Butter Knife简单使用教程

1.Activity中使用例子

class ExampleActivity extends Activity {  @Bind(R.id.title) TextView title;  @Bind(R.id.subtitle) TextView subtitle;  @Bind(R.id.footer) TextView footer;  @Override public void onCreate(Bundle savedInstanceState) {    super.onCreate(savedInstanceState);    setContentView(R.layout.simple_activity);    ButterKnife.bind(this);    // TODO Use fields...  }}

2.非Activity中使用例子

public class FancyFragment extends Fragment {  @Bind(R.id.button1) Button button1;  @Bind(R.id.button2) Button button2;  @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {    View view = inflater.inflate(R.layout.fancy_fragment, container, false);    ButterKnife.bind(this, view);    // TODO Use fields...    return view;  }}////////////////////////////////////////////////public class FancyFragment extends Fragment {  @Bind(R.id.button1) Button button1;  @Bind(R.id.button2) Button button2;  @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {    View view = inflater.inflate(R.layout.fancy_fragment, container, false);    ButterKnife.bind(this, view);    // TODO Use fields...    return view;  }  @Override public void onDestroyView() {    super.onDestroyView();    ButterKnife.unbind(this);  }}

3.监听事件使用例子

Listeners can also automatically be configured onto methods.@OnClick(R.id.submit)public void submit(View view) {  // TODO submit data to server...}All arguments to the listener method are optional.@OnClick(R.id.submit)public void submit() {  // TODO submit data to server...}Define a specific type and it will automatically be cast.@OnClick(R.id.submit)public void sayHi(Button button) {  button.setText("Hello!");}Specify multiple IDs in a single binding for common event handling.@OnClick({ R.id.door1, R.id.door2, R.id.door3 })public void pickDoor(DoorView door) {  if (door.hasPrizeBehind()) {    Toast.makeText(this, "You win!", LENGTH_SHORT).show();  } else {    Toast.makeText(this, "Try again", LENGTH_SHORT).show();  }}Custom views can bind to their own listeners by not specifying an ID.public class FancyButton extends Button {  @OnClick  public void onClick() {    // TODO do something!  }}Method annotations whose corresponding listener has multiple callbacks can be used to bind to any one of them. Each annotation has a default callback that it binds to. Specify an alternate using the callback parameter.@OnItemSelected(R.id.list_view)void onItemSelected(int position) {  // TODO ...}@OnItemSelected(value = R.id.maybe_missing, callback = NOTHING_SELECTED)void onNothingSelected() {  // TODO ...}
