Question

我正在开发一个Android应用程序，我创建了2个片段（FragmentA，FragmentB）我还有片段活动的适配器和mymain类。问题是我想在我的2个操作栏活动（表格和饼图）中用我收到的webservices数据填充这2个片段。如何将以下饼图转换为片段活动？

public class PieChartActivity extends Details implements OnSeekBarChangeListener,OnChartValueSelectedListener {
    private PieChart mChart;
    private SeekBar mSeekBarX, mSeekBarY;
    private TextView tvX, tvY;

    private Typeface tf;


    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
                WindowManager.LayoutParams.FLAG_FULLSCREEN);
        setContentView(R.layout.activity_piechart);

        mSeekBarX = (SeekBar) findViewById(R.id.sbPieChart);
        mSeekBarY = (SeekBar) findViewById(R.id.seekBar2);
        mSeekBarY.setProgress(10);


        mSeekBarX.setOnSeekBarChangeListener(this);
        mSeekBarY.setOnSeekBarChangeListener(this);

        mChart = (PieChart) findViewById(R.id.chart1);
        mChart.setUsePercentValues(true);

        // change the color of the center-hole
        // mChart.setHoleColor(Color.rgb(235, 235, 235));
        mChart.setHoleColorTransparent(true);

        tf = Typeface.createFromAsset(getAssets(), "OpenSans-Regular.ttf");

        mChart.setCenterTextTypeface(Typeface.createFromAsset(getAssets(), "OpenSans-Light.ttf"));

        mChart.setHoleRadius(60f);
        mChart.setDescription("");
        mChart.setDrawCenterText(true);
        mChart.setDrawHoleEnabled(true);
        mChart.setRotationAngle(0);

        // enable rotation of the chart by touch
        mChart.setRotationEnabled(true);

        // mChart.setUnit(" €");
        // mChart.setDrawUnitsInChart(true);

        // add a selection listener
        mChart.setOnChartValueSelectedListener(this);
        // mChart.setTouchEnabled(false);

        mChart.setCenterText("MPAndroidChart\nLibrary");

        setData(3, 100);

        mChart.animateXY(1500, 1500);
        // mChart.spin(2000, 0, 360);

        Legend l = mChart.getLegend();
        l.setPosition(LegendPosition.RIGHT_OF_CHART);
        l.setXEntrySpace(7f);
        l.setYEntrySpace(5f);
    }

@arual您可以通过将Activity类转换为ActionbarActivity类来实现此目的。

((ActionBarActivity)getActivity()).getSupportActionBar();

从Fragment调用ActionBarActivity
