Android之仿IOS对话框

开发过程中经常用到对话框，单选的，多选的 ，列表式的各式各样。

老规矩先上图。我是直接拿了项目的切图，背景，文字颜色或者图片可以自行替换。

核心代码

// 自定义对话框
private void fifthResult() {
final Dialog dialog = new Dialog(this, R.style.AlertDialogStyle);
View view = View.inflate(this, R.layout.view_alertdialog, null);
TextView mCancel = (TextView) view.findViewById(R.id.cancel_tv);
TextView mConfirm = (TextView) view.findViewById(R.id.confirm_tv);
mCancel.setText("取消");
mConfirm.setText("确定");
dialog.setContentView(view);
// 使得点击对话框外部不消失对话框
dialog.setCanceledOnTouchOutside(true);
// 设置对话框的大小
view.setMinimumHeight((int) (ScreenSizeUtils.getInstance(this).getScreenHeight() * 0.23f));
Window dialogWindow = dialog.getWindow();
WindowManager.LayoutParams lp = dialogWindow.getAttributes();
lp.width = (int) (ScreenSizeUtils.getInstance(this).getScreenWidth() * 0.75f);
lp.height = WindowManager.LayoutParams.WRAP_CONTENT;
lp.gravity = Gravity.CENTER;
dialogWindow.setAttributes(lp);
mCancel.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
dialog.dismiss();
}
});
mConfirm.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
dialog.dismiss();
}
});
dialog.show();

}

计算手机屏幕的宽高

public static class ScreenSizeUtils {
private static ScreenSizeUtils instance = null;
private int screenWidth, screenHeight;
public static ScreenSizeUtils getInstance(Context mContext) {
if (instance == null) {
synchronized (ScreenSizeUtils.class) {
if (instance == null)
instance = new ScreenSizeUtils(mContext);
}
}
return instance;
}
private ScreenSizeUtils(Context mContext) {
WindowManager manager=(WindowManager) mContext.getSystemService(Context.WINDOW_SERVICE);
DisplayMetrics dm = new DisplayMetrics();
manager.getDefaultDisplay().getMetrics(dm);
screenWidth = dm.widthPixels;// 获取屏幕分辨率宽度
screenHeight = dm.heightPixels;// 获取屏幕分辨率高度
}
// 获取屏幕宽度
public int getScreenWidth() {
return screenWidth;
}
// 获取屏幕高度
public int getScreenHeight() {
return screenHeight;
}
}

style

    <style name="AlertDialogStyle" parent="@android:style/Theme.Dialog">
        <item name="android:windowBackground">@android:color/transparent</item>
        <item name="android:windowContentOverlay">@null</item>
        <item name="android:windowIsFloating">true</item>
        <item name="android:windowFrame">@null</item>
        <item name="android:backgroundDimEnabled">true</item>
        <item name="android:windowNoTitle">true</item>
        <item name="android:windowIsTranslucent">true</item>

    </style>
