我遇到了問題。我想用一個按鈕打開一個Activity,但它總是崩潰。 所以我創建了2個類和一個按鈕。但它不斷崩潰。按鈕開始活動Android
- 類是activity_home class(),其次是schedule_act()類。
activity_home類:
package my.action.bat;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
public class activity_home extends Activity {
private Button ScheduleBtn;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
ScheduleBtn = (Button) findViewById(R.id.home_btn_schedule);
ScheduleBtn.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// TODO Auto-generated method stub
Intent myIntent = new Intent("my.action.bat.schedule_act");
startActivity(myIntent);
}
});
}
}
schedule_act類:
package my.action.bat;
import android.app.Activity;
import android.os.Bundle;
public class schedule_act extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.schedule_layout);
}
}
Android清單:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="my.action.bat"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk android:minSdkVersion="8" />
<application
android:icon="@drawable/ic_launcher"
android:label="@string/app_name" >
<activity
android:label="@string/app_name"
android:name=".activity_home" >
<intent-filter >
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:label="@string/app_name"
android:name=".schedule_act" >
<intent-filter >
<action android:name="my.action.bat.SCHEDULE_ACT" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
</application>
</manifest>
非常感謝。
