android studio引入butterknife支持
1.应用的build.gradle添加
apply plugin: 'com.android.application'
//butterknife添加下面一行代码
apply plugin: 'android-apt'
android {
...
}
dependencies {
....
//butterknife添加下面两行代码
compile 'com.jakewharton:butterknife:8.4.0'
apt 'com.jakewharton:butterknife-compiler:8.4.0'
}
2.项目的build.gradle中添加
buildscript {
dependencies {
classpath 'com.android.tools.build:gradle:2.2.0'
//butterknife添加下面一行代码
classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8'
}
}
3.检查是否成功
a.在activity_main.xml中添加一个TextView, id为tv_hello
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/activity_main"
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="mediaplay.test.git.mediaplaydemo.MainActivity">
<TextView
android:id="@+id/tv_hello"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Hello World!" />
</RelativeLayout>
b.MainActivity.java中使用
public class MainActivity extends AppCompatActivity {
//2.添加映射关系
@BindView(R.id.tv_hello) TextView mTvhello;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//1.添加绑定
ButterKnife.bind(this);
//3.使用
mTvhello.setText("你好, butterknife");
}
}
3.运行程序,TextView的内容变化,则配置成功。
