Question

我正在动态地制作一个图象布特顿的表格,我想为图像纽芬兰语打真。当被用户点击时。自2006年以来我已生动地建立了纽子,我是如何在ClickListener上调的?

        {
            ImageButton b = new ImageButton(this);
            b.setLayoutParams(new TableRow.LayoutParams(
                                LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT));
            b.setBackgroundResource(R.drawable.happy);
            b.setOnClickListener(new OnClickListener() {
                            public void onClick(View v) {
                                onClickListenerForTag("tagStr");
                            }
            }
        }

    private void onClickListenerForTag(final String tagStr) {
            assert (tagStr != null);
                    mTagStr = tagStr;
                    //need to call setPressed(true) here ?

        }

The View being adopted in to thehandler is the button instance. Cast the Button and打上该方法。

public void onClick(View v) {
     onClickListenerForTag("tagStr", v);
    }

private void onClickListenerForTag(final String tagStr, View v) {
            assert (tagStr != null);
            mTagStr = tagStr;

            ImageButton button = (ImageButton)v;
            button.setPressed(true);
    }
