Android Studio中 Android butterKnife Zelezny和 Android Parcelable code generator的使用（备忘录）

Android butterKnife Zelezny和Android Parcelable code generator的介绍与使用

介绍：

Android butterKnife Zelezny是一款注解框架插件，优点是节约开发时间和减少代码量，减少开发是繁琐的开发量，缺点看个人。我认为一种新的工具或框架，凡是在某种业务场景下，利大于弊，那就是值得使用。

具体使用参照

Android Parcelable code generator，词穷，暂时想不到如何描述更好，就是一款自动让对象实现Parcelable的插件吧，免得你写重复代码玩意，更快更方便。

使用：

a、首先打开Android Studio

b、然后点击Settings -> Plugins -> Browse repositories -> 搜索Android butterKnife Zelezny -> Install plugin

c、Android Parcelable code generator安装方式同b操作，安装完成重启AS

d、新建项目，具体如何使用，借用一张动态图，不知图作者是谁，先借用啦，有问题请留言。



示例代码：

布局文件activity_plugin

<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:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context="cn.richinfo.thinkdrive.ui.activities.PluginActivity">

<TextView
android:id="@+id/textView"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />

<Button
android:id="@+id/button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:layout_below="@+id/textView"
android:layout_marginTop="45dp"
android:text="Test Button" />

<Button
android:id="@+id/button2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentEnd="true"
android:layout_alignParentRight="true"
android:layout_alignTop="@+id/button"
android:text="New Button" />

</RelativeLayout>

PluginActivity类

import android.content.Intent;
import android.os.Bundle;
import android.support.v7.app.ActionBarActivity;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;

import butterknife.Bind;
import butterknife.ButterKnife;
import butterknife.OnClick;
import butterknife.OnLongClick;
import cn.richinfo.thinkdrive.R;
import cn.richinfo.thinkdrive.logic.db.model.UserInfo;
import cn.richinfo.thinkdrive.logic.model.response.MyInfoDao;

public class PluginActivity extends ActionBarActivity {

@Bind(R.id.textView)
TextView textView;
@Bind(R.id.button)
Button button;
@Bind(R.id.button2)
Button button2;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_plugin);
ButterKnife.bind(this);
}

@OnClick({R.id.button, R.id.button2})
public void onButtonClick(View v) {
switch (v.getId()) {
case R.id.button:
textView.setText("i am from test button " + "onButtonClick");
redirectToSecondActivity(new MyInfoDao("羊习习", "XX Company"));
break;

case R.id.button2:
textView.setText("i am from new button2 " + "onButtonClick");
break;
}
}

@OnLongClick(R.id.button)
public boolean onButtonLongClick(View v) {
textView.setText("i am from test button " + "onButtonLongClick");
return true;
}

private void redirectToSecondActivity(MyInfoDao mUserInfo) {
Intent intent = new Intent(PluginActivity.this, SecondActivity.class);
//直接通过intent传输实现过Parcelable的对象
intent.putExtra("userinfo", mUserInfo);
startActivity(intent);
}

@Override
protected void onDestroy() {
super.onDestroy();
ButterKnife.unbind(this);
}
}

布局文件activity_second

<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:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context="cn.richinfo.thinkdrive.ui.activities.SecondActivity">

<TextView
android:id="@+id/tv_content"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />

</RelativeLayout>

SecondActivity类

import android.os.Bundle;
import android.support.v7.app.ActionBarActivity;
import android.widget.TextView;

import butterknife.Bind;
import butterknife.ButterKnife;
import cn.richinfo.thinkdrive.R;

public class SecondActivity extends ActionBarActivity {

@Bind(R.id.tv_content)
TextView tvContent;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_second);
ButterKnife.bind(this);
tvContent.setText(getIntent().getExtras().getParcelable("userinfo").toString());
}

}

MyInfoDao 类

import android.os.Parcel;
import android.os.Parcelable;

/**
* Created by Administrator on 2015/11/6.
*/
public class MyInfoDao implements Parcelable {

private String name;
private String company;

public MyInfoDao(String name, String company) {
this.name = name;
this.company = company;
}

public String getName() {
return name;
}

public void setName(String name) {
this.name = name;
}

public String getCompany() {
return company;
}

public void setCompany(String company) {
this.company = company;
}

@Override
public String toString() {
return "[" + getName() + " " + getCompany() + "]";
}

@Override
public int describeContents() {
return 0;
}

@Override
public void writeToParcel(Parcel dest, int flags) {
dest.writeString(this.name);
dest.writeString(this.company);
}

/**
* 以下都是通过Android Parcelable code generator自动生成
*/

public MyInfoDao() {
}

protected MyInfoDao(Parcel in) {
this.name = in.readString();
this.company = in.readString();
}

public static final Parcelable.Creator<MyInfoDao> CREATOR = new Parcelable.Creator<MyInfoDao>() {
public MyInfoDao createFromParcel(Parcel source) {
return new MyInfoDao(source);
}

public MyInfoDao[] newArray(int size) {
return new MyInfoDao[size];
}
};
}

运行之后的效果：
