말씀해주신데로
Context context, AttributeSet attrs
이것들 추가도 해보고 했는데 안되더라구요
컴파일상에서도 에러는 안뜨는데
로그켓 에러를 보면

이게 문제인거 같은데
전에 답변주셨던것처럼
Context context, AttributeSet attrs 다 추가하고 해봤는데도 저렇게 뜨네요;;
로그켓을 보고 에러를 확실하게 볼정도의 실력이 안되는지라;;
소스도 같이 올려봅니다
먼저 메인입니다
package exam.monami153;
import android.app.*;
import android.os.*;
import android.view.*;
import android.widget.Button;
public class monami153 extends Activity {
View mMain, mSub, mHow;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
mMain = findViewById(R.id.mainpage);
mSub = findViewById(R.id.sub);
mHow = findViewById(R.id.how);
findViewById(R.id.Calcul).setOnClickListener(ClickListener);
findViewById(R.id.How).setOnClickListener(ClickListener);
findViewById(R.id.Exit).setOnClickListener(ClickListener);
findViewById(R.id.Calcul).setOnClickListener(ClickListener);
findViewById(R.id.Clear).setOnClickListener(ClickListener);
findViewById(R.id.Back).setOnClickListener(ClickListener);
findViewById(R.id.backm).setOnClickListener(ClickListener);
}
Button.OnClickListener ClickListener = new Button.OnClickListener() {
public void onClick(View v) {
mMain.setVisibility(View.INVISIBLE);
mSub.setVisibility(View.INVISIBLE);
mHow.setVisibility(View.INVISIBLE);
switch (v.getId()) {
case R.id.Calcul:
mSub.setVisibility(View.VISIBLE);
break;
case R.id.Clear:
onResume();
mSub.setVisibility(View.VISIBLE);
break;
case R.id.Back:
mSub.setVisibility(View.INVISIBLE);
mMain.setVisibility(View.VISIBLE);
break;
case R.id.How:
mHow.setVisibility(View.VISIBLE);
break;
case R.id.backm:
mHow.setVisibility(View.INVISIBLE);
mMain.setVisibility(View.VISIBLE);
break;
case R.id.Exit:
finish();
}
}
};
}
프리라인은 책에 나온걸 그대로 가져와봤습니다
package exam.monami153;
import java.util.*;
import android.app.*;

import android.graphics.*;

public class FreeLine extends Activity {

private MyView vw;
ArrayList<Vertex> arVertex;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
vw = new MyView(this);
setContentView(vw);
arVertex = new ArrayList<Vertex>();
}
public class Vertex {
Vertex(float ax, float ay, boolean ad) {
x = ax;
y = ay;
Draw = ad;
}
float x;
float y;
boolean Draw;
}
protected class MyView extends View {

public MyView(Context context, AttributeSet attrs, int defSytle) {
super(context, attrs, defSytle);
}
public MyView(Context context, AttributeSet attrs) {

}
public MyView(Context context) {
super(context);
mPaint = new Paint();
mPaint.setColor(Color.BLACK);
mPaint.setStrokeWidth(3);
mPaint.setAntiAlias(true);
}
public void onDraw(Canvas canvas) {
canvas.drawColor(0xffe0e0e0);
for (int i=0;i<arVertex.size();i++) {
if (arVertex.get(i).Draw) {
canvas.drawLine(arVertex.get(i-1).x, arVertex.get(i-1).y,
arVertex.get(i).x, arVertex.get(i).y, mPaint);
}
}
}
public boolean onTouchEvent(MotionEvent event) {
if (event.getAction() == MotionEvent.ACTION_DOWN) {
arVertex.add(new Vertex(event.getX(), event.getY(), false));
return true;
}
if (event.getAction() == MotionEvent.ACTION_MOVE) {
arVertex.add(new Vertex(event.getX(), event.getY(), true));
invalidate();
return true;
}
return false;
}
}
}

메인페스트에 프리라인 추가도 해놨구요
제발좀 가르침좀 내려주시길..........
혹시 몰라서 파일채로 압축해서 같이 올립니다
<View class="exam.monami153.FreeLine$MyView" android:id="@+id/MyView" android:layout_width="fill_parent" android:layout_height="fill_parent" />로 수정하세요. 이너클래스의 $ 는 안드로이드 내부 XML 파서가 제대로 인식하지 못합니다.
