获得焦点有现成方法

上下左右移动根据消息机制实现

switch()
{
case:
}

代码如下：





public class AllAppsActivity extends Activity {

    /** Called when the activity is first created. */

	private final int WC = ViewGroup.LayoutParams.WRAP_CONTENT;

	private final int FP = ViewGroup.LayoutParams.FILL_PARENT;

	

	private LayoutInflater mInflater;

	private TableLayout applicationLayout;

    @Override

    public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.main);

        

        applicationLayout = (TableLayout)findViewById(R.id.applicationLayout);     

        //全部列自动填充空白处

        applicationLayout.setStretchAllColumns(true);

        mInflater = this.getLayoutInflater();//LayoutInflater.from(this);



        List<PackageInfo> packageInfos = this.getPackageManager().getInstalledPackages(0);

		for (int row = 0; row < (packageInfos.size() / 5 + 1); row++) {

			TableRow tableRow = new TableRow(this);

			for (int col = 0; col < 5; col++) {

				int i = row * 5 + col;

				if (i < packageInfos.size()) {

					PackageInfo info = packageInfos.get(i);

					View view = new View(this);

					view = mInflater.inflate(R.layout.application_list, null,false);

					TextView name = (TextView) view.findViewById(R.id.name);

					ImageView imageView = (ImageView) view

							.findViewById(R.id.icon);

					name.setText(info.applicationInfo.loadLabel(

							this.getPackageManager()).toString());

					imageView.setBackgroundDrawable((info.applicationInfo

							.loadIcon(this.getPackageManager())));

					// applicationLayout.addView();

					view.setPadding(0, 15, 0, 0);

					view.setTag("colView:"+i);

					view.setClickable(true);

					view.setFocusable(true);

					tableRow.addView(view);

				}



			}

			// 新建的TableRow添加到TableLayout

			applicationLayout.addView(tableRow, new TableLayout.LayoutParams(FP, WC));

		}

		applicationLayout.setClickable(true);

		applicationLayout.setFocusable(true);

		applicationLayout.requestFocus();

		View colView = applicationLayout.getFocusedChild();

		if(colView!=null)

		Log.e("AllAppsActivity", "AllAppsActivity->"+colView.getTag());

		

    }
