Question

我试图从4小时内解决问题，但找不到答案

这是Grid_dif

public class Grid_dif extends BaseAdapter {
Integer []image_grid2;

Context c;
LayoutInflater inflater;

public Grid_dif( Application applicationContext,Integer[] image_grid2) {
    this.image_grid2 = image_grid2;
    this.c = applicationContext;
    inflater=(LayoutInflater.from(applicationContext));
}

@Override
public int getCount() {
    return image_grid2.length;
}

@Override
public Object getItem(int position) {
    return image_grid2[position];
}

@Override
public long getItemId(int position) {
    return position;
}

@SuppressLint("ViewHolder")
@Override
public View getView(int position, View view, ViewGroup parent) {
    view=inflater.inflate(R.layout.grid_item2,null);
    ImageView image_g=view.findViewById(R.id.image_grid2);
    image_g.setImageResource(image_grid2[position]);
    return view;
}

}

网格item2.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:background="#fff"

    android:layout_height="match_parent">
    <ImageView
        android:layout_width="270dp"
        android:layout_height="150dp"
        android:id="@+id/image_grid2"
        android:src="@drawable/image"
    />

</RelativeLayout>

这是错误

您的充气机未初始化。将您的getView（..）方法替换为：

public View getView(int position, View view, ViewGroup parent) {
   if(inflater==null)
     inflater = LayoutInflater.from(this.c);

    //it is also unnecessary to reinitialize the view everytime this callback is called. Take advantage of recycling feature of the list.
    if(view ==null)
      view = inflater.inflate(R.layout.grid_item2,null);

    ImageView image_g=view.findViewById(R.id.image_grid2);
    image_g.setImageResource(image_grid2[position]);
    return view;
}

另外，请检查您在构造函数上传递的上下文的类型，它应该是使用适配器的活动，或者如果是其片段，则传递片段getActivity（）覆盖。

活动：

new Grid_dif(MyActivity.this, ..);

片段：

new Grid_dif(this.getActivity(), ..)

在Android.view.inflateexception二进制XML文件中停止了该应用程序
