的onClick后pssed的Andr​​oid按键设置$ P $ [英] android button setPressed after onClick

问题描述

昨天我注意到通过兼容包中集成老年API级别的碎片的可能性，但那不是真正至关重要的问题。 ：）

yesterday I noticed the possibility to integrate Fragments in older API Levels through the Compatibility package, but thats not really essential for the question. :)

我有一个OnClickListener一个按钮

I have a Button with an OnClickListener

Button button = (Button) findViewById(R.id.button);
button.setOnClickListener(new OnClickListener() {
    @Override
    public void onClick(View v) {
        doSomething();
        button.setPressed(true);
    }
});

实际的点击，因为，它显示为pssed $ P $和释放点击后，该按钮状态不是pssed $ P $，并保持这种方式。

Because of the actual clicking, it is shown as pressed and after releasing the click, the button state is not pressed and stays that way.

是否有持续释放后pssed按钮状态$ P $一个简单的方法？ 第一件事，我能想到的将是某种形式的计时器，但似乎是不合理的。

Is there a simple way that keeps the button state pressed after releasing? First thing I can think of would be some sort of timer, but that seems unreasonable.

推荐答案

您可以保留在XML文件中的按钮的状态下绘制的文件夹，然后将其用作背景的按钮。 例如：

You can keep the button states in xml file under drawable folder, then used as background for button. For example:

 android:background="@drawable/buttonstate"

buttonstate.xml

buttonstate.xml

<?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/back_focused" />
    <item android:drawable="@drawable/back" /> <!-- default -->
</selector>
