我知道有很多关于这个问题,但我只是不能弄清楚为什么我的程序一直加载错误的活动,即使我已经使正确的一个默认的manifest。下面是一些代码:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="swin.examples"
android:versionCode="1"
android:versionName="1.0">
<application android:icon="@drawable/icon" android:label="@string/app_name">
<activity android:name="swin.examples.TemperatureConvertor"
android:label="@string/app_name">
</activity>
<activity android:name="swin.examples.FeetToCmConvertor"
android:label="@string/app_name">
</activity>
<activity android:name="swin.examples.Main" android:label="@string/app_name">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
如果它不在清单中,我认为问题就在这里:
package swin.examples;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
public class Main extends Activity
{
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
initializeUI();
}
private void initializeUI()
{
Button btnCm = (Button)findViewById(R.id.btnFeet);
btnCm.setOnClickListener(btnFeetListener);
Button convertButton = (Button)findViewById(R.id.btnTemp);
convertButton.setOnClickListener(btnTempListener);
}
/** Handle convert button click */
private OnClickListener btnTempListener = new OnClickListener()
{
public void onClick(View v)
{
convertButtonClicked();
}
};
private OnClickListener btnFeetListener = new OnClickListener()
{
public void onClick(View v)
{
btnCmClicked();
}
};
private void btnCmClicked()
{
// set the sender and the receiver of the intent
Intent intent = new Intent();
intent.setClass(getApplicationContext(), swin.examples.FeetToCmConvertor.class);
startActivity(intent); // transmit your intent
}
private void convertButtonClicked()
{
// set the sender and the receiver of the intent
Intent intent = new Intent();
intent.setClass(getApplicationContext(), swin.examples.TemperatureConvertor.class);
startActivity(intent); // transmit your intent
}
}
我想不出来,希望你能帮助我!提前谢谢你!编辑:代码更新,但仍然不能工作。如果有帮助,下面是日志消息:
[2013-04-20 22:44:20 - CombinedConvertor] Success!
[2013-04-20 22:44:21 - CombinedConvertor] Starting activity swin.examples.TemperatureConvertor on device emulator-5554

合适的IntentFilter
为主Activity
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
最奇怪的bug。对其他人都有用,但对我没用。重新制作温度转换器活动,它现在工作。谢谢大家的帮助!
