和这里的编码主网页...............
and here coding of main page...............
public class firstpage extends Activity {
/** Called when the activity is first created. */
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.firstpage);
Button btnlenght=(Button)findViewById(R.id.btnlenght);
Button btnweight=(Button)findViewById(R.id.btnweight);
Button btnarea=(Button)findViewById(R.id.btnarea);
Button btntemperature=(Button)findViewById(R.id.btntemperature);
final ImageView handle=(ImageView)findViewById(R.id.handle);
ImageView back=(ImageView)findViewById(R.id.back);
SlidingDrawer slidingDrawer1=(SlidingDrawer)findViewById(R.id.slidingDrawer1);
slidingDrawer1.setOnDrawerOpenListener(new OnDrawerOpenListener() {
@Override
public void onDrawerOpened() {
// TODO Auto-generated method stub
handle.setImageResource(R.drawable.downarrow1);
}
});
slidingDrawer1.setOnDrawerCloseListener(new OnDrawerCloseListener() {
@Override
public void onDrawerClosed() {
// TODO Auto-generated method stub
handle.setImageResource(R.drawable.arrowup);
}
});
btnlenght.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
Intent n = new Intent(v.getContext(),lenght.class);
startActivity(n);
}
});
btnweight.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
Intent a = new Intent(v.getContext(),weight.class);
startActivity(a);
}
});
btnarea.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
Intent n = new Intent(v.getContext(),Area.class);
startActivity(n);
}
});
btntemperature.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
Intent n = new Intent(v.getContext(),temperature.class);
startActivity(n);
}
});
back.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
Intent n = new Intent(v.getContext(),A2ZunitconverterActivity.class);
startActivity(n);
finish();
System.exit(0);
}
});
}
}
推荐答案
声明所有你在标签内manifest文件调用为
Declare all the activity which you are calling in manifest file inside the tag as
<activity android:name=".temperature"/>
<activity android:name=".weight"/>
如果您使用不同的包这些类，那么你必须用包以声明
or if you use these classes in different package then you have to declare with the package as
<activity android:name="com.org.xxx.temperature">
<activity android:name="com.org.xxx.weight">
检查清单file..it可能对你有帮助...
check your manifest file..it may helpful to you...
