ButterKnife简单使用

配置参考上一篇博客 http://blog.youkuaiyun.com/ning_gg/article/details/51683028
现在附上简单使用,主要还是自己记性不行，特作此笔记
ButterKnife的地址https://github.com/JakeWharton/butterknife
说真的,这个东西很便捷，少写了好多findViewById和onClick

MainActivity

public class MainActivity extends AppCompatActivity {

    @BindView(R.id.textview) TextView textView;
    @BindString(R.string.app_name) String appName;
    @OnClick(R.id.button1) void myFirstButton(){
        Toast.makeText(MainActivity.this,"显示第一个了",Toast.LENGTH_SHORT).show();
    }
    @OnClick(R.id.button2) void mySecondButton(){
        Toast.makeText(MainActivity.this,"显示第二个了",Toast.LENGTH_SHORT).show();
    }
    @OnClick(R.id.button3) void myThirdButton(){
        third();
    }

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

        textView.setText(appName);
    }

    /**
     * 第三个按钮方法
     */
    private void third(){
        Toast.makeText(MainActivity.this,"显示第三个了",Toast.LENGTH_SHORT).show();
    }
}

Adapter

public class SimpleAdapter extends BaseAdapter {
    private static final String[] CONTENTS =
            "The quick brown fox jumps over the lazy dog".split(" ");

    private final LayoutInflater inflater;

    public SimpleAdapter(Context context) {
        inflater = LayoutInflater.from(context);
    }

    @Override public int getCount() {
        return CONTENTS.length;
    }

    @Override public String getItem(int position) {
        return CONTENTS[position];
    }

    @Override public long getItemId(int position) {
        return position;
    }

    @Override public View getView(int position, View view, ViewGroup parent) {
        ViewHolder holder;
        if (view != null) {
            holder = (ViewHolder) view.getTag();
        } else {
            view = inflater.inflate(R.layout.simple_list_item, parent, false);
            holder = new ViewHolder(view);
            view.setTag(holder);
        }

        String word = getItem(position);
        holder.word.setText("Word: " + word);
        holder.length.setText("Length: " + word.length());
        holder.position.setText("Position: " + position);
        // Note: don't actually do string concatenation like this in an adapter's getView.

        return view;
    }

    static final class ViewHolder {
        @BindView(R.id.word) TextView word;
        @BindView(R.id.length) TextView length;
        @BindView(R.id.position) TextView position;

        ViewHolder(View view) {
            ButterKnife.bind(this, view);
        }
    }
}

一目了然，当我记不住的时候就来看下就明白了。
