片段
suggestion_list.setOnItemClickListener((parent, view, position, id) -> {
String selectedFromList = (String) (suggestion_list.getItemAtPosition(position));
showPreFilledData(selectedFromList);
Log.e(TAG, arraylist.get(position));
});
private void showPreFilledData(String string) {
final Dialog dialog = new Dialog(getActivity());
dialog.setContentView(R.layout.product_sales_layout);// error comes at this point
dialog.setTitle("Product Sales");
Button ok;
ok = (Button) dialog.findViewById(R.id.ok);
switch (string) {
case "A2A 100 MG TABS":
GolYgauge(55.1);
GolMgauge(32.9);
break;
case "AQUA-VIT SACHET":
GolYgauge(45.8);
GolMgauge(22.7);
break;
case "BRONCOPHYLINE SYRUP":
GolYgauge(65.7);
GolMgauge(42.4);
break;
}
ok.setOnClickListener(v -> dialog.dismiss());
Window window = dialog.getWindow();
window.setLayout(LinearLayout.LayoutParams.MATCH_PARENT, TableLayout.LayoutParams.MATCH_PARENT);
dialog.show();
}
当我在我的 list view
中单击一个项目时,我想打开一个布局并想在仪表内显示数据.但我收到错误
When I click on an item in my list view
I want to open a layout and want to display data inside a gauge. But I am getting error
android.view.InflateException:com.thumbsol.accuratemobileassetsmanagament:layout/product_sales_layout 中的二进制 XML 文件第 15 行:com.thumbsol.accuratemobileassetsmanagament:layout/product_sales_layout 中的二进制 XML 文件第 15 行:错误膨胀类
android.view.InflateException: Binary XML file line #15 in com.thumbsol.accuratemobileassetsmanagament:layout/product_sales_layout: Binary XML file line #15 in com.thumbsol.accuratemobileassetsmanagament:layout/product_sales_layout: Error inflating class
第 15 行是
The line number 15 is <com.highsoft.highcharts.core.HIChartView
. I am stuck to it. How can get rid from this issue?
任何帮助将不胜感激.
推荐答案
似乎是包装了Activity上下文的Dialog
类和库的HIChartView
无法处理的组合这个包装的上下文.我强制解开上下文,然后您的代码开始工作.如何:
Seems like a combination of Dialog
class wrapping the Activity context and the library's HIChartView
not able to process this wrapped context. I force-unwrapped the context and then your code started working. How to:
使用处理包装上下文的自定义实现扩展 HIChartView
:
Extend the HIChartView
with a custom implementation handling the wrapped context:
import android.app.Activity;
import android.content.Context;
import android.content.ContextWrapper;
import android.util.AttributeSet;
import com.highsoft.highcharts.core.HIChartView;
public class CustomHIChartView extends HIChartView {
public CustomHIChartView(Context context) {
super(unwrap(context));
}
public CustomHIChartView(Context context, AttributeSet attributeSet) {
super(unwrap(context), attributeSet);
}
// unwrap the context until I get the original passed-in Activity context
private static Activity unwrap(Context context) {
while (!(context instanceof Activity) && context instanceof ContextWrapper) {
context = ((ContextWrapper) context).getBaseContext();
}
return (Activity) context;
}
}
解包函数是从 https://stackoverflow.com/a/51640906/12321475 复制的,在那里你可以另请阅读为什么有时会包装基本上下文.
The unwrapping function is copied from https://stackoverflow.com/a/51640906/12321475, there you can also read on why the base context are sometimes being wrapped.
修改您的布局以使用自定义实现:
Modify your layout to use the custom implementation:
<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:padding="10dp"
android:scrollbars="none">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:padding="10dp">
<your.package.name.CustomHIChartView
android:id="@+id/goly_gauge"
android:layout_width="match_parent"
android:layout_height = "350dp"
/>
<your.package.name.CustomHIChartView
android:id="@+id/golm_gauge"
android:layout_width="match_parent"
android:layout_height="350dp"
/>
<Button
android:id="@+id/ok"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:text="OK" />
</LinearLayout>
</ScrollView>
