我有一个使用库MPAndroidChart的折线图
mChart.setData(data);
mChart.getAxisLeft().setTypeface(MyApplication.giloryItaly);
mChart.invalidate();
mChart.getXAxis().setTypeface(MyApplication.giloryItaly);
mChart.getAxisRight().setTypeface(MyApplication.giloryItaly);
问题是，AxisLeft即使使用，字体值也无法更改
mChart.getAxisLeft().setTypeface(MyApplication.giloryItaly);
但适用于 XAxis
任何解决方案如何改变字体类型的AxisLeft和AxisRight?

我已经下载了MPAndroidChart库来绘制LineChart,我注意到这个LineChart总是在yAxis上绘制xAxis,我需要在yAxis的底部绘制xAxis
这是我初始化图表的方式
mChart = (LineChart) findViewById(R.id.chart1);
mChart.setDescription("");
mChart.setNoDataTextDescription("You need to provide data for the chart.");
// enable value highlighting
mChart.setHighlightEnabled(true);
// enable touch gestures
mChart.setTouchEnabled(true);
mChart.setDragDecelerationFrictionCoef(0.9f);
// enable scaling and dragging
mChart.setDragEnabled(true);
mChart.setScaleEnabled(true);
mChart.setDrawGridBackground(false);
mChart.setHighlightPerDragEnabled(true);
mChart.setBackgroundColor(Color.WHITE);
XAxis xAxis = mChart.getXAxis();
xAxis.setDrawGridLines(false);
YAxis leftAxis = mChart.getAxisLeft();
leftAxis.setTextColor(ColorTemplate.getHoloBlue());
leftAxis.setAxisMaxValue(200f);
leftAxis.setDrawGridLines(false);
YAxis rightAxis = mChart.getAxisRight();
rightAxis.setDrawAxisLine(false);
rightAxis.setTextColor(Color.WHITE);
rightAxis.setDrawGridLines(false);
MyMarkerView mv = new MyMarkerView(this, R.layout.custom_marker_view);
// set the marker to the chart
mChart.setMarkerView(mv);
我有一个带有集合视图的应用程序和此集合视图中的一个单元格,可重定向到外部链接.
每当该链接打开时,应用程序在后台崩溃并提供调试器:
"由于内存问题而终止".
如果我只按主页按钮,应用程序继续正常工作.
if (UIDeviceOrientationIsLandscape([UIDevice currentDevice].orientation)) Portrait = NO;
else if (UIDeviceOrientationIsPortrait([UIDevice currentDevice].orientation)) Portrait = YES;
else Portrait = [self getStatusBarOrientations];
if(indexPath.row == 4 && indexPath.section == 0)
{
NewsListCell *cell = [collectionView dequeueReusableCellWithReuseIdentifier:@"Cell4" forIndexPath:indexPath];
if ([languageID isEqualToString:@"1025"])
{
cell.title.text =[NSString stringWithFormat:@"????? ????? %@", [self.pdfCoverDict valueForKey:@"PdfDate"]];
[cell.contentView setTransform:CGAffineTransformMakeScale(-1, 1)];
} else {
cell.title.text =[NSString stringWithFormat:@"Today's Edition %@", [self.pdfCoverDict valueForKey:@"PdfDate"]];
}
NSURL *imageUrl = [NSURL URLWithString:[self.pdfCoverDict valueForKey:@"CoverImage"]];
[cell.imageView sd_setImageWithURL:imageUrl];
cell.imageViewWidth.constant = Portrait ? 246 : 331;
cell.imageViewHeight.constant = Portrait ? …我有一套用于我的热敏打印机的命令:这是一个例子
ASCII ESC a n
Decimal 27 97 n
Hexadecimal 1B 61 n
Description Default is 0
0 ? m ? 2 or 48 ? m ? 50
Align left: n=0,48
Align middle: n=1,49
Align right: n=2,50
我想知道如何使用这个命令?? 我知道我需要像这样写入打印机命令:
byte [] cmd = new byte[3];
cmd[0]=??
cmd[1]???
mmOutputStream.write(cmd);//out put stream of soccket connected to
//printer by bluetooth
有关更多说明:我想向我的打印机添加命令以使文本显示在中心
