获取要在 EditText 上显示的 GridView 的图像源名称

Question

请帮我解决我的问题，获取要在 EditText Android 上显示的 GridView 的图像源名称。如果单击 imageview 然后在 EditText android 中显示名称图像 .. 在图像名称之前从资源名称中提取而不是来自 GridView 中已经存在的资源..！

此视图图像说明：

grid_view：

 <?xml version="1.0" encoding="utf-8"?>
 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
 android:layout_width="fill_parent"
 android:layout_height="fill_parent"
 android:orientation="vertical">


 <GridView
 android:id="@+id/grid_view"
 android:layout_width="fill_parent"
 android:layout_height="368dp"
 android:columnWidth="90dp"
 android:gravity="center"
 android:horizontalSpacing="10dp"
 android:numColumns="auto_fit"
 android:stretchMode="columnWidth"
 android:verticalSpacing="10dp"/>


 <EditText
 android:id="@+id/editText1"
 android:layout_width="match_parent"
 android:layout_height="wrap_content"
 android:ems="10"
 android:inputType="text" />

 </LinearLayout>

字符串.xml

 <?xml version="1.0" encoding="utf-8"?>
 <resources>

     <string name="app_name">Tes Buta Warna</string>
     <string name="action_settings">Settings</string>
     <string name="hello_world">Hello world!</string>
     <string name="inputdata">INPUT DATA</string>

return imageView;

gridView.setOnItemClickListener(new OnItemClickListener() {
    @Override
    public void onItemClick(AdapterView<?> parent, View v,
            int position, long id) {

        // Sending image id to FullScreenActivity
        Intent i = new Intent(getApplicationContext(), Training.class);
        // passing array index
        i.putExtra("id", position);

        startActivity(i);
    }

您需要定义与您的可绘制对象名称相同的字符串数组。

/res/values/string.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
  <string-array
    name="string_array_name">
    <item>Edwin</item>
    <item>Yulius</item>
    <item>Natan</item>
    <item>Ria</item>
  </string-array>
</resources>

在您的代码中

String[] names = getResource().getStringArray(R.array.string_array_name);

// you must implement this class
YourAdapter adapter = new YourAdapter(names, /* and some params */);
youGridView.setAdapter(adapter);

YouAdapter.java（扩展 android.widget.ArrayAdapter）

@override
public View getView(int position, View convertView, ViewGroup parent) {

  // you must inflate gridview' child layout
  View view = layoutInflater.inflate( ... );
  ImageView imageView = (ImageView) view.findViewById( ... );
  TextView imageView = (TextView) view.findViewById( ... );

  // ...

  String name = getItem();
  int id = getIdentifier(name, "drawable", getApplicationInfo().packageName);

  imageView.setImageResource(id);
  textView.setText(name);
}

这仅在您的所有图像都在资源目录中时才有效。
