Viewpager로 세개의 버튼과 xml을 뿌려주고
xml에 graphview를 사용하여 라인그래프를 그려보고 싶은데요
graphview에 대한 activity를 생성해서 몇개의 샘플데이터를 써서 그래프가 그려지는지 확인해보려고 하는데
액티비티가 연결이 안되는거같아요 ..
지금 모습인데요 그래프가 생성만 되고 데이터가 들어가질 않아서요 ...
따로 돌려보면 문제없이 잘 되는데 viewpager랑 같이 쓰려고 하니까 액티비티 간의 연결이 안된건가요 ?
도와주세요
viewpager부분 코드입니다.
public class chartActivity extends AppCompatActivity {
ViewPager pager;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.chartmain);
pager = (ViewPager)findViewById(R.id.pager);
CustomAdapter adapter = new CustomAdapter(getLayoutInflater());
pager.setAdapter(adapter);
}
public void vpClick(View v) {
int position;
switch (v.getId()) {
case R.id.btn_day:
setCurrentInfalteItem(0);
break;
case R.id.btn_week:
setCurrentInfalteItem(1);
break;
case R.id.btn_month:
setCurrentInfalteItem(2);
break;
}
}
private void setCurrentInfalteItem(int type) {
if(type==0){
pager.setCurrentItem(0);
}else if (type ==1){
pager.setCurrentItem(1);
}else if (type ==2){
pager.setCurrentItem(2);
}
}
private Button inbtn_day;
private Button inbtn_week;
private Button inbtn_month;
private void setlayout(){
inbtn_day = (Button)findViewById(R.id.btn_day);
inbtn_week = (Button)findViewById(R.id.btn_week);
inbtn_month = (Button)findViewById(R.id.btn_month);
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}
어댑터 부분 입니다.
public class CustomAdapter extends PagerAdapter {
LayoutInflater inflater;
public CustomAdapter(LayoutInflater inflater){
this.inflater = inflater;
}
@Override
public int getCount() {
return 3;
}
@Override
public Object instantiateItem(ViewGroup container, int position) {
View view = null;
if(position==0)
{
view = inflater.inflate(R.layout.viewpager1,null);
view.findViewById(R.id.btn_day);
}else if(position==1) {
view = inflater.inflate(R.layout.viewpager2,null);
view.findViewById(R.id.btn_week);
}else {
view = inflater.inflate(R.layout.viewpager3,null);
view.findViewById(R.id.btn_month);
}
container.addView(view);
return view;
}
@Override
public void destroyItem(ViewGroup container, int position, Object object) {
container.removeView((View)object);
}
@Override
public boolean isViewFromObject(View v, Object obj) {
return v==obj;
}
}
그래프를 그려줄 액티비티 입니다.
public class chart_dayActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.viewpager1);
Log.d("1", "GraphView running test");
GraphView chart_day_line = (GraphView)findViewById(R.id.chart_day);
LineGraphSeries<DataPoint> line_series =
new LineGraphSeries<DataPoint>(new DataPoint[]{
new DataPoint(0,1),
new DataPoint(1,4),
new DataPoint(2,2),
new DataPoint(3,5),
new DataPoint(4,3)
});
chart_day_line.addSeries(line_series);
Log.d("1", "GraphView running test");
Viewport viewport = chart_day_line.getViewport();
viewport.setXAxisBoundsManual(true);
viewport.setYAxisBoundsManual(true);
viewport.setMinX(0);
viewport.setMaxX(5);
viewport.setMinY(0);
viewport.setMaxY(5);
viewport.setScrollable(true);
}
}
xml입니다
