[英]Icons in custom dialogs android
Is there a way to set an icon on a custom dialog without using the AlertDialog methods? 有没有办法在不使用AlertDialog方法的情况下在自定义对话框上设置图标? Dialog has title, but is missing that nice divider and the ability to set an icon, but surely there must be a way of getting both without having to use AlertDialog?
Dialog有标题,但缺少漂亮的分隔符和设置图标的能力,但肯定必须有一种方法来获得两者而不必使用AlertDialog?
You can add an icon with the following code: 您可以使用以下代码添加图标:
Dialog dialog = new Dialog(context);
dialog.requestWindowFeature(Window.FEATURE_LEFT_ICON);
dialog.setContentView(R.layout.custom_dialog);
dialog.setTitle("Dialog Title");
dialog.show();
dialog.setFeatureDrawableResource(Window.FEATURE_LEFT_ICON, R.drawable.your_icon);
For a divider you can simply add an ImageView
to your dialog layout: 对于分隔符,您只需将
ImageView
添加到对话框布局中:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical">
<ImageView
android:src="@android:drawable/divider_horizontal_dim_dark"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<TextView
android:text="content"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</LinearLayout>
A nice way of adding a divider is by using a gradient shape. 添加分隔符的一种好方法是使用渐变形状。
Simply make a file gradient.xml
or so, in your res/drawable/
catalog and put something like this into it: 只需在
res/drawable/
catalog中创建一个文件gradient.xml
左右,并将类似内容放入其中:
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<gradient android:startColor="#424542"
android:centerColor="#FFFFFF"
android:endColor="#424542"
android:angle="0" />
</shape>
And then inside your LinearLayout you can put a View: 然后在你的LinearLayout中你可以放一个视图:
<View android:id="@+id/divider"
android:layout_width="fill_parent"
android:layout_height="1dip"
android:background="@drawable/gradient">
</View>
Then it paints a nice gradient divider :) 然后它描绘了一个漂亮的渐变分隔器:)
