Android错误膨胀类EditText

本文介绍了Android错误膨胀类EditText的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我遇到了一个奇怪的问题.每当在Activity中添加EditText时，我的Android应用程序就会崩溃.为了进行测试，我打开了一个新的干净项目，如果还有EditText，新项目也会崩溃.因此，我认为问题是由Android Studio或其他环境设置引起的.

I encountered a strange problem. My Android app would crash whenever I add an EditText in an Activity. To test, I open a new clean project, and the new project will crash if there is an EditText as well. Therefore, I think the problem is caused from Android Studio or other environment setting.

以下是activity_main.xml

Following is the activity_main.xml

 <?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout
    android:id="@+id/activity_main"
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="yichun.myapplication.MainActivity">

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Hello World!"
        android:id="@+id/textView"
        app:layout_constraintLeft_toLeftOf="@+id/activity_main"
        app:layout_constraintTop_toTopOf="@+id/activity_main"
        app:layout_constraintRight_toRightOf="@+id/activity_main"
        app:layout_constraintBottom_toBottomOf="@+id/activity_main"/>
    <EditText
        android:layout_width="218dp"
        android:layout_height="45dp"
        android:inputType="textPersonName"
        android:text="Name"
        android:ems="10"
        tools:layout_editor_absoluteX="90dp"
        android:id="@+id/editText"
        app:layout_constraintBottom_toTopOf="@+id/textView" android:layout_marginBottom="40dp"/>
</android.support.constraint.ConstraintLayout>

MainActivity.java 公共类MainActivity扩展了AppCompatActivity {

MainActivity.java public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }
}

AndroidManifest.xml

AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>

<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:supportsRtl="true"
    android:theme="@style/AppTheme">
    <activity android:name=".MainActivity">
        <intent-filter>
            <action android:name="android.intent.action.MAIN"/>

            <category android:name="android.intent.category.LAUNCHER"/>
        </intent-filter>
    </activity>
</application>

推荐答案

使用gradle插件的2.2.x版本可能会导致此问题.

Using 2.2.x version of the gradle plugin could cause this.

降级可能值得一试:

// project level build.gradle
dependencies {
    classpath 'com.android.tools.build:gradle:2.1.0'
}

我想它最终会被修复，所以未来的读者可以尝试升级而不是降级:)

I suppose it will be fixed eventually, so future readers can try upgrading instead of downgrading :)
