我自己没有经历过这种崩溃，但是当我检查Firebase Crashlytics时，有些用户确实知道了。
Firebase中的错误：
由java.lang.IllegalStateException引起 EmojiCompat未初始化。请先调用EmojiCompat.init（） com.app.myapp.UserActivity.onCreate
致命异常：java.lang.RuntimeException 无法启动活动ComponentInfo {com.app.myapp / com.app.myapp.UserActivity}：android.view.InflateException：二进制XML文件行＃429：二进制XML文件行＃429：膨胀类androidx.emoji.widget时出错。 EmojiTextView
这是xml中的第429行
<androidx.emoji.widget.EmojiTextView
android:id="@+id/user_description"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:maxLines="12"
android:paddingTop="40dp"
android:paddingLeft="10dp"
android:paddingRight="10dp"
android:paddingBottom="40dp"
android:textAlignment="center"
android:textColor="@color/black" />
，我也刚好在setContentView（R.layout.activity_user）;的下面。在Oncreate内
FontRequest fontRequest = new FontRequest(
"com.google.android.gms.fonts",
"com.google.android.gms",
"Noto Color Emoji Compat",
R.array.com_google_android_gms_fonts_certs);
EmojiCompat.Config config = new FontRequestEmojiCompatConfig(this, fontRequest);
EmojiCompat.init(config);
有什么想法吗？
答案 0 :(得分：0)
在import React, { Component } from 'react'
export default class Addroom extends Component {
constructor(props) {
super(props)
this.state = {
backgroundColor:'white',
room:'',
roomNameInputColor:'white',
roomTypes:["kitchen", "bathroom", "bedroom"],
roomSelected: [''],
roomSel:'',
colorTypes:['red', 'green', 'blue', 'teal'],
colorSelected:[''],
colorSel:'',
};
}
addRoomName = (e) => {
const room = e.target.value;
let roomNameInputColor = 'white';
if (e.target.value.length >= 5) {
roomNameInputColor = 'green';
} else {
roomNameInputColor = 'red';
}
this.setState({ room, addRoomName: room, roomNameInputColor });
}
createRoom=()=> {
this.props.add(this.state.room);
}
createRoomType=()=> {
this.props.addRoomType(this.state.roomSelected);
}
createColorType=()=> {
this.props.addColorType(this.state.colorSelected);
}
setCategory = (roomSel) => {
this.setState({roomSelected : roomSel});
};
setColorCategory = (colorSel) => {
this.setState({colorSelected : colorSel});
};
render() {
return (
<div>
{/* //Select Room Type */}
<select onChange={(e) => this.setCategory(e.target.value)}>{this.state.roomTypes.map((type) =>
<option value={type}>{type}</option>
)}</select><br/>
{/* //Select Room Color */}
<select onChange={(e) => this.setColorCategory(e.target.value)}>{this.state.colorTypes.map((type) =>
<option value={type}>{type}</option>
)}
</select><br/>
<input onChange={this.addRoomName} style={{backgroundColor:this.state.roomNameInputColor}} placeholder='Name Your Room'/><br/>
<button onClick={() => {this.createRoom(); this.createRoomType(); this.createColorType();}}>Create</button>
</div>
)
}
}
类中或在import React, { Component } from 'react'
export default class Room extends Component {
constructor(props) {
super(props)
this.state = {
}
}
render() {
return (
<div>
<h3>Room1: {this.props.r} </h3>
<h3>Room Type1: {this.props.rt}</h3>
<h3>Room Color1: {this.props.ct}</h3>
</div>
)
}
}
之前的版本中初始化该库
