小编use*_*920的帖子

我有一个带有单个字符的textView(所有单个数字,数字0-9).我想在数字周围画一个圆圈或一个正方形.我看到一个线程提到使用九个补丁来围绕它,但我不确定如何做到这一点(或者如果它是最好的方法).我怎么能围绕数字圈？

谢谢

我有一个ExpandableListView,其中每个parentView都有一个EditText(和textview).当我将EditText添加到Layout时,它将不再允许我单击或展开ExpandableListView,所有焦点都转到EditText.有没有办法让EditText和ExpandableListView本身都可以点击？我希望能够单击expandableListView来展开列表,并且EditText能够输入文本.

谢谢

编辑:添加了我的组视图的代码

    public View getGroupView(int groupPosition, boolean isExpanded,
                             View convertView, ViewGroup parent) {

        if (convertView == null) {
            LayoutInflater inflater =  (LayoutInflater) myContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            convertView = inflater.inflate(R.layout.group_row, null);
        }

        TextView playerName = (TextView) convertView.findViewById(R.id.playerName);
        playerName.setText(groupElements[groupPosition]);
        final EditText holeScore = (EditText) convertView.findViewById(R.id.score);
        holeScore.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                Toast.makeText(scoreCard.this, "On CLick", Toast.LENGTH_SHORT).show();
                holeScore.setFocusable(true);
            }
        });
        return convertView;
    } 

我试图将相机放在Android手机上的纵向SurfaceView中.我使用http://developer.android.com/resources/samples/ApiDemos/src/com/example/android/apis/graphics/CameraPreview.html将相机放入surfaceView.然而,相机旋转90度,所以我尝试使用setDisplayOrientation(90)来修复它,但这会压缩图像(它可能没有正确调整SurfaceView的大小？).我该怎么做才能让相机不被挤压？

我正在尝试更改图形点的大小,但是当我执行mRenderer.setPointSize(size)时; 它永远不会改变..

这是我的图表的完整代码:

public class ShowGraph extends Activity {

    private XYMultipleSeriesDataset mDataset = new XYMultipleSeriesDataset();
    private XYMultipleSeriesRenderer mRenderer = new XYMultipleSeriesRenderer();
    private XYSeries mCurrentSeries;
    private XYSeriesRenderer mCurrentRenderer;
    private GraphicalView mChartView;
    int x,y;
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.graph_layout);
        LinearLayout layout = (LinearLayout) findViewById(R.id.chart);

        mRenderer.setPanLimits(new double[] { 00, 600 , 00, 300 });     //xmin,xmax,ymin,ymax  bars/grids limit
        mRenderer.setZoomLimits(new double[]{00, 200, 00, 30});     //xmin,xmax,ymin,ymax  zoom limit
        String seriesTitle = "Series " + …
