You can set height and width like this:

<pre><code>myGraphView.setLayoutParams(new LayoutParams(width, height));
</code></pre>

blocks|key|997327|text|如果您知道视图的确切大小，只需使用setLayoutParams()|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|997328|graphView.setLayoutParams(new+LayoutParams(width,+height));|code-block|syntax|javascript|997329|或者在Kotlin中：|997330|graphView.layoutParams+=+LayoutParams(width,+height)|997331|但是，如果需要更灵活的方法，可以根据可用空间和布局约束(wrap_content、match_parent或固定大小)覆盖onMeasure()以更精确地测量视图。您可以在android+docs中找到有关onMeasure()的更多详细信息。|997332|entityMap|0|LINK|mutability|MUTABLE|url|http://developer.android.com/guide/topics/ui/custom-components.html#custom^0|H|H|0|0|0|0|S|C|15|C|1P|B|2V|B|2E|C|0|0^^$0|@$1|2|3|4|5|6|7|Y|8|@$9|Z|A|10|B|C]]|D|@]|E|$]]|$1|F|3|G|5|H|7|11|8|@]|D|@]|E|$I|J]]|$1|K|3|L|5|6|7|12|8|@]|D|@]|E|$]]|$1|M|3|N|5|H|7|13|8|@]|D|@]|E|$I|J]]|$1|O|3|P|5|6|7|14|8|@$9|15|A|16|B|C]|$9|17|A|18|B|C]|$9|19|A|1A|B|C]|$9|1B|A|1C|B|C]]|D|@$9|1D|A|1E|1|1F]]|E|$]]|$1|Q|3|-4|5|6|7|1G|8|@]|D|@]|E|$]]]|R|$S|$5|T|U|V|E|$W|X]]]]

If you know the exact size of the view, just use <code>setLayoutParams()</code>:
<pre><code>graphView.setLayoutParams(new LayoutParams(width, height));
</code></pre>
Or in Kotlin:
<pre><code>graphView.layoutParams = LayoutParams(width, height)
</code></pre>
However, if you need a more flexible approach you can override <code>onMeasure()</code> to measure the view more precisely depending on the space available and layout constraints (<code>wrap_content</code>, <code>match_parent</code>, or a fixed size). You can find more details about <code>onMeasure()</code> in the <a href="http://developer.android.com/guide/topics/ui/custom-components.html#custom" rel="noreferrer">android docs</a>.

blocks|key|783068|text|可以在相对布局中设置视图的高度和宽度，如下所示|type|unstyled|depth|inlineStyleRanges|entityRanges|data|783069|ViewGroup.LayoutParams+params+=+view.getLayoutParams();
params.height+=+130;
view.setLayoutParams(params);|code-block|syntax|javascript|783070|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

you can set the height and width of a view in a relative layout like this 

<pre><code>ViewGroup.LayoutParams params = view.getLayoutParams();
params.height = 130;
view.setLayoutParams(params);
</code></pre>

blocks|key|783146|text|这是一个基于Kotlin的版本，假设父视图是LinearLayout的一个实例。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|783147|someView.layoutParams+=+LinearLayout.LayoutParams(100,+200)|code-block|syntax|javascript|783148|这允许在一行中设置宽度和高度(100和200)。|783149|entityMap^0|M|C|0|0|F|3|J|3|0^^$0|@$1|2|3|4|5|6|7|O|8|@$9|P|A|Q|B|C]]|D|@]|E|$]]|$1|F|3|G|5|H|7|R|8|@]|D|@]|E|$I|J]]|$1|K|3|L|5|6|7|S|8|@$9|T|A|U|B|C]|$9|V|A|W|B|C]]|D|@]|E|$]]|$1|M|3|-4|5|6|7|X|8|@]|D|@]|E|$]]]|N|$]]

This is a Kotlin based version, assuming that the parent view is an instance of <code>LinearLayout</code>.

<pre><code>someView.layoutParams = LinearLayout.LayoutParams(100, 200)
</code></pre>

This allows to set the width and height (<code>100</code> and <code>200</code>) in a single line.

blocks|key|783166|text|在Kotlin上，您可以使用其虚拟属性直接设置任何视图的宽度和高度：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|783167|someView.layoutParams.width+=+100
someView.layoutParams.height+=+200|code-block|syntax|javascript|783168|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

On Kotlin you can set width and height of any view directly using their virtual properties:

<pre><code>someView.layoutParams.width = 100
someView.layoutParams.height = 200
</code></pre>

blocks|key|997564|text|如果你使用Kotlin，你也可以使用下面的代码，将你给定的lambda应用到当前的布局参数上：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|997565|someView.updateLayoutParams+{
++++height+=+200
}|code-block|syntax|javascript|997566|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

If you're using Kotlin, you can also use the following code which applies your given lambda on the current layout params:
<pre class="lang-kotlin prettyprint-override"><code>someView.updateLayoutParams {
 height = 200
}
</code></pre>

I have created a custom view named <code>Graphview</code> . Here is the structure for the GraphView class.

<pre><code>public class GraphView extends View {

 public GraphView(Context context, float[] values, String title, String[] horlabels, String[] verlabels, boolean type) {
 super(context);
 ........
 }

 ..................
 .................
}
</code></pre>

I have added the view in a tablerow using <code>addview()</code>. It is working fine. Now I want to set height and width for the <code>GraphView</code>. How to do that?

Android set height and width of Custom view programmatically

Kotlin

我已经创建了一个名为Graphview的自定义视图。下面是GraphView类的结构。public class GraphView extends View {    public GraphView(Context context, float[] values, String title, String[] hor...
