問題描述

我使用黃油刀庫完美地注入了視圖.但是當我嘗試實現偵聽器時，例如 onclick 我無法實現它們.以下java代碼將幫助您理解我的問題.

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 代碼:

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);
    }
}

告訴我為什么會這樣.代碼有什么問題嗎?我已經使用以下 URL 配置了與 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.

推薦答案

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(應用程序)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'
}
