具有自定义样式的TextView导致奇怪的膨胀异常

Question

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="horizontal"
    android:layout_width="match_parent"
    android:layout_height="wrap_content">
    <TextView android:id="@+id/txtFirstOccurred"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        style="@style/CrashGroup"/>

    <TextView android:id="@+id/txtLastOccurred"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        style="@style/CrashGroup"/>
</LinearLayout>

<style name="CrashGroup">
        <item name="android:singleLine">false</item>
        <item name="android:textSize">@android:style/TextAppearance.Small</item>
        <item name="android:gravity">center_vertical</item>
    </style>

@Override
    public View getView(int position, View convertView, ViewGroup parent)
    {
        try
        {
            convertView = LayoutInflater.from(getContext()).inflate(R.layout.android_crash_group_layout, null);

            TextView txtFirstOccurred = (TextView)convertView.findViewById(R.id.txtFirstOccurred);
            txtFirstOccurred.setText(getItem(position).getFirstOccurred());

            TextView txtLastOccurred = (TextView)convertView.findViewById(R.id.txtLastOccurred);
            txtLastOccurred.setText(getItem(position).getLastOccurred());


            return convertView;
        }
        catch (Exception ex)
        {
            Log.e(TAG, ex.toString());
            return null;
        }
    }

我得到的错误是：

它似乎与样式有关，就像我从文本视图中删除这个样式属性一样，它似乎可以正常工作。

我认为您返回的convertView有时是null，因为处理convertView很棘手。

确保你有一个值。您可以使用smth如下：

 @Override
  public View getView(int position, View convertView, ViewGroup parent) {
    LayoutInflater inflater = (LayoutInflater) context
        .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    TextView text = null;

    if (convertView == null) {
      convertView = inflater.inflate(R.layout.listrow_details, null);
    }

    text = (TextView) convertView.findViewById(R.id.textView1);
    text.setText(children);

    return convertView;
  }

希望有帮助。
