Android自定义Dialog之警告框1和警告框2 的实现(二)

这里的实现样式设计,还以圆角矩形为主。(PS: Google新出的原质化设计的确很赞,有时间一定要认真学学).

再看一下长得样子: 可以看出还是经典的警告框设计,主要包含窗口遮罩、对话框标题、描述及按钮等组成部分。详细的实现细节,看下文。

Button buttonOk = (Button) findViewById(R.id.button1);
buttonOk.setOnClickListener(new Button.OnClickListener() {
@Override
public void onClick(View arg0) {
DialogUtil.showCustomMessageOK(MainActivity.this, "Confirmation", "Just click OK to continue !");
}
});

Button buttonOkCancel = (Button) findViewById(R.id.button2);
buttonOkCancel.setOnClickListener(new Button.OnClickListener() {
@Override
public void onClick(View arg0) {
DialogUtil.showCustomMessage(MainActivity.this, "Alert", "Are you sure you want continue?");
}
});

真正的实现在DialogUtil.showCustomMessage()方法

在Style.xml中设置自定义的alert_dialog.xml

<!-- 自定义alert dialog -->
<style name="alert_dialog" parent="android:style/Theme.Dialog">

<item name="android:windowBackground">@drawable/corners_white_bg</item>
<item name="android:windowIsFloating">true</item>
<item name="android:windowContentOverlay">@null</item>

还差一个自定义的样式corners_white_bg.xml:

放在drawable文件夹下,没有的话新建。

这样警告框1,2 基本上就完成了,下篇文章中将介绍一下进度条自定义dialog的实现!
