Question

我在ExpandableListView的每个子项中都有一个EditText，但是有一个问题：当我单击EditText时，有时光标正常闪烁，但有时光标不会出现，或者光标出现但不闪烁。

我尝试了很多方法，但没有人工作。

以下是我尝试但不工作的方式：

为Java中的子项的每个EditText设置

View.OnFocusChangeListener onFocus = new View.OnFocusChangeListener() {
    @Override
    public void onFocusChange(View v, boolean hasFocus) {
        v.dispatchWindowFocusChanged(hasFocus);
    }
};

为ExpandableListView设置

android:descendantFocusability="afterDescendants"
android:focusable="false"

为xml中的子项设置

    android:textCursorDrawable="@null"
    android:cursorVisible="true"

我不知道这个问题，请帮助，非常感谢~~~

当我发现Handler内部无效计时器因某种原因停止时发生了这种情况。我不知道为什么。

我所能做的就是创建自己的EditText以使我的课程内的视图无效@Override protected void onFocusChanged(boolean focused, int direction, Rect previouslyFocusedRect) { super.onFocusChanged(focused, direction, previouslyFocusedRect); if(focused) { handler.postDelayed(this, 200); } else { handler.removeCallbacks(this); } } @Override public void run() { invalidate(); new Thread(new Runnable() { @Override public void run() { try { Thread.sleep(250); if(hasFocus()) { handler.post(MyEditText.this); } } catch (InterruptedException e) { e.printStackTrace(); } } }).start(); }。

@Bean
public IntegrationFlow processProduct() {
    return IntegrationFlows.from(mongoMessageSource(mongoDbFactory),
            c -> c.poller(Pollers.cron(cron)))
            .enrichHeaders(m -> m.header("errorChannel", deleteFileErrorChannel))
            .split()
            .channel(deleteFileChannel())
            .get();
}


@Bean
public MessageSource<Object> mongoMessageSource(MongoDbFactory mongo) {
    long innerBoundary = Instant.now().toEpochMilli();
    long outerBoundary = Instant.now().plus(XXXXX).toEpochMilli();

    log.info("Delete file with modification date between {} and {}", outerBoundary, innerBoundary);
    String expression = new StringBuilder()
            .append("{value: { $gte: \"")
            .append(outerBoundary)
            .append("\", $lt : \"")
            .append(innerBoundary)
            .append("\"}}")
            .toString();
    log.info("Running mongo query {}", expression);

    MongoDbMessageSource messageSource = new MongoDbMessageSource(mongo, new LiteralExpression(expression));
    messageSource.setExpectSingleResult(false);
    messageSource.setEntityClass(MetaDataStore.class);
    messageSource.setCollectionNameExpression(new LiteralExpression("treated_file"));
    return messageSource;
}

@Bean
public IntegrationFlow deleteFileFlow() {
    return IntegrationFlows.from(deleteFileChannel())
            //Add file name and directory to header
            .enrichHeaders(m -> m
                    .header("file_remoteDirectory", sourceFtpDirectory)
                    .headerExpression("file_remoteFile", "payload.id")
            )
            //Delete files
            .handle(Sftp
                    .outboundGateway(
                            sourceFtpSessionFactory,
                            AbstractRemoteFileOutboundGateway.Command.RM,
                            "headers['file_remoteDirectory'] + '/' + headers['file_remoteFile']")
            )
            .get();
}

我不认为这是一个很好的解决方案。如果你知道的更好，请写下来。
