基本的gridview android问题。它没有显示任何东西 我现在正在制作一个带有自定义布局的基本GRIDVIEW。虽然我现在只在gridview中显示文本。我在网上学习了一些教程，一步一步地学习，我没有从android studio得到任何错误，我运行了它。但当我运行它时，它只显示一个空白的白色页面。这次我确实初始化了适配器，但它仍然没有显示任何内容。救命啊，我错过了什么

activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="horizontal"
    tools:context=".MainActivity">

    <TextView
        android:id="@+id/firsttext"
        android:layout_width="match_parent"
        android:layout_height="@dimen/ButtonSize"
        android:text="@string/hello"
        android:gravity="center"/>
    <GridView
        android:layout_below="@+id/firsttext"
        android:id="@+id/firstList"
        android:layout_width="match_parent"
        android:layout_height="200dp"
        android:columnWidth="100dp"
        android:numColumns="auto_fit"
        android:stretchMode="columnWidth">
    </GridView>

</RelativeLayout>

MainActivity.java

public class MainActivity extends AppCompatActivity {


    String[] Names = {"great","good","average","great","good","average","great","good","average","great","good","average","great","good","average","great","good","average"};
    GridView grid;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        grid = (GridView)findViewById(R.id.firstList);

        gridAdapter adapter = new gridAdapter(this,Names);
        grid.setAdapter(adapter);

    }


}

以后使用RecyclerView而不是GridView。您的问题是设置TextView的颜色，请选中以将textColor设置为黑色

将此行更改为：在gridadapter中：

if (convertView == null) {
        layoutInflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        gridView = layoutInflater.inflate(R.layout.gridlist, parent, false); 
}

不要在网格列表中使用

match\u parent

和

TextView

的

layout\u heith

通过

wrap\u content

回复，并为

TextView

设置除白色以外的特殊颜色。

在适配器中更改此：

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        convertView= layoutInflater.inflate(R.layout.gridlist,null);
        TextView textView = (TextView)convertView.findViewById(R.id.gridtext);
        textView.setText(names[position]);
        return convertView;
    }

是的，我把它换成了黑色。还是一样的结果还是给我一个空白哦，顺便问一下，你还有黑色的文本颜色吗？否则..嗯，我再也没有想法了，试着按照本教程进行操作：特别检查适配器中的适配器和getView方法：

if (convertView == null) {
        layoutInflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        gridView = layoutInflater.inflate(R.layout.gridlist, parent, false); 
}

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        convertView= layoutInflater.inflate(R.layout.gridlist,null);
        TextView textView = (TextView)convertView.findViewById(R.id.gridtext);
        textView.setText(names[position]);
        return convertView;
    }
