问题描述

我使用黄油刀库完美地注入了视图.但是当我尝试实现侦听器时，例如 onclick 我无法实现它们.以下java代码将帮助您理解我的问题.

I injected views perfectly using butterknife library. But when I try to implement listeners, for example onclick I'm not able to implement them. Following java code will help you to understand my problem.

Java 代码:

public class LoginActivity extends ActionBarActivity{
    @InjectView(R.id.toolbar) Toolbar toolbar;
    @InjectView(R.id.btn_login) Button login;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.login);
        ButterKnife.inject(this);

        initialize();
        //initListeners();

        @OnClick(R.id.btn_login)
        public void submit(View view) {
          // TODO submit data to server...
        }
    }

    /*private void initListeners() {
        @OnClick(R.id.btn_login)
        public void login(){

        }
    }*/

    private void initialize() {
        setSupportActionBar(toolbar);
        getSupportActionBar().setIcon(R.drawable.toolbar_icon);
        getSupportActionBar().setTitle(null);
        getSupportActionBar().setDisplayShowHomeEnabled(true);
    }
}

告诉我为什么会这样.代码有什么问题吗?我已经使用以下 URL 配置了与 ButterKnife 兼容的 IDE.

Tell me why it is happening. Anything wrong in code? I've already configured the IDE which is compatible with ButterKnife by using following URL.

推荐答案

MainActivity.java

MainActivity.java

import android.os.Bundle;
import android.support.v7.app.ActionBarActivity;
import android.view.View;
import android.widget.Button;
import android.widget.Toast;

import butterknife.ButterKnife;
import butterknife.InjectView;
import butterknife.OnClick;


public class MainActivity extends ActionBarActivity {


    @InjectView(R.id.button)
    Button login;

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


    }


    @OnClick(R.id.button)
    void submitButton(View view) {
            Toast.makeText(this, "Click", Toast.LENGTH_SHORT).show();
    }
}

以及activity_main.xml 部分

and the activity_main.xml part

<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"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    android:paddingBottom="@dimen/activity_vertical_margin"
    tools:context=".MainActivity">


    <Button
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="New Button"
        android:id="@+id/button"
        android:layout_alignParentTop="true"
        android:layout_alignParentLeft="true"
        android:layout_alignParentStart="true"
        android:layout_marginLeft="59dp"
        android:layout_marginStart="59dp"
        android:layout_marginTop="132dp"
        />
</RelativeLayout>

在 build.gradle 文件(应用程序)中

in build.gradle file(app)

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:22.0.0'
    compile 'com.jakewharton:butterknife:6.1.0'
}
