的setImmerseLayout方法
版本号要求仍然是4.4以上

@Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); isStart = true; ShareSDK.initSDK(this); if (Build.VERSION.SDK_INT > = Build.VERSION_CODES.KITKAT) { //透明状态栏 getWindow().addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS); //透明导航栏 //getWindow().addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION); statusBarHeight = ScreenUtil.getStatusBarHeight(this); } ScreenManager.getScreenManager().pushActivity(this); }

protected void setImmerseLayout(View view) { if (Build.VERSION.SDK_INT > = Build.VERSION_CODES.KITKAT) { Window window = getWindow(); window.setFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS, WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS); // window.addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS); int statusBarHeight = ScreenUtil.getStatusBarHeight(this.getBaseContext()); view.setPadding(0, statusBarHeight, 0, 0); } }

OK。须要的朋友们能够自己尝试一下！
有空的话会将这个沉浸式的留言板的功能写一下分享出来！
