优步请求按钮 onClickListener

Question

我在我的项目中使用 Uber android-api。单击 RequestButton 后，它会将用户导航到 Uber App，但我想在导航到 Uber 应用程序之前处理一些数据。因此，为此，我想要 RequestButton 的 onClickListener。

我已经尝试直接在 requestButton 的对象上提供 onClickListener 然后我得到了事件但它没有导航到 Uber App。

requestButton.setOnClickListener(new View.OnClickListener() 
{
      @Override 
       public void onClick(View v) {

       }
});

Answer 1

如果您想处理 Uber SDK 无法处理的内容，您需要自定义 RequestButton。

Answer 2

为了能够调用您自己的自定义代码在点击 RequestButton 之前，即它的 OnClickListener 回调方法被调用，您必须更改游乐设施内 RequestButton 的代码-android-sdk.

然后在您的 activity 中，您必须调用 RequestButton 对象上的 setCustomPreOnClickListener：

public void rideRequestButtonWithCustomPreOnClickListener() {
        RequestButton uberButtonBlack = (RequestButton) findViewById(R.id.uber_button_black);
        RequestButton uberButtonWhite = (RequestButton) findViewById(R.id.uber_button_white);

        RideParameters rideParameters = new RideParameters.Builder()
                .setProductId(UBERX_PRODUCT_ID)
                .setPickupLocation(PICKUP_LAT, PICKUP_LONG, PICKUP_NICK, PICKUP_ADDR)
                .setDropoffLocation(DROPOFF_LAT, DROPOFF_LONG, DROPOFF_NICK, DROPOFF_ADDR)
                .build();

        uberButtonBlack.setRideParameters(rideParameters);
        uberButtonWhite.setRideParameters(rideParameters);

        uberButtonBlack.setCustomPreOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Log.d(TAG, "Custom code for black button called before UberRequestButton's onClick() listener");
            }
        });

        uberButtonWhite.setCustomPreOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Log.d(TAG, "Custom code for white button called before UberRequestButton's onClick() listener");
            }
        });
    }

另一种方法是创建自定义 class:

package com.uber.sdk.android.rides.samples;

import android.content.Context;
import android.util.AttributeSet;
import android.util.Log;
import android.view.View;

import com.uber.sdk.android.rides.RequestButton;

public class CustomUberRequestButton extends RequestButton implements View.OnClickListener {
    private static final String TAG = CustomUberRequestButton.class.getSimpleName();

    public CustomUberRequestButton(Context context) {
        super(context);
    }

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

    public CustomUberRequestButton(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
    }

    @Override
    public void onClick(View v) {
        Log.d(TAG, "Custom code before calling UberRequestButton's onClick() listener");

        // Explicitly need to call UberRequestButton onClick() listener
        super.onClick(v);
    }
}

你可以这样使用它：

/**
 * Please make sure you replace com.uber.sdk.android.rides.RequestButton
 * with com.uber.sdk.android.rides.samples.CustomUberRequestButton inside
 * the res/layout/activity_sample.xml file, otherwise you will get a ClassCastException.
 */
public void rideRequestButtonWithCustomSubclassOnClickListener() {
    CustomUberRequestButton uberButtonBlack = (CustomUberRequestButton) findViewById(R.id.uber_button_black);
    CustomUberRequestButton uberButtonWhite = (CustomUberRequestButton) findViewById(R.id.uber_button_white);

    RideParameters rideParameters = new RideParameters.Builder()
            .setProductId(UBERX_PRODUCT_ID)
            .setPickupLocation(PICKUP_LAT, PICKUP_LONG, PICKUP_NICK, PICKUP_ADDR)
            .setDropoffLocation(DROPOFF_LAT, DROPOFF_LONG, DROPOFF_NICK, DROPOFF_ADDR)
            .build();

    uberButtonBlack.setRideParameters(rideParameters);
    uberButtonWhite.setRideParameters(rideParameters);
}

使用自定义 class 如果需要，您还可以设置自定义 preOnClickListener。请参阅上述提交中的 rideRequestButtonWithCustomSubclassAndPreOnClickListener 方法。

@bitek 走在正确的轨道上，但这里是覆盖 RideRequestButton 的完整解决方案

public class CustomUberButton extends RideRequestButton implements 
 View.OnClickListener {
private View.OnClickListener internalListener;
private View.OnClickListener preClickListener;

public CustomUberButton(Context context) {
    super(context);
}

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

public CustomUberButton(Context context, AttributeSet attrs, int defStyleAttr) {
    super(context, attrs, defStyleAttr);
}

public void setPreClickListener(OnClickListener preClickListener) {
    this.preClickListener = preClickListener;
}

@Override
public void setOnClickListener(@Nullable OnClickListener l) {
    // redirect the listener to us but keep the original listener registered by the original button to reuse later.
    internalListener = l;
    super.setOnClickListener(this);
}

@Override
public void onClick(View view) {
    preClickListener.onClick(view);
    internalListener.onClick(view);
}

}

上面的class可以用在xml

<com.example.android.takemehome.uber.CustomUberButton
    android:id="@+id/btn_uber"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    uber:ub__style="black" />

和 activity 看起来像

mUberButton = (CustomUberButton) findViewById(R.id.btn_uber);
mUberButton.setPreClickListener(this);

在这种情况下，activity 也实现了 View.OnClickListener
