ViewFinder

一个学习 APT 的玩具项目, 实现了简单的 View 注入功能, 完成了类似于 ButterKnife 中的 @BindView 和 @OnClick 两个注解的功能。

A simple project to study with APT in Android, and it can work well like @BindView & @OnClick annotations in ButterKnife to inject for views.

Before

public class MainActivity extends AppCompatActivity {

    TextView mTextView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        mTextView = (TextView) findViewById(R.id.tv);
        mTextView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                Toast.makeText(MainActivity.this, "onTextClick", Toast.LENGTH_SHORT).show();
            }
        });
    }
}

After

public class MainActivity extends AppCompatActivity {

    @BindView(R.id.tv) TextView mTextView;
    @OnClick(R.id.btn)
    public void onButtonClick() {
        Toast.makeText(this, "onButtonClick", Toast.LENGTH_SHORT).show();
    }

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        ViewFinder.inject(this);
    }
}
