在空白屏幕的Android结果片段的交易

本文介绍了在空白屏幕的Android结果片段的交易的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

如果有帮助，我要的是类似的是，在此

If it helps, what I want is similar to what is done in this google tutorial

但是有一个片段到过渡之前创建的。如果我这样做，转变工作正常;但我不能使用这种方法。

But there a fragment is created prior to the transition. If I do that the transition works fine; but I can't use this approach

=====

针对给API 7+我只是想有一个片段，在整个屏幕上可见，用一个按钮（一个拉制按钮，用onTouch事件），那么替代品的第二片段，反之亦然。

Aiming to API 7+ I am just trying to have one Fragment visible in the whole screen and using a button (a drawn button, with an onTouch event) then alternate to a second fragment and viceversa.

不过，我要么得到了一个空白页面，当我更换了与第二第一个片段，或者如果我使用fragmentTransaction.show和fragmentTransaction.hide;我可以切换两次之前，我空白屏幕。我不想对backstack。

But I either get a blank screen when I replace the first fragment with the second, or if I use fragmentTransaction.show and fragmentTransaction.hide; I can switch two times before I get blank screen. I dont want to have on backstack.

我在MainActivity的onCreate创建片段：

I am creating the fragments in MainActivity's onCreate:

DiceTable diceTable = new DiceTable();
Logger logger = new Logger();
fragmentTransaction.add(diceTable, DICETABLE_TAG);
fragmentTransaction.add(logger, LOGGER_TAG);
fragmentTransaction.add(R.id.fragment_container, logger);
fragmentTransaction.add(R.id.fragment_container, diceTable);

然后在一种方法（从片段调用）我做的开关：

Then on one method (called from the fragments) I do the switch:

    Logger logger = (Logger)fragmentManager.findFragmentByTag(LOGGER_TAG);
    DiceTable diceTable = (DiceTable)fragmentManager.findFragmentByTag(DICETABLE_TAG);

    if (diceTable.isVisible()) {
        fragmentTransaction.replace(R.id.fragment_container, logger);

        fragmentTransaction.commit();
        fragmentTransaction.hide(diceTable);
        fragmentTransaction.show(logger);
    }
    else if (logger.isVisible()) {
        fragmentTransaction.replace(R.id.fragment_container, diceTable);

        fragmentTransaction.commit();
        fragmentTransaction.hide(logger);
        fragmentTransaction.show(diceTable);
    }

这是不是我应该怎么做呢？

This is not how I should do this?

替换片段时黑屏

推荐答案

尝试以这种方式来初始化片段：

Try to initialize fragments in that way:

private void initFragments() {
    mDiceTable = new DiceTable();
    mLogger = new Logger();
    isDiceTableVisible = true;

    FragmentManager fm = getSupportFragmentManager();
    FragmentTransaction ft = fm.beginTransaction();
    ft.add(R.id.fragment_container, mDiceTable);
    ft.add(R.id.fragment_container, mLogger);
    ft.hide(mLogger);
    ft.commit();
}

然后以这种方式它们之间翻转：

And then flip between them in that way:

 private void flipFragments() {
        FragmentManager fm = getSupportFragmentManager();
        FragmentTransaction ft = fm.beginTransaction();
        if (isDiceTableVisible) {
            ft.hide(mDiceTable);
            ft.show(mLogger);
        } else {
            ft.hide(mLogger);
            ft.show(mDiceTable);
        }
        ft.commit();
        isDiceTableVisible = !isDiceTableVisible;
    }
