隨手記-融雲 聊天界面標題欄被頂上去 解決方法

原創 alwaysGoalong 2018-08-23 00:05

由於我用了沉浸式狀態欄，導致在Androidmanifest中這樣設置（融雲的聊天界面通常設置）鍵盤遮蓋了輸入框

        <activity
            android:name=".ui.activity.ConversationActivity"
            android:configChanges="orientation|screenSize"
            android:screenOrientation="portrait"
                          android:windowSoftInputMode="stateHidden|adjustResize">

            <intent-filter>
                <action android:name="android.intent.action.VIEW" />

                <category android:name="android.intent.category.DEFAULT" />

                <data
                    android:host="包名"
                    android:pathPrefix="/conversation/"
                    android:scheme="rong" />
            </intent-filter>
        </activity>

但是如果使用
android:windowSoftInputMode="stateHidden|adjustPan"
又會導致標題欄被頂到界面以外，剛開始不知道是由於沉浸式狀態欄引起的，感覺融雲這麼弄挺蠢的，後來發現是自己挺蠢的。

解決方法：仍使用沉浸式狀態欄（直接設置了狀態欄的顏色），在聊天界面的根佈局添加android:fitsSystemWindows="true"
想了想還是貼上具體代碼，以備後用

Androidmanifest：

<activity
            android:name=".ui.activity.ConversationActivity"
            android:configChanges="orientation|screenSize"
            android:screenOrientation="portrait"
                          android:windowSoftInputMode="stateHidden|adjustResize">

            <intent-filter>
                <action android:name="android.intent.action.VIEW" />

                <category android:name="android.intent.category.DEFAULT" />

                <data
                    android:host="包名"
                    android:pathPrefix="/conversation/"
                    android:scheme="rong" />
            </intent-filter>
        </activity>

xml佈局：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    tools:context=".activity.chat.ConversationActivity"
    android:orientation="vertical"
    >

    <include
        android:id="@+id/nav_bar"
        layout="@layout/nav_bar"
        android:layout_width="match_parent"
        android:layout_height="55dp"
        />

    <fragment
        android:id="@+id/conversation"
        android:name="io.rong.imkit.fragment.ConversationFragment"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1"
        />

</LinearLayout>

activity中：

 @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_conversation);
        ButterKnife.bind(this);
        StatusBarUtil.setColor(this, UIUtils.getColor(R.color.main_yellow), 0);
    }

其中StatusBarUtil類是個工具類
