我想在警告对话框中添加阴影效果。 i want this type of shadow effect in my dialog box 这里我首先发布3个文件是style.xml,第二个是theme.java,第三个文件是demo_bg.xml file.i已经尝试过这样
Style.xml
<style name="AppCompatAlertDialogStyle" parent="Theme.AppCompat.Light.Dialog.Alert">
<item name="colorAccent">@color/bg_color</item>
<item name="android:textColorPrimary">@color/colorBlack</item>
<item name="android:background">@drawable/demo_bg</item>
</style>
theme.java
final AlertDialog.Builder builder =
new AlertDialog.Builder(this, R.style.AppCompatAlertDialogStyle);
builder.setMessage(R.string.wsdialogdata);
builder.setPositiveButton("START", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialogInterface, int i) {
Intent ii = new Intent(WelcomeFromActivity.this, Question1Activity.class);
startActivity(ii);
}
});
builder.show();
demo_bg.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<layer-list>
<!-- SHADOW LAYER -->
<item android:left="2dp" android:top="2dp">
<shape>
<solid android:color="#66000000" />
<corners android:radius="35dip" />
</shape>
</item>
<!-- CONTENT LAYER -->
<item android:bottom="4dp" android:right="4dp">
<shape>
<solid android:color="@color/btn_fb" />
<corners android:radius="40dip" />
</shape>
</item>
</layer-list>
</item>
</selector>

我在
下面创建了自定义阴影文件(shadow.xml)<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape android:shape="rectangle"> <!-- this shape is used as shadow -->
<padding android:bottom="5dp"
android:left="5dp"
android:right="5dp"
android:top="5dp"/>
<solid android:color="#44000000"/>
<corners android:radius="5dp"/>
</shape>
</item>
<item>
<shape android:shape="rectangle"> <!-- this is for dialog frame -->
<corners android:radius="5dp"/>
<stroke android:color="#ff272727" android:width="2dp" />
<gradient android:angle="90"
android:startColor="#ffa7a7a7"
android:centerColor="#ff6a6a6a"
android:endColor="#ffa7a7a7"
android:type="linear"/>
</shape>
</item>
</layer-list>
在下一步中,您应该按照以下内容更改对话框主题:
<style name="dialog_theme">
<item name="android:windowBackground">@drawable/shadow</item>
</style>
现在你完成了,只需创建一个Dialog类的新实例并将此主题应用于它(在Dialog构造函数中):
Dialog dialog = new Dialog(this, R.style.dialog_theme);
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog.setContentView(R.layout.mdialog);
dialog.show();

我知道我来不及。然而,它可能会帮助那些需要帮助并希望以简单方式实现这一目标的人。 只需将其添加到xml中的父布局。
android:background="@android:drawable/dialog_holo_light_frame"
例如:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="@android:drawable/dialog_holo_light_frame"
android:orientation="vertical">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:drawablePadding="10dp"
android:drawableStart="@drawable/filter"
android:gravity="center"
android:text="Filter"
android:textColor="@color/grey"
android:textSize="18sp" />
</LinearLayout>
所以这里LinearLayout是你的父母。所以补充一下,
android:background="@android:drawable/dialog_holo_light_frame"
会这样做。
希望它有所帮助。感谢。

创建background_shadow.xml
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape>
<padding android:bottom="1dp" />
<solid android:color="#50CCCCCC" />
</shape>
</item>
<item>
<shape>
<padding android:bottom="1dp" />
<solid android:color="#10CCCCCC" />
</shape>
</item>
<item>
<shape>
<padding android:bottom="1dp" />
<solid android:color="#20CCCCCC" />
</shape>
</item>
<item>
<shape>
<padding android:bottom="1dp" />
<solid android:color="#30CCCCCC" />
</shape>
</item>
<item>
<shape>
<padding android:bottom="1dp" />
<solid android:color="#50CCCCCC" />
</shape>
</item>
<item>
<shape>
<padding android:right="1dp" />
<solid android:color="#50CCCCCC" />
</shape>
</item>
<item>
<shape>
<padding android:right="1dp" />
<solid android:color="#10CCCCCC" />

<padding android:right="1dp" />
<solid android:color="#20CCCCCC" />

<item>

<padding android:right="1dp" />
<solid android:color="#30CCCCCC" />
</shape>
</item>
<item>
<shape>
<padding android:right="1dp" />
<solid android:color="#50CCCCCC" />
</shape>
</item>
<item>
<shape>
<solid android:color="@color/white" />
</shape>
</item>
</layer-list>
风格
<style name="AppCompatAlertDialogStyle" parent="android:Theme.Dialog">
<item name="android:windowBackground">@drawable/background_shadow</item>
<item name="android:backgroundDimEnabled">false</item>
</style>
显示对话框
Dialog dialog = new Dialog(mContext, R.style.AppCompatAlertDialogStyle);
builderSingle.setTitle(getString(R.string.select_quantity));
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog.setContentView(R.layout.layout);
dialog.show();
希望这能解决您的问题
