如何更改 ZoomButtonsController 中按钮触摸的颜色

Question

我正在我的应用中实现 ZoomButtonsContainer。除了 + 和 - 按钮按下时的颜色是一种黄色赭石外，它运行良好。我想更改它以反映我的应用程序的颜色。我正在使用 Theme.AppCompat.Light.DarkActionBar。

我已经尝试在我的活动主题中覆盖一些样式属性，但没有任何效果。我尝试了以下方法：

 <item name="android:colorPressedHighlight">@color/plum</item>
 <item name="android:colorActivatedHighlight">@color/plum</item>

有什么解决办法吗？

Answer 1

我已经解决了这个问题，通过一个更好的更激烈的解决方案绕过它。我已经在 ZoomButtonsController 中用我自己的布局完全替换了按钮。我在下面显示代码以防万一这对任何人有用。

步骤：

1. 按照我需要的样式为按钮创建一个布局，但要参考使用的默认布局。
2. 为按钮创建背景以显示启用/按下/默认所需的颜色。
3. 使用此布局创建一个 My_ZoomControls 类，根据需要从默认 ZoomControls 中获取代码。
4. 创建一个从 ZoomButtonsController 扩展但引用 My_ZoomControls 的 My_ZoomButtonsController。
5. 通过切换默认布局并将其替换为我的自定义布局来进行初始化。
6. 包含代码以调用 setVisible(false) 与窗口分离并根据 ZoomButtonsController 的文档更改可见性。
7. 请注意，根据解决方案here，您需要注意控制器“ownerView”

My_ZoomControls

public class My_ZoomControls extends LinearLayout {

private final ZoomButton mZoomInButton;
private final ZoomButton mZoomOutButton;

public My_ZoomControls(Context context) {
    super(context);
    setFocusable(false);

    LayoutInflater inflater = (LayoutInflater) context
            .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    inflater.inflate(R.layout.zoom_controls, this, true);

    mZoomInButton = (ZoomButton) findViewById(R.id.zoomIn);
    mZoomOutButton = (ZoomButton) findViewById(R.id.zoomOut);

public void setOnZoomInClickListener(OnClickListener listener) {
    mZoomInButton.setOnClickListener(listener);
}

public void setOnZoomOutClickListener(OnClickListener listener) {
    mZoomOutButton.setOnClickListener(listener);
}

@Override
public boolean onTouchEvent(MotionEvent event) {
    return true;
}

public void setIsZoomInEnabled(boolean isEnabled) {
    mZoomInButton.setEnabled(isEnabled);
}

public void setIsZoomOutEnabled(boolean isEnabled) {
    mZoomOutButton.setEnabled(isEnabled);
}

}

My_ZoomButtonsController

public class My_ZoomButtonsController extends ZoomButtonsController {

private My_ZoomControls mControls;
private OnZoomListener mZoomListener;
private View.OnAttachStateChangeListener mAttachStateChangeListener;

public My_ZoomButtonsController(View ownerView) {
    super(ownerView);
}

public void setZoomControls(My_ZoomControls mControls) {
    this.mControls = mControls;
    this.mControls.setOnZoomInClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            if (mZoomListener != null) mZoomListener.onZoom(true);
        }
    });
    this.mControls.setOnZoomOutClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            if (mZoomListener != null) mZoomListener.onZoom(false);
        }
    });
    this.mControls.addOnAttachStateChangeListener(new View.OnAttachStateChangeListener() {
        @Override
        public void onViewAttachedToWindow(View v) {
            if (mAttachStateChangeListener != null) mAttachStateChangeListener.onViewAttachedToWindow(v);
        }

        @Override
        public void onViewDetachedFromWindow(View v) {
            if (mAttachStateChangeListener != null) mAttachStateChangeListener.onViewDetachedFromWindow(v);

public void setOnZoomListener(OnZoomListener listener) {
    mZoomListener = listener;
}

public void setOnAttachStateChangeListener(View.OnAttachStateChangeListener listener) {
    mAttachStateChangeListener = listener;
}

@Override
public void setZoomOutEnabled(boolean enabled) {
    mControls.setIsZoomOutEnabled(enabled);
}

@Override
public void setZoomInEnabled(boolean enabled) {
    mControls.setIsZoomInEnabled(enabled);
}

}

实施。 zoomInGrid 是我将应用特定代码放大的地方。

private void setZoomButtonsController() {
    pZoomButtonsController = new My_ZoomButtonsController(pBtnSort);
    ViewGroup container = pZoomButtonsController.getContainer();
    View controls = pZoomButtonsController.getZoomControls();
    ViewGroup.LayoutParams params = controls.getLayoutParams();
    container.removeView(controls);
    My_ZoomControls layout = new My_ZoomControls(My_Application_Base.getInstance().getApplicationContext());
    container.addView(layout, params);
    pZoomButtonsController.setZoomControls(layout);
    pZoomButtonsController.setOnZoomListener(new ZoomButtonsController.OnZoomListener() {

        @Override
        public void onZoom(boolean zoomIn) {
            zoomInGrid(zoomIn);
        }

        @Override
        public void onVisibilityChanged(boolean visible) {
            if ((!visible) && (pZoomButtonsController != null)) {
                pZoomButtonsController.setVisible(false);
            }
        }
    });
    pZoomButtonsController.setOnAttachStateChangeListener(new View.OnAttachStateChangeListener() {
        @Override
        public void onViewAttachedToWindow(View v) {
        }

        @Override
        public void onViewDetachedFromWindow(View v) {
            if (pZoomButtonsController != null) {
                pZoomButtonsController.setVisible(false);
            }
        }
    });
}
