<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"

    ImageView imageView = new ImageView(mContext);
    imageView.setImageResource(mThumbIds[position]);

    setContentView(R.layout.grid_layout);

    GridView gridView = (GridView) findViewById(R.id.grid_view);

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

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

            startActivity(i);
        }
    });
}

启动活动后，只显示不同的布局。只是ImageView和TextView。第一个editText1在gridView下无用。把它放在不同的布局中。

如何在GRIDVIEW中单击图像然后从EditText中显示名称，从GridView名称中显示NOT
