Question

在我的视图中，我想在tablerow视图中添加imageview，它在列表视图中膨胀，因此我可以在列表视图中动态添加imageview，但我无法动态添加表行。请帮我解决这个问题。

这是类文件：

public class MainActivity extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    ListView imagegrid = (ListView) findViewById(R.id.listView1);

    imagegrid.setAdapter(new ImageAdapter(this));
}

public class ImageAdapter extends BaseAdapter {
    private LayoutInflater mInflater;
    private Activity mContext;

    public ImageAdapter(Activity mainActivity) {
        mInflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        mContext = mainActivity;
    }

    public int getCount() {
        return 10;
    }

    public Object getItem(int position) {
        return position;
    }

    public long getItemId(int position) {
        return position;
    }

    public View getView(int position, View convertView, ViewGroup parent) {

        View customRow = mInflater.inflate(R.layout.row, null);
        TableLayout tl = (TableLayout) customRow.findViewById(R.id.scroll);
        /* Create a new row to be added. */

        TableRow tr = new TableRow(mContext);
        tr.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT,
                LayoutParams.WRAP_CONTENT));

        /*
         * Create view to add view to row, here i am adding only button you
         * can andd any view you want
         */
        Button b = new Button(mContext);
        b.setText("Dynamic Button");
        b.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT,
                LayoutParams.WRAP_CONTENT));
        /* Add Button to row. */
        tr.addView(b);

        /* Add row to TableLayout. */
        tl.addView(tr, new TableLayout.LayoutParams(
                LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT));
        return customRow;
    }
}

这是我的xml文件....

<TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/scroll"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginRight="0dp"
android:orientation="vertical" >

您需要执行以下步骤

TableLayout tl = (TableLayout)findViewById(R.id.yourtbllayout);
/* Create a new row to be added. */

TableRow tr = new TableRow(this);
tr.setLayoutParams(new LayoutParams(
LayoutParams.FILL_PARENT, 
LayoutParams.WRAP_CONTENT));

/*Create view to add view to row, here i am adding only button you can andd any view you want*/
                Button b = new Button(this);
            b.setText("Dynamic Button");
            b.setLayoutParams(new LayoutParams(
                    LayoutParams.FILL_PARENT, 
                    LayoutParams.WRAP_CONTENT));
            /* Add Button to row. */
            tr.addView(b);


/* Add row to TableLayout. */
tl.addView(tr,new TableLayout.LayoutParams(
LayoutParams.FILL_PARENT, 
LayoutParams.WRAP_CONTENT));
