推荐答案

您需要添加的 OnClickListner接口以您的活动，然后添加所有动态视图为 setOnClickListner 最后你可以捕捉点击事件里面的的onClick（视图查看）方式的所有观点。

You need to add OnClickListner Interface to your activity and then add all dynamic view to setOnClickListner and finally you can catch click event for all view inside onClick(View view) method.

试试这个

public class MainScreen extends Activity implements OnClickListener {

int i = 10; // input no of row

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);  // set here your layout xml name 

    //TableLayout tl = new TableLayout(MainScreen.this);
        TableLayout tl = (TableLayout) findViewById(R.id.table);
    for (int k = 0; k < i; k++) {

        TableRow tr = new TableRow(MainScreen.this);
        tr.layout(0, 0, 0, 0);
        TextView ids = new TextView(MainScreen.this);
        ids.setText(loc_id[k]);
        ids.setPadding(30, 15, 30, 15);
        TextView loc = new TextView(MainScreen.this);
        loc.setText(loc_name[k]);
        loc.setPadding(30, 15, 30, 15);
        tr.setPadding(0, 1, 0, 0);
        tr.addView(ids);
        tr.addView(loc);
        tr.setId(k); // here you can set unique id to TableRow for
                        // identification
        tr.setOnClickListener(MainScreen.this); // set TableRow onClickListner
        tl.addView(tr, new TableLayout.LayoutParams(
                LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));

    }

    //setContentView(tl);
}

@Override
public void onClick(View v) {
    // TODO Auto-generated method stub

    int clicked_id = v.getId(); // here you get id for clicked TableRow

    // now you can get value like this

    String ids = loc_id[clicked_id];
    String loc = loc_name[clicked_id];

}
}
