我就是这么做的：

public class CustomPrintStream extends PrintStream {

    private String regexFilter;
private Pattern pattern;

public IonPrintStream(@NonNull File file) throws FileNotFoundException {
    super(file);
}

public String getRegexFilter() {
    return regexFilter;
}

public void setRegexFilter(String regexFilter) {
    this.regexFilter = regexFilter;
    if (regexFilter != null && !regexFilter.isEmpty()) {
        pattern = Pattern.compile(regexFilter);
    } else {
        pattern = null;
    }
}

@Override
public void println(String x) {

    if (x != null && pattern != null && !pattern.matcher(x).find()) {
        return;
    }

    System.out.println(x);
}
}

在Robolectric上的用法（你可以在你的@Before方法上做）：

File file = new File("log.txt");
        if (!file.exists() && !file.createNewFile()) {
            throw new RuntimeException("Log file could not be created");
        }

        CustomPrintStream printStream = new CustomPrintStream(file);
        printStream.setRegexFilter("[your regex here]");
        ShadowLog.stream = printStream;

型
在你的例子中，因为你不想显示一些日志，你可以像这样过滤：

//I don't want to log CursorWindowStats and SQLiteCursor tags:
        printStream.setRegexFilter("^((?!CursorWindowStats|SQLiteCursor).)*$");

在Kotlin中：

class FilterLogStream(stream: OutputStream, private val pattern: Pattern) : PrintStream(stream) {
    override fun println(x: String) {
        if (!pattern.matcher(x).find()) return
        super.println(x)
    }
}

fun PrintStream.filter(regex: String): PrintStream = FilterLogStream(this, Pattern.compile(regex))

字符串
使用方法：

ShadowLog.stream = System.out.filter("^(?!W/ShadowLegacyPath).*$")
