横屏Android的输入法避免全屏处理

Android输入法PinyinIME 或 Softkeyboard，在ORIENTATION_LANDSCAPE的机器上就会进入全屏模式，也就是文本框变大，除了文本框和什么都不显示了（其实可能也没有太多空间显示，不过如果是个大屏幕就难看的很了），要想解除全屏模式，需要参考如下的办法。其实修改很简单，代码路径：platform/frameworks/base/core/java/android/inputmethodservice/InputMethodService.java
749 /**750 * Re-evaluate whether the input method should be running in fullscreen751 * mode, and update its UI if this has changed since the last time it752 * was evaluated. This will call {@link #onEvaluateFullscreenMode（）} to753 * determine whether it should currently run in fullscreen mode. You754 * can use {@link #isFullscreenMode（）} to determine if the input method755 * is currently running in fullscreen mode.756 */757 public void updateFullscreenMode（） {-- 758 boolean isFullscreen = mShowInputRequested && onEvaluateFullscreenMode（）;++ 758 boolean isFullscreen = false;759 boolean changed = mLastShowInputRequested ！= mShowInputRequested;760 if （mIsFullscreen ！= isFullscreen || ！mFullscreenApplied） {761 changed = true;762 mIsFullscreen = isFullscreen;763 InputConnection ic = getCurrentInputConnection（）;764 if （ic ！= null） ic.reportFullscreenMode（isFullscreen）;765 mFullscreenApplied = true;
834 /**835 * Override this to control when the input method should run in836 * fullscreen mode. The default implementation runs in fullsceen only837 * when the screen is in landscape mode. If you change what838 * this returns, you will need to call {@link #updateFullscreenMode（）}839 * yourself whenever the returned value may have changed to have it840 * re-evaluated and applied.841 */842 public boolean onEvaluateFullscreenMode（） {843 Configuration config = getResources（）.getConfiguration（）;844 if （config.orientation ！= Configuration.ORIENTATION_LANDSCAPE） {845 return false;846 }847 if （mInputEditorInfo ！= null848 && （mInputEditorInfo.imeOptions & EditorInfo.IME_FLAG_NO_FULLSCREEN）！= 0） {849 return false;850 }851 return true;852 }
ORIENTATION_LANDSCAPE模式就是所谓的横屏模式，参见Layout。只要LANDSCAPE就全屏，那必须是横屏又不能全屏的直接设置为false即可。
