活动拒绝启动 [英] Activity refuses to start

问题描述

现在我的第一个活动是显示正常，但点击按钮不会弹出下一个活动。

Now my first Activity is displaying fine, but clicking the button does not bring up the next Activity. I stepped through this code:

@Override
public void onClick(View v) {
Intent configure = new  Intent(OnDemandAndAutomatic_Activity.this, Configure_Activity.class);  
OnDemandAndAutomatic_Activity.this.startActivity(configure);
}

......，似乎一切正常，但除了打破我进入Debug透视图，有了这个措辞在控制台窗格中什么都没有发生，：

...and it seemed to run fine, but nothing happened, except breaking me into the Debug Perspective, with this verbiage in the Console pane:

[2012-02-01 21:01:35 - ddms] execute: returning
[2012-02-01 21:01:35 - Unexpected error while launching logcat. Try reselecting the device.] device not found
com.android.ddmlib.AdbCommandRejectedException: device not found
    at com.android.ddmlib.AdbHelper.setDevice(AdbHelper.java:736)
    at com.android.ddmlib.AdbHelper.executeRemoteCommand(AdbHelper.java:373)
    at com.android.ddmlib.Device.executeShellCommand(Device.java:372)
    at com.android.ddmuilib.logcat.LogCatReceiver$1.run(LogCatReceiver.java:100)
    at java.lang.Thread.run(Unknown Source)"

...什么可能会导致此任何想法？

...any ideas on what might cause this?

更新： 我也试图改变按钮点击code到这一点：

Update: I also tried changing the button click code to this:

Intent configure = new  Intent(this, Configure_Activity.class);  
startActivity(configure);

...但它没有什么区别。

...but it makes no difference.

在控制台中的最后一行是：

The last line in Console is:

[2012-02-01 21:31:46 - ddms] Forwarding client reply 0x166 to [Debugger 8647-->390 active]

有没有在LogCat中......？！

There is nothing in LogCat...?!

推荐答案

荡我愣尸体！

这个问题是我已经忘了添加活动要开始了清单！

The problem was I had neglected to add the Activity to be started to the Manifest!

原谅我，而我去和自己较劲无情。

Excuse me while I go and berate myself mercilessly.

其实，我很高兴能认识我的令人震惊的错误。

Actually, I'm just happy to have realized my egregious blunder.
