java - Android:在自定义 View 中覆盖 onClick 时 OnClick 不起作用

Question

我创建了一个自定义 View 。我的自定义 View 扩展自 RelativeLayout:

public class CircleProgressButton extends RelativeLayout {...

在我的自定义 View 中，我有一个按钮:

private void initView(Context context, AttributeSet attrs) {
    TypedArray typedArray = context.getTheme().obtainStyledAttributes(
            attrs, R.styleable.ProgressButton, 0, 0
    );
    try {
        progressHeight = typedArray.getInt(R.styleable.ProgressButton_progress_height, progressHeight);
        progressWidth = typedArray.getInt(R.styleable.ProgressButton_progress_width, progressWidth);
        progressIconSuccess = typedArray.getResourceId(R.styleable.ProgressButton_progress_iconSuccess, R.drawable.ic_done);
        progressIconFail = typedArray.getResourceId(R.styleable.ProgressButton_progress_iconfail, R.drawable.ic_fail);
        progressText = typedArray.getString(R.styleable.ProgressButton_progress_text);
        progressBackgroundImage = typedArray.getDrawable(R.styleable.ProgressButton_progress_button_background);
    } finally {
        typedArray.recycle();
    }

    initButton();
    initProgressBar();
    initImageView();
}
    private void initButton() {
        button = new AppCompatButton(getContext());
        LayoutParams button_params = new LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);
        button_params.addRule(RelativeLayout.CENTER_IN_PARENT, RelativeLayout.TRUE);
        button.setLayoutParams(button_params);
        button.setText(TextUtils.isEmpty(progressText) ? "Button" : progressText);
        button.setGravity(Gravity.CENTER);
        StateListDrawable background = new StateListDrawable();
        background.addState(StateSet.WILD_CARD, progressBackgroundImage);
//        background.addState(new int[]{android.R.attr.state_pressed}, progressBackgroundImagePressed);
        button.setBackground(background);
        button.setClickable(false);
/*        button.setOnClickListener(v -> {
            if (imageView.getVisibility() == VISIBLE) imageView.setVisibility(GONE);
            progressBar.setVisibility(VISIBLE);
        });*/
        addView(button);
    }

现在我将自定义 View 附加到 fragment 布局:

<com.tazik.circleprogressbutton.CircleProgressButton
    android:id="@+id/btn_save"
    android:layout_width="150dp"
    android:layout_height="70dp"
    app:progress_height="30"
    app:progress_width="30"
    app:progress_text = "@string/save_btn"
    app:progress_iconfail="@drawable/ic_fail"
    app:progress_iconSuccess="@drawable/ic_done"
    app:progress_button_background="@drawable/mybutton"
    android:clickable="true"/>

在我的 fragment 中，我像这样绑定(bind) fragment 布局:

binding = DataBindingUtil.inflate(inflater, R.layout.fragment_marhaleh, container, false);
    binding.btnSave.setOnClickListener(v->{
        Log.i("======", "onSaveClicked: ");
        // do my stuff
    });

运行应用程序并单击 btnSave 后，logcat 上将显示日志。

现在我想在我的自定义 View 中重写 OnClick，因此按顺序，在我的自定义 View 中我实现了 View.OnClickListener :

public class CircleProgressButton extends RelativeLayout implements View.OnClickListener {
private OnClickListener listener;

@Override
public void setOnClickListener(@Nullable View.OnClickListener l) {
    listener = l;
}

我重写了 onClick:

@Override
public void onClick(View v) {
    if(listener != null){
        if (imageView.getVisibility() == VISIBLE) imageView.setVisibility(GONE);
        progressBar.setVisibility(VISIBLE);
   }

}

现在，当我点击 btnSave 运行应用程序后，日志没有出现，这意味着

 binding.btnSave.setOnClickListener(v->{
    Log.i("======", "onSaveClicked: ");
    // do my stuff
});

不工作？发生了什么事？

Answer 1

尝试这对我有用，在 CircleProgressButton 类中添加此功能:

private void init(){
    setOnClickListener(this);
}

并在所有构造函数上调用 init() 。删除这个

@Override
public void setOnClickListener(@Nullable View.OnClickListener l) {
 listener = l;
}

像这样编辑这个方法:

@Override
public void onClick(View v) {
    if (imageView.getVisibility() == VISIBLE) imageView.setVisibility(GONE);
    progressBar.setVisibility(VISIBLE);
}

点击触发按钮

binding.btnSave.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            binding.btnSave.onClick(v);
            Log.i("======", "onSaveClicked: ");
            //code
        }
    });

这之后应该是工作
