动态膨胀给我一个nullexception [英] Dynamic inflating gives me a nullexception
问题描述
我正在使用LinearLayout进行布局.此布局将在内部填充另一个布局.目前,我遇到了问题(nullexceptions).下一个是我的膨胀代码:
I'm making a layout with a LinearLayout. This layout will have another layout inflated inside. Currently, I'm getting problems (nullexceptions) with that. My inflating code is the next:
private void addLayoutInvoices() {
LinearLayout ll_invoices = new LinearLayout(getActivity());
ll_invoices.setGravity(Gravity.CENTER);
ll_invoices.setOrientation(LinearLayout.VERTICAL);
LinearLayout.LayoutParams llp = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT);
ll_invoices.setLayoutParams(llp);
...
if(mas.size() > 0) {
for (int i = 0; i < mas.size(); i++) {
if(mas.get(i).getStatus() == 1){
View newGratLayout = LayoutInflater.from(getActivity()).inflate(R.layout.albaran_invoices_row, ll_invoices_layer, false);
newGratLayout.setId(i + 8000);
RelativeLayout rl_albaran_invoices_row = (RelativeLayout) newGratLayout.findViewById(R.id.rl_albaran_invoices_row);
final LinearLayout ll_details = (LinearLayout) newGratLayout.findViewById(R.id.ll_details);
...
rl_albaran_invoices_row.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if (!rowClicked) {
ll_details.setVisibility(View.VISIBLE);
rowClicked = true;
} else {
ll_details.setVisibility(View.GONE);
rowClicked = false;
}
}
});
ll_invoices.addView(newGratLayout);
}
}
ll_invoices_layer.addView(ll_invoices);
if(existsPending)
bt_resend_pending.setVisibility(View.VISIBLE);
}
}
albaran_invoices_row.xml
albaran_invoices_row.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="@+id/rl_albaran_invoices_row"
android:scrollIndicators="none">
...
</RelativeLayout>
logcat在 rl_albaran_invoices_row.setOnClickListener ... 行中显示错误NullPointerException.我在做什么错了?
The logcat shows an error NullPointerException in the line rl_albaran_invoices_row.setOnClickListener.... What I'm doing wrong?
注意:我正在从片段中执行此操作.
NOTE: I'm doing this from a Fragment.
推荐答案
我更改了视图类型以解决此问题:
I've change the type of view to resolve the problem:
我有...
//View newGratLayout = LayoutInflater.from(getActivity()).inflate(R.layout.albaran_invoices_row, ll_invoices_layer, false);
现在我有...
RelativeLayout newGratLayout = (RelativeLayout)getActivity().getLayoutInflater().inflate(R.layout.albaran_invoices_row, null); //rl_albaran_invoices_row
感谢人们如何尝试帮助我.
