Java 方法“;onClick";在巴特刀是不是工作?
这是主要活动:Java 方法“;onClick";在巴特刀是不是工作?,java,android,butterknife,Java,Android,Butterknife,这是主要活动: package com.example.a10648.demo; import android.os.Bundle; import android.support.v7.app.AppCompatActivity; import android.widget.Button; import android.widget.Toast; import butterknife.BindView; import butterknife.ButterKnife; import butte
package com.example.a10648.demo;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.widget.Button;
import android.widget.Toast;
import butterknife.BindView;
import butterknife.ButterKnife;
import butterknife.OnClick;
public class MainActivity extends AppCompatActivity {
@BindView(R.id.button)
Button button;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ButterKnife.bind(this);
}
@OnClick(R.id.button)
public void onClick() {
Toast.makeText(MainActivity.this,"ok",Toast.LENGTH_SHORT).show();
}
}
这是xml文件:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout 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"
tools:context="com.example.a10648.demo.MainActivity">
<Button
android:id="@+id/button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Button!" />
</RelativeLayout>
插入缓冲刀的方法无效,
当我点击按钮时,没有要显示的祝酒词?
我不知道为什么会发生这种情况?看起来您还应该包括ButterKnife编译器:
compile 'com.jakewharton:butterknife:8.0.1'
apt 'com.jakewharton:butterknife-compiler:8.0.1'
首先,确保您的项目级别build.gradle如下所示:
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:2.1.0'
classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8'
}
}
请特别注意这一行代码。
不要忽视
classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8'
apply plugin: 'com.neenbedankt.android-apt'
compile 'com.jakewharton:butterknife:8.0.1'
apt 'com.jakewharton:butterknife-compiler:8.0.1'
然后,看看你的应用程序/build.gradle
apply plugin: 'com.android.application'
apply plugin: 'com.neenbedankt.android-apt'
android {
compileSdkVersion 23
buildToolsVersion "23.0.3"
defaultConfig {
applicationId "com.example.a10648.demo"
minSdkVersion 18
targetSdkVersion 23
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:23.3.0'
compile 'com.jakewharton:butterknife:8.0.1'
apt 'com.jakewharton:butterknife-compiler:8.0.1'
}
apply plugin: 'com.android.application'
apply plugin: 'android-apt'
android {
compileSdkVersion 23
buildToolsVersion "23.0.3"
defaultConfig {
applicationId "com.example.a10648.demo"
minSdkVersion 18
targetSdkVersion 23
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:23.3.0'
compile 'com.jakewharton:butterknife:8.4.0'
apt 'com.jakewharton:butterknife-compiler:8.4.0'
}
请特别注意三行代码。
不要忽视
classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8'
apply plugin: 'com.neenbedankt.android-apt'
compile 'com.jakewharton:butterknife:8.0.1'
apt 'com.jakewharton:butterknife-compiler:8.0.1'
那么,一切都好了!我太高兴了!
多谢各位一叶飘舟
这是他在CSDN中的个人页面
如果您阅读自述,您可以看到-> 配置您的项目级build.gradle以包含“android apt”插件:
classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8'
所以build.gradle:
buildscript {
repositories {
mavenCentral()
}
dependencies {
classpath 'com.android.tools.build:gradle:2.2.2'
classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8'
}
}
allprojects {
repositories {
jcenter()
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}
然后,在模块级build.gradle中应用“android apt”插件,并添加黄油刀依赖项:
apply plugin: 'android-apt'
android {
...
}
dependencies {
compile 'com.jakewharton:butterknife:8.4.0'
apt 'com.jakewharton:butterknife-compiler:8.4.0'
}
你的身材怎么样,格雷德尔

有什么错误吗?@VishweshJainkuniya这没用。这个问题是关于毛刀的
