時,當我試圖做到這一點:butterKnife返回null結合視圖(8.6.0)
...
public class LoginActivity extends AppCompatActivity {
@BindView(R.id.login_form) View loginForm;
...
loginForm
越來越null
。我試圖遵循其他答案,沒有任何工作(例如)。我也完全按照它在butterKnife配置頁面中所說的那樣行事,但沒有奏效。我究竟做錯了什麼?
模塊gradle這個:
apply plugin: 'com.android.application'
apply plugin: 'com.jakewharton.butterknife'
android {
compileSdkVersion 25
buildToolsVersion "25.0.3"
defaultConfig {
applicationId "name"
minSdkVersion 22
targetSdkVersion 25
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
exclude group: 'com.android.support', module: 'support-annotations'
})
compile 'com.jakewharton:butterknife:8.6.0'

compile 'com.android.support:design:25.3.1'
compile 'com.android.support.constraint:constraint-layout:1.0.2'

}
項目gradle這個:
dependencies {
classpath 'com.android.tools.build:gradle:2.3.3'
classpath 'com.jakewharton:butterknife-gradle-plugin:8.6.0'
安置自己的onCreate方法,並在那裏你有login_form的XML。 –
選中此行添加「ButterKnife.bind(this);」在onCreate方法中。 –
