我试图在AlertDialog
上添加圆角,但是我不了解形状文件的逻辑(不起作用)。我在RelativeLayout
的{{1}}中将其用作背景,但似乎它被忽略了。这是形状文件:
AlertDialog
这是警报对话框xml:
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<solid android:color="@android:color/transparent"/>
<corners android:radius="10dp" />
<padding android:left="10dp" android:right="10dp"/>
</shape>
And this is the result 我想念什么?

只需使用Android库的官方材料组件中包含的官方Material AlertDialog。
new MaterialAlertDialogBuilder(context)
.setTitle("Title")
.setMessage("Message")
.setPositiveButton("Ok", null)
.show();
并使用主题
<item name="materialAlertDialogTheme">@style/ThemeOverlay.MaterialComponents.MaterialAlertDialog</item>
它遵循准则:
您可以使用 shapeAppearanceOverlay
属性customize the shape来使用组件。
类似的东西:
<!-- Alert Dialog -->
<style name="MyThemeOverlayAlertDialog" parent="@style/ThemeOverlay.MaterialComponents.MaterialAlertDialog">
<item name="shapeAppearanceOverlay">@style/ShapeAppearanceOverlay.MyApp.Dialog.Rounded</item>
</style>
<style name="ShapeAppearanceOverlay.MyApp.Dialog.Rounded" parent="">
<item name="cornerFamily">rounded</item>
<item name="cornerSize">8dp</item>
</style>

使用Dialog
类而不是AlertDialogBuilder
。
代码段
使用Dialog类而不是showDialog()
来定义此方法AlertBuilder
public void showDialog() {
final Dialog dialog = new Dialog(this);
dialog.setContentView(R.layout.your_xml);
Button dialog_neutral_btn = dialog.findViewById(R.id.dialog_neutral_btn);
Button dialog_positive_btn = dialog.findViewById(R.id.dialog_positive_btn);
Button dialog_negative_btn=dialog.findViewById(R.id.dialog_negative_btn);
TextView dialog_titile = dialog.findViewById(R.id.dialog_titile);
TextView dialog_tv = dialog.findViewById(R.id.dialog_tv);
// do you stuff here , define click listeners
dialog.show();
}
用法
yourButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
showDialog();
}
});
注意:-
android.support.v7.app.AlertDialog
代替
android.app.AlertDialog
如果您想使用AlertDialogBuilder

我检查了您的形状,并在手机上看起来不错,我的形状与+渐变效果相同:
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<gradient
android:angle="-90"
android:centerColor="#F2F2F2"
android:endColor="#ADA996"
android:startColor="#DBDBDB" />
<stroke
android:width="2dp"
android:color="#000000" />
<corners android:radius="8dp" />
<padding
android:bottom="4dp"
android:left="4dp"
android:right="4dp"
android:top="4dp" />
</shape>
尝试使用上面的形状,如果仍然无法使用,请尝试在单个按钮上使用形状-如果您看到形状正确运行,您将知道问题出在布局文件中。
也许您需要做的所有Invalidate Caches/Restart
,可能没有错,但您的应用使用的是来自缓存的旧形状

您的shape_dialog.xml应该类似于
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<solid
android:color="@color/white"/>
<corners
android:radius="30dp" />
<padding
android:left="10dp"
android:top="10dp"
android:right="10dp"
android:bottom="10dp" />
</shape>
您需要设置对话框透明背景的背景。
dialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));

您可以通过执行以下步骤来实现。
您必须为Textview和主布局创建两个形状可绘制的xml
1. border_no_white_bg.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<solid android:color="@color/white" />
<stroke
android:width="1dp"
android:color="@color/white" />
<corners android:radius="6dp" />
</shape>
2. shape_button_orange_bg_with_radius.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<stroke
android:width="1dp"
android:color="@color/black" />
<corners android:radius="15dp" />
</shape>
3. Now in main_popup.xml, replace by below code
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:layout_margin="15dp"
android:background="@drawable/border_no_white_bg"
android:orientation="vertical">
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:layout_margin="10dp"
android:background="#CCCCCC"
android:baselineAligned="false"
android:gravity="center"
android:padding="10dp"
android:text="Scegli un'operazione"
android:textColor="#000"
android:textSize="18sp" />
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:layout_margin="10dp"
android:baselineAligned="false"
android:gravity="center"
android:padding="10dp"
android:text="Vuoi aprire o eliminare il test?"
android:textColor="#000"
android:textSize="18sp" />
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginBottom="15dp"
android:orientation="horizontal">
<Button
android:layout_width="wrap_content"
android:layout_height="40dp"
android:layout_marginLeft="15dp"
android:layout_marginRight="15dp"
android:background="@drawable/shape_button_orange_bg_with_radius"
android:text="Indietro"
android:textColor="#000"
android:textSize="14sp" />
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:orientation="horizontal">
<Button
android:layout_width="wrap_content"
android:layout_height="40dp"
android:layout_marginLeft="5dp"
android:layout_marginRight="5dp"
android:background="@drawable/shape_button_orange_bg_with_radius"
android:text="Apri"
android:textColor="#000"
android:textSize="14sp" />
<Button
android:layout_width="wrap_content"
android:layout_height="40dp"
android:layout_marginLeft="5dp"
android:layout_marginRight="15dp"
android:background="@drawable/shape_button_orange_bg_with_radius"
android:text="Elimina"
android:textColor="#000"
android:textSize="14sp" />
</LinearLayout>
</RelativeLayout>
</LinearLayout>
</RelativeLayout>
4. popup_window_animation
Inside res->values->style.xml, add this code
<style name="popup_window_animation">
<item name="android:windowEnterAnimation">@anim/fade_in</item>
<item name="android:windowExitAnimation">@anim/fade_out</item>
</style>
现在创建一种方法来调用此布局
public void showPopup(View anchorView) {
final View popupView = getLayoutInflater().inflate(R.layout.main_popup, null);
RelativeLayout layout_close;
// Declare your views here
final PopupWindow popupWindow = new PopupWindow(popupView, ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);
popupWindow.setAnimationStyle(R.style.popup_window_animation);
layout_feedback_close = (RelativeLayout) popupView.findViewById(R.id.layout_feedback_close);
// Here find view by ids
layout_feedback_close.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
}
});
popupWindow.setFocusable(true);
popupWindow.setBackgroundDrawable(new ColorDrawable());
int location[] = new int[2];
anchorView.getLocationOnScreen(location);
popupWindow.showAtLocation(anchorView, Gravity.CENTER, location[0], location[1] + anchorView.getHeight());
}
