在另一个Intent内发送Intent [英] Sending Intent inside of another Intent

问题描述

也许我用的是错误的方法，但是我想在自己的应用程序中响应我的Android AppWidget的click事件并启动一个Activity.设置PendingIntent时，我还有另一个Intent，我想在单击时启动它.我的onStartCommand使用此行:

Perhaps I am going about this the wrong way, but I want to respond to my Android AppWidget's click event within my own app AND launch an Activity. At the time I set the PendingIntent I have another Intent which I want to launch when clicked. My onStartCommand uses this line:

final Intent mLaunchIntent = (Intent) intent.getParcelableExtra(Widget.EXTRA_INTENT);

当我致电setOnClickPendingIntent时，我之前有这条线:

When I call setOnClickPendingIntent I have this line prior:

mSendingIntent.putExtra(Widget.EXTRA_INTENT, (Parcelable) mLaunchIntent);

因此，即使在两行中mLaunchIntent是有效的Intent，第一行仍会丢失大量数据.由于Intent无效，因此调用startActivity失败.

So even though mLaunchIntent is a valid Intent in both lines, the first line is missing a great deal of data. Calling startActivity then fails because the Intent is not valid.

我想知道是否有可能，以及如何在不严格调用putExtras的情况下在另一个Intent内部发送Intent，因为该方法简单地将一个Intent的额外内容添加到了下一个.我想将这两个分开并易于访问.

I am wondering if it is possible, and how, to send an Intent inside of another Intent without strictly calling putExtras because that method simple adds the extras from one Intent to the next. I'd like to keep these two separate and easily accessible.

推荐答案

我实际上已经弄清楚了，解决方案非常简单. mLaunchIntent不应强制转换为Parcelable，否则数据将丢失.

I actually figured it out, the solution was quite simple. mLaunchIntent should not be cast to Parcelable or the data gets lost.

mSendingIntent.putExtra(Intent.EXTRA_INTENT, mLaunchIntent);

这就是我通过另一个Intent发送Intent所需的全部内容.

That was all that I needed to send an Intent through another Intent.
