编辑文本“滞后"；安卓 [英] Edittext "lag" android

问题描述

我第一次聚焦于edittext视图时，我发现要在文本框中写任何内容之前要等待一到两秒钟.

The first time i focus an edittext view i notice a lag of one or two seconds before i can write anything in the textbox.

即使在没有任何代码的应用程序上初始化应用程序，我也注意到这种行为.

I notice this behavior even on an app without any code more than what's nessecary to initialize the application.

我在做什么错了?

推荐答案

我已为我立即修复了此问题；我在DDMS中看到，输入文本时发生了许多重绘和重新计算，并且调用了许多有关RelativeLayouts的信息.因此，我检查了自己的布局；我有一些多行EditText，它们是RelativeLayout的直接子代.因此，我将它们包装成线性布局，然后在LinearLayout而不是每个EditText上指定所需的宽度/高度.

I've INSTANTLY fixed this issue for me; I saw in the DDMS that a lot of redraw's and recalculations were occurring while entering text, and a lot of info about RelativeLayouts were being called. So, I checked my layout; i had some Multi-Line EditText's who were direct children of a RelativeLayout. So, I wrapped those up into a Linear Layout, and specified my desired width/height at the LinearLayout, not each EditText.

猜猜是什么?完全解决了！

(下面，有一些代码...请记住，这只是一个近似值.请勿尝试复制/粘贴)

(below, some code... keep in mind, this is just an approximation. Don't try and copy/paste)

之前:

<RelativeLayout>
    <EditText
        android:layout_width="wrap_content" />
    <EditText
        android:layout_width="wrap_content" />
</RelativeLayout>

之后:

<RelativeLayout>
    <LinearLayout
        android:layout_width="wrap_content" >
        <EditText
            android:layout_width="fill_parent" />
        <EditText
            android:layout_width="fill_parent" />
    </LinearLayout>
</RelativeLayout>

将我的EditText包装到LinearLayout中，然后将动态布局控件放到LinearLayout中. 这是一个了不起的即时改进.

Wrapped my EditText's into a LinearLayout, and relinquished dynamic layout controls to the LinearLayout. It was an amazing and instant improvement.
