请帮助我解决我的问题，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从GridView中已经存在...！

此视图图片ilustration：

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"

 </LinearLayout>

的strings.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>

            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drawable相同名称的字符串数组。

/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>

代码

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);
}

这仅在所有图像都在资源目录中时才有效。
