我创建了从控件扩展的自定义视图控件View
,仅在方法中绘制了一些信息onDraw
。
如果我在常规活动布局上创建控件,一切正常。但是,如果我在 Fragment 中创建此控件onCreateView()
,它会在创建时进行绘制,然后我的视图“冻结”。它可以工作并解决但不调用onDraw()
. 我想打电话invalidate()
,但什么也没有。
有任何想法吗?
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
final View v = inflater.inflate(R.layout.button, container, false);
mAgatButton = (agatButton) v.findViewById(R.id.agatButton1);
mAgatButton.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View view) {
// This not Repainted
final GraphViewSeries TahoSer = mGraphTaho.getSeries((byte)0);
mGraphTahoPos++;
TahoSer.appendData(new GraphViewData(mGraphTahoPos, 50d), true);
//This Work correct
mTahoLabel.setText(String.format(getString(R.string.button_rpm), (int)(Math.random()*1000)));
Log.d(agatButton.class.toString(),"Click Detected: "+TahoSer.size());
}
});
final Context context = getActivity().getApplicationContext();
LinearLayout graphView = (LinearLayout) v.findViewById(R.id.graph_lay_taho);
graphView.addView(mGraphTaho = getGraphView(context,"Taho"));
mTahoLabel = (TextView) v.findViewById(R.id.tahoText);
mTahoLabel.setText(String.format(getString(R.string.button_rpm), 0));
return v;
}
private GraphView getGraphView(Context context, String Name)
{
final GraphView tmpView = new LineGraphView(context,Name);
tmpView.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT,LayoutParams.MATCH_PARENT));
List<GraphViewData> initalSeriesData = new ArrayList<GraphViewData>();
for (byte i=0;i<20;i++)
initalSeriesData.add(new GraphViewData(i, 0d));
final GraphViewSeries tahoSeries = new GraphViewSeries(initalSeriesData);
((LineGraphView) tmpView).setDrawBackground(true);
tmpView.addSeries(tahoSeries);
tmpView.setViewPort(1, 20);
tmpView.setScalable(false);
tmpView.setManualYAxis(true);
tmpView.setManualYAxisBounds(100, 0);
return tmpView;
}
如果我不使用 Fragment 一切正常。怎么了?
