android中的透明对话框

时间：2015-04-01 13:41:50

标签： android xml alertdialog android-alertdialog

我正在使用一些复选框，它会显示在一个对话框上（动态地）。接下来我需要让对话框变得透明。我尝试了很多方法，但是失败了（浪费了整整一天）。可以请任何人给我一个解决方案

注意：目前我在对话框中显示白色（不透明） 以下是代码..... Transparent_alert.java 

public class Transparent_alert extends Activity{
    String tag="Transparent_alert class";
    static final String KEY_USERID = "userid";
    String errormsg = "", user_id;

    public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

如果你想使你的alertdialog透明，我不知道它是否可能，但是如下面显示的那样自定义警报对象更适合你，你只需要创建一个xml文件，设计与您当前的警报框完全相似，可以使其透明。

    dialog = new Dialog(context);
        dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
        dialog.setContentView(R.layout.dialog_profile_report);
        dialog.setCanceledOnTouchOutside(false);
        dialog.getWindow().setBackgroundDrawable(
                new ColorDrawable(android.graphics.Color.TRANSPARENT));

        dialog.show();
Button mainListView = (Button) dialog.findViewById(R.id.listview); // you can declare elements like this and can make onclick methods for these elements

尝试让对话透明，就像这样

intrestedin.xml 

 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:background="@android:color/transparent"

请将下面的代码放在风​​格

中 
 <style name="CustomAlert" parent="android:Theme.Dialog">
        <item name="android:windowBackground">@android:color/transparent</item>
        <item name="android:windowIsFloating">true</item>
        <item name="android:windowContentOverlay">@null</item>
        <item name="android:windowAnimationStyle">@android:style/Animation.Dialog</item>
        <item name="android:windowSoftInputMode">stateUnspecified|adjustPan</item>
        <item name="android:backgroundDimEnabled">false</item>
        <item name="android:background">@android:color/transparent</item>
    </style>

<强> 代码： 

Dialog mDialog = new Dialog(baseApplication.getCurrentActivity(),
                        R.style.CustomAlert);
                mDialog.setCancelable(true);
                mDialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
                mDialog.setContentView(R.layout.inflate_toast);

//you can set height width of dialog as well as position
WindowManager.LayoutParams lp = new WindowManager.LayoutParams();
                Window window = mDialog.getWindow();

            lp.copyFrom(window.getAttributes());
            lp.width = WindowManager.LayoutParams.MATCH_PARENT;
            lp.height = WindowManager.LayoutParams.WRAP_CONTENT;
            lp.gravity = Gravity.TOP;
            window.setAttributes(lp);

mDialog.show();

在您的活动中xml：

将背景设置为listview，listview的分隔符和listview的夸大布局的透明色。

<击> 取代

<击> 
alertDialog = mDialog.create();
alertDialog.show();

与

alertDialog = mDialog.create();
alertDialog.getWindow().setBackgroundDrawable(new ColorDrawable(android.graphics.Color.TRANSPARENT));
alertDialog.show();

<击>

<强>问题： 您的适配器正在膨胀行布局以在ListView中显示。正如您所看到的，它将在使用LayoutInflater进行充气时使用Parent容器进行引用。 它在创造一切透明的同时创造了问题。

选项1：   您应该考虑使用Dialog代替AlertDialog，并使用setContentView

设置所需的布局

选项2： 你会因为旧api而有一些缺点，但它会在新的api中起作用

替换

mDialog = new AlertDialog.Builder(c);

与

mDialog = (Integer.parseInt(android.os.Build.VERSION.SDK) < 11)? new AlertDialog.Builder(c) :new AlertDialog.Builder(c, android.R.style.Theme_Translucent);
