变化背景彩色星体,然后取回原色和roid
原标题:Change background color onclick and then retrieve the original color android

在我的申请中,我扩大了基础适应者,并创建了我自己的适应者。 我有不同的背景形象取决于他们的立场。 在被点击的“COMPLISHED”时,我想改变任何行的颜色,而N在进行浮标之后又取出第一个背景颜色。 这里用我的浮标方法改变背景。

    public void onClick(View v) {

            if(pos==0)
            v.setBackgroundResource(R.drawable.stoprow);
            else if(pos==getCount()-1)
            v.setBackgroundResource(R.drawable.sbottomrow);
            else
                v.setBackgroundResource(R.drawable.smiddlerow);

            Intent details = new Intent(v.getContext(),HomeworkDetails.class);
            details.putExtra("date", data.get(pos).getDateOfAdd() );
            details.putExtra("dueDate", data.get(pos).getDuedate());
            details.putExtra("course", data.get(pos).getCourse());
            details.putExtra("note", data.get(pos).getNote());
            details.putExtra("iconLink", links.get(pos));
            v.getContext().startActivity(details);
        }
        });

现在,我如何能够在<条码>上()之后改变背景。

问题回答

简而言之,可在内部选任人使用。 宣布两件物品,并施压。 一种真实的错误。

届时,你可以向纽特纳施舍。

在以下情况下可与选任人选用:

<?xml version="1.0" encoding="utf-8"?><selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true" android:drawable="@drawable/button_on" />
<item android:state_pressed="false" android:drawable="@drawable/button_off" /></selector>
