两款显卡在一个屏幕 [英] Two graphics in one screen

问题描述

我是想显示在一个屏幕上两个图形，但我不能。这里是code，其中我展示的onClick函数内部一个图形：

 情况下R.id.graphs：
            。GraphicalView mChartView =新需要等级（）执行（这一点）;
            的LinearLayout布局=（的LinearLayout）findViewById（R.id.graph）;
            layout.removeAllViews（）;
            layout.addView（mChartView，新的LayoutParams（LayoutParams.WRAP_CONTENT，LayoutParams.WRAP_CONTENT））;
            打破;
 

任何想法??

非常感谢你！

解决方案

 情况下R.id.graphs：
        。GraphicalView mChartView1 =新需要等级（）执行（这一点）;
        GraphicalView mChartView2 = //另一个chartView创作
        的LinearLayout布局=（的LinearLayout）findViewById（R.id.graph）;
        layout.removeAllViews（）;
        layout.addView（mChartView1，新的LayoutParams（LayoutParams.WRAP_CONTENT，LayoutParams.WRAP_CONTENT））;
        layout.addView（mChartView2，新的LayoutParams（LayoutParams.WRAP_CONTENT，LayoutParams.WRAP_CONTENT））;
        打破;
 

这应该工作。一定要对不同的ID的 mChartView - 如果你创建它们编程，而不是从XML布局充气，你需要设置id编程太：

  mChartView1.setId（1）;
mChartView2.setId（2）;
 

此外， RelativeLayout的可能会为您提供布局和为定位的长期更多的定制。然后，您需要设置在布局PARAMS的相对位置：

  RelativeLayout的布局=（RelativeLayout的）findViewById（R.id.graph）;
....
RelativeLayout.LayoutParams paramsForChart2 =新RelativeLayout.LayoutParams（ViewGroup.LayoutParams.WRAP_CONTENT，ViewGroup.LayoutParams.WRAP_CONTENT）;
paramsForChart2.addRule（RelativeLayout.RIGHT_OF，mChartView1.getId（））;
layout.addView（mChartView2，paramsForChart2）;
 

I've being trying to display two graphics in one screen but I'm not able. Here is the code where i show one graphic inside the onClick function:

case R.id.graphs:
            GraphicalView mChartView = new Niveau().execute(this);
            LinearLayout layout = (LinearLayout) findViewById(R.id.graph);
            layout.removeAllViews();
            layout.addView(mChartView, new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
            break;

Any idea??

Thank you very much!

解决方案

case R.id.graphs:
        GraphicalView mChartView1 = new Niveau().execute(this);
        GraphicalView mChartView2 = //  another chartView creation
        LinearLayout layout = (LinearLayout) findViewById(R.id.graph);
        layout.removeAllViews();
        layout.addView(mChartView1, new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
        layout.addView(mChartView2, new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
        break;

That should work. Be sure to have different ids on your mChartView - if you create them programmatically and not inflated from an XML layout, you need to set the id programmatically too:

mChartView1.setId(1);
mChartView2.setId(2);

Also, a RelativeLayout would probably offer you more customization in term of layout and positionning. You then need to set the relative positions in your layout params:

RelativeLayout layout = (RelativeLayout) findViewById(R.id.graph);
....
RelativeLayout.LayoutParams paramsForChart2 = new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT);
paramsForChart2.addRule(RelativeLayout.RIGHT_OF, mChartView1.getId());
layout.addView(mChartView2, paramsForChart2);
