自定义警报对话框背景颜色
custom alert dialog background color
我需要一个自定义警报对话框来显示进度。当我 运行 时,警告对话框的背景颜色不会变为透明...
下面我将我的代码放在 xml 布局和警报对话框代码中
xml布局:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:orientation="vertical"
android:background="@android:color/transparent"
android:layout_width="match_parent"
android:gravity="center"
android:layout_height="match_parent">
<androidx.cardview.widget.CardView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
app:cardElevation="10dp"
app:cardCornerRadius="100dp">
<ProgressBar
android:id="@+id/progressBar"
style="@style/Widget.AppCompat.ProgressBar"
android:layout_width="30dp"
android:layout_margin="5dp"
android:layout_height="30dp" />
</androidx.cardview.widget.CardView>
这是我的片段代码:
View progress = getLayoutInflater().inflate(R.layout.progress_alert, null);
AlertDialog.Builder builder = new AlertDialog.Builder(getContext());
builder.setCancelable(false);
builder.setView(progress);
alertDialog = builder.create();
alertDialog.show();
您可以将警告对话框的背景颜色更改为透明:
alertDialog.getWindow().getDecorView().setBackgroundResource(android.R.color.transparent);
您可以像这样为进度条创建 xml 文件:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="@+id/relativeLayoutProgressBar"
android:visibility="gone"
android:elevation="8dp"
>
<ProgressBar
android:layout_width="wrap_content"
android:layout_height="50dp"
style="?android:attr/progressBarStyle"
android:indeterminate="true"
android:layout_centerInParent="true"
android:theme="@style/RedAccent"
android:elevation="5dp"
/>
<View
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#CCFFFFFF"
android:elevation="4dp"
/>
</RelativeLayout>
并在 xml 文件中包含此布局行,您需要这样的进度条:
<include layout="progressbar" />
并像这样访问:
RelativeLayout layout = findViewById(R.id.relativeLayoutProgressBar);
layout.setVisibility(View.GONE);
试试这个,
final AlertDialog alertDialog = dialogBuilder.create();
alertDialog.getWindow().setBackgroundDrawable(new
ColorDrawable(Color.TRANSPARENT));
alertDialog.show();
尝试在 styles.xml
中设置这样的对话框主题
<style name="dialogTheme" parent="android:Theme.Holo.Dialog">
<item name="android:windowMinWidthMajor">90%</item>
<item name="android:windowMinWidthMinor">90%</item>
</style>
java代码
Dialog dialog = new Dialog(activity, R.style.dialogTheme);
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog.setContentView(R.layout.your_dialog_layout);
activity.getWindow().setLayout(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.MATCH_PARENT);
dialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
