https://github.com/JakeWharton/butterknife

引入依赖：在Module:app下的build.gradle的dependencies下：

compile 'com.jakewharton:butterknife:8.5.1' annotationProcessor 'com.jakewharton:butterknife-compiler:8.5.1' 简单使用：

package com.example.administrator.testbutterknife; import android.support.v7.app.AppCompatActivity; import android.os.Bundle; import android.widget.TextView; import butterknife.BindView; import butterknife.ButterKnife; import butterknife.OnClick; public class MainActivity extends AppCompatActivity { @BindView(R.id.text) TextView textView; @OnClick(R.id.button) void update() { textView.setText("UPDATE"); } @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); ButterKnife.bind(MainActivity.this); } }
