Question

ButterKnife's OnClick侦听器出现一个奇怪的问题。在下面打开我的自定义视图时，打开视图时，OnClick侦听器将自动运行。以下代码可帮助您了解我的问题。

$args = array(
    'post_type'=> 'products',
    'posts_per_page'  => 4,
    'meta_key'      => 'focus_product',
    'meta_value'    => 1
);

}

IMO之所以发生这种情况，是因为我在构造函数中调用了OnClick侦听器，因此在视图创建（创建后）时自然会在运行它们。有人可以帮助我了解确切的问题在哪里以及如何解决吗？

我的ButterKnife版本：

public class UserMenuFragment extends LinearLayout {
@BindView(R.id.buttonBlockUser)
Button buttonBlockUser;
@BindView(R.id.buttonMuteUser)
Button buttonMuteUser;
@BindView(R.id.buttonHideYourPreset)
Button buttonHideYourPreset;
@BindView(R.id.buttonTurnOnNotifs)
Button buttonTurnOnNotifs;

public UserMenuFragment(Context context, AttributeSet attrs, int defStyle) {
    super(context, attrs, defStyle);
    initView();
}

public UserMenuFragment(Context context, AttributeSet attrs) {
    super(context, attrs);
    initView();
}

public UserMenuFragment(Context context) {
    super(context);
    initView();
}

private void initView() {
    View view = inflate(getContext(), R.layout.fragment_user_menu, null);
    addView(view);
    bindViewWithButterKnife(this, view);
    onButtonReportUserClicked();
    onButtonBlockUserClicked();
    onButtonMuteUserClicked();
    onButtonHideYourPresetClicked();
    onButtonCopyProfileLinkClicked();
    onButtonTurnOnNotifsClicked();
}

@OnClick(R.id.buttonReportUser)
void onButtonReportUserClicked() {
    Toast.makeText(getContext(), "User Reported!", Toast.LENGTH_SHORT).show();
}

@OnClick(R.id.buttonBlockUser)
void onButtonBlockUserClicked() {
    Toast.makeText(getContext(), "User Blocked!", Toast.LENGTH_SHORT).show();
    changeButtonText(buttonBlockUser, R.string.unblock_user_text);
}

@OnClick(R.id.buttonMuteUser)
void onButtonMuteUserClicked() {
    Toast.makeText(getContext(), "User Muted!", Toast.LENGTH_SHORT).show();
    changeButtonText(buttonMuteUser, R.string.unmute_user_text);
}

@OnClick(R.id.buttonHideYourPreset)
void onButtonHideYourPresetClicked() {
    Toast.makeText(getContext(), "User preset hided!", Toast.LENGTH_SHORT).show();
    buttonHideYourPreset.setText(getContext().getString(R.string.show_your_preset_text));
    changeButtonText(buttonHideYourPreset, R.string.show_your_preset_text);
}

@OnClick(R.id.buttonCopyProfileLink)
void onButtonCopyProfileLinkClicked() {
    Toast.makeText(getContext(), "User's profile link copied!", Toast.LENGTH_SHORT).show();
}

@OnClick(R.id.buttonTurnOnNotifs)
void onButtonTurnOnNotifsClicked() {
    Toast.makeText(getContext(), "User's notification is off now!!", Toast.LENGTH_SHORT).show();
    changeButtonText(buttonTurnOnNotifs, R.string.turn_off_notification_text);
}

private void changeButtonText(Button button, int newText) {
    button.setText(getContext().getString(newText));
}

private void bindViewWithButterKnife(UserMenuFragment whichFragment, View view) {
    ButterKnife.bind(whichFragment, view);
}

Answer 1

将initView()更改为：

private void initView() {
    View view = inflate(getContext(), R.layout.fragment_user_menu, null);
    addView(view);
    bindViewWithButterKnife(this, view);
}

我认为您不需要调用方法，注释已经可以完成设置侦听器的工作了，对吧？

在自定义视图中创建视图后不久，ButterKnife OnClick侦听器将运行
