GridViewActivity.java

GridViewActivity.java

    public class GridViewActivity extends Activity {

        GridView gridView;

        static final String[] numbers = new String[] { 
                "A", "B", "C", "D", "E",
                "F", "G", "H", "I", "J",
                "K", "L", "M", "N", "O",
                "P", "Q", "R", "S", "T",
                "U", "V", "W", "X", "Y", "Z"};

        @Override
        public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);

            setContentView(R.layout.main);

            gridView = (GridView) findViewById(R.id.gridView1);

            ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
                    android.R.layout.simple_list_item_1, numbers);

            gridView.setAdapter(adapter);

            gridView.setOnItemClickListener(new OnItemClickListener() {
                public void onItemClick(AdapterView<?> parent, View v, int position, long id) {
                   Intent intent = null;
                   intent = new Intent(getApplicationContext(), ListActivity.class);
                   // Send the position to the next activity
                   // i.e. position 0 -> numbers[0] -> "A"
                   intent.putExtra("PositionToList", position);
                   startActivity(intent);
                }
            });

        }

    }

ListActivity.java

ListActivity.java

public class ListActivity extends Activity {

    // Dummy array, Only for example purposes!!! 
    // In real life you will fetch data from somewhere else (i.e. DB, file, resources, network)
    static final String[][] list = new String[][] { 
                {"Abhay", "Ajay", "Arun"},
                {"Brahmaiah", "bharth", "bhargav"},
                ....,
                ....,
                ....};

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        // Get the position in order to know the data to be displayed
        Intent intent = getIntent();
        int position = intent.getIntExtra("PositionToList", 0); // here 0 is the default value

        // Set the content to display in your adapter
        ArrayAdapter<String> myAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, list[position]);
        ListView myList = (ListView)findViewById(R.id.listView);
        myList.setAdapter(myAdapter);
    }
}

重要提示
真正的问题在这里展示的是不是code本身（我没有检查它是否编译顺便说一句），但如何与其他交流活动的想法。

Important The real point to show here is not the code itself (I didn't check if it compiles btw) but the idea of how to communicate with other activities.

1. 首先，你要选择你的GridActivity的东西，然后根据你想显示在你的下一个活动的正确内容选择。这是使用的意图完成

二，基于你作出决定你对ListActivity的previous活动传递的信息是什么，以及如何显示内容。

Second, based on the information passed by the previous activity you take decisions in your ListActivity about what and how to display the content.
