我有一个按钮，当我按下按钮时希望它保持按下状态(Froyo上为绿色).

I have a button, and I want that when I press it, it stays as pressed (with the green color on Froyo).

有帮助吗?

mycodes_Button = (Button) findViewById(R.id.mycodes);
...
if (saved_Button.isPressed())
{
    saved_Button.setFocusable(true);
}

像这样吗?

推荐答案

使用以下代码.这很有用.

Use the following code. It's useful.

mycodes_Button.setOnTouchListener(new OnTouchListener() {
    @Override
    public boolean onTouch(View v, MotionEvent event) {
        mycodes_Button.setPressed(true);
        return true;
    }
});
