1. 为自定义Preference 添加背景：custom_preference_background.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android"><item><shape android:shape="rectangle" ><gradient android:startColor="@color/white" android:endColor="@color/white" android:angle="90"/><corners android:radius="8dp"/></shape></item>
</selector>

2. 自定义layout： layout_custom_click_preference.xml

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"xmlns:app="http://schemas.android.com/apk/res-auto"android:layout_width="match_parent"android:layout_height="wrap_content"android:paddingVertical="20dp"android:layout_marginHorizontal="20dp"android:layout_marginVertical="8dp"android:background="@drawable/custom_preference_background"><androidx.appcompat.widget.AppCompatTextViewandroid:id="@+id/custom_preference_text"android:layout_width="wrap_content"android:layout_height="wrap_content"android:textSize="16sp"android:textColor="#111111"android:text="@string/text_help_page"android:layout_marginStart="20dp"app:layout_constraintStart_toStartOf="parent"app:layout_constraintTop_toTopOf="parent"app:layout_constraintBottom_toBottomOf="parent"/><androidx.appcompat.widget.AppCompatImageViewandroid:id="@+id/custom_preference_icon"android:layout_width="wrap_content"android:layout_height="wrap_content"android:src="@drawable/ic_preference_back"android:layout_marginEnd="20dp"app:layout_constraintEnd_toEndOf="parent"app:layout_constraintTop_toTopOf="parent"app:layout_constraintBottom_toBottomOf="parent"/>
</androidx.constraintlayout.widget.ConstraintLayout>

3. 自定义style:

    <declare-styleable name="customClickPreferenceView"><attr name="iconDrawable" format="reference|color" /></declare-styleable>

4.自定义图标

<vector xmlns:android="http://schemas.android.com/apk/res/android"android:width="16dp"android:height="16dp"android:viewportWidth="16"android:viewportHeight="16"><pathandroid:pathData="M5.869,12.862L5.869,12.862A0.667,0.667 45.145,0 1,5.869 11.919L10.319,7.47A0.667,0.667 45.145,0 1,11.262 7.47L11.262,7.47A0.667,0.667 45.145,0 1,11.262 8.413L6.812,12.862A0.667,0.667 45.145,0 1,5.869 12.862z"android:fillColor="#000"/><pathandroid:pathData="M5.682,2.729L5.682,2.729A0.667,0.667 45.145,0 1,6.625 2.729L11.075,7.178A0.667,0.667 45.145,0 1,11.075 8.121L11.075,8.121A0.667,0.667 45.145,0 1,10.132 8.121L5.682,3.672A0.667,0.667 45.145,0 1,5.682 2.729z"android:fillColor="#000000"/>
</vector>

5. 完整代码

public class CustomClickPreference extends Preference {private AppCompatTextView textView;private AppCompatImageView imageView;private int iconDrawable;public CustomClickPreference(Context context, AttributeSet attrs) {super(context, attrs);setLayoutResource(R.layout.layout_custom_click_preference);TypedArray typedArray = context.obtainStyledAttributes(attrs, R.styleable.customClickPreferenceView);if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {iconDrawable = typedArray.getResourceId(R.styleable.customClickPreferenceView_iconDrawable, R.drawable.ic_preference_back);}typedArray.recycle();}@Overridepublic void onBindViewHolder(PreferenceViewHolder holder) {super.onBindViewHolder(holder);// 自定义布局textView = (AppCompatTextView) holder.findViewById(R.id.custom_preference_text);imageView = (AppCompatImageView) holder.findViewById(R.id.custom_preference_icon);textView.setText(getTitle());imageView.setImageResource(iconDrawable);}public void setIconDrawable(int resourceId) {imageView.setImageResource(resourceId);}
}

6. 用法

    <com.tetras.sensechat.wedgit.CustomClickPreferenceapp:iconDrawable="@drawable/ic_preference_back"app:isPreferenceVisible="false"app:key="key_document_help"app:title="帮助文档" />
