我如何在本地添加 ButterKnife(无远程依赖项)
How i can add ButterKnife Locally (No remote dependencies)
我已下载 'butterknife-8.8.1.aar' 、 'butterknife-annotations-8.8.1.jar' 和 'butterknife-compiler-8.8.1.jar' 并添加到项目中。当我启动应用程序时,我收到视图的 NullPointer 异常。
public class MainActivity extends AppCompatActivity {
@BindView(R.id.tv_welcome)
TextView textView;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ButterKnife.bind(this);
textView.setText("Butter knife worked!");
}
}
XML
<TextView
android:id="@+id/tv_welcome"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Hello World!"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintTop_toTopOf="parent" />
Gradle 文件
dependencies {
implementation fileTree(include: ['*.jar'], dir: 'libs')
implementation 'com.android.support:appcompat-v7:28.0.0'
implementation 'com.android.support.constraint:constraint-layout:1.1.3'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.2'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
// ButterKnife
implementation files('libs/butterknife-annotations-8.8.1.jar')
implementation files('libs/butterknife-compiler-8.8.1.jar')
implementation project(':butterknife-8.8.1')}
如果您在 gradle 中正确添加它并构建应用程序,它应该会自动将 butterknife
添加到您的应用程序中。
无需手动下载。
只有这样才能完成工作:
dependencies {
implementation 'com.jakewharton:butterknife-gradle-plugin:10.1.0'
}
为了让 ButterKnife 正常工作,我们需要添加三个模块:
- butterknife-注释
- butterknife-reflect
butterknife-runtime
implementation project(':butterknife-annotations')
implementation project(':butterknife-reflect')
implementation project(':butterknife-runtime')
