我有一个HDF5数据库,其中包含1亿多行文本,每个文本都存储一组简单的三列值:
@Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
Logger.debug(TAG, "onConfigChanged");
updateLayout(newConfig.orientation);
}
/**
* Update the current layout params according to current device orientation.
*/
private void updateLayout(int orientation) {
LinearLayout.LayoutParams favParams = (LinearLayout.LayoutParams) mFavoriteLayout.getLayoutParams();
LinearLayout.LayoutParams historyParams = (LinearLayout.LayoutParams) mHistoryLayout.getLayoutParams();
LinearLayout.LayoutParams colParams = (LinearLayout.LayoutParams) mColumnLayout.getLayoutParams();
if (orientation == Configuration.ORIENTATION_PORTRAIT) {
mColumnLayout.setOrientation(LinearLayout.VERTICAL);
historyParams.width = favParams.width = ViewGroup.LayoutParams.MATCH_PARENT;
historyParams.height = favParams.height = 0;
colParams.weight = 1.0f;
} else if (orientation == Configuration.ORIENTATION_LANDSCAPE) {
mColumnLayout.setOrientation(LinearLayout.HORIZONTAL);
historyParams.height = favParams.height = ViewGroup.LayoutParams.MATCH_PARENT;
historyParams.width = favParams.width = 0;
colParams.weight = 2.0f;
}
// Set back updated params and redraw
mFavoriteLayout.setLayoutParams(favParams);
mHistoryLayout.setLayoutParams(historyParams);
mColumnLayout.setLayoutParams(colParams);
mColumnLayout.invalidate();
}
我想在“WORD”栏目中搜索 的所有点击(例如,'cats','sat','mats')。
在其他一些数据库(例如PostgresQL)中,我可以使用简单的正则表达式搜索“?at?”来完成此操作。如果我可以使用正则表达式搜索HDF5索引,那就没问题了。但是,我不认为这是可能的。有关如何快速进行这种“通配符”(正则表达式)搜索的任何建议吗?
答案 0 :(得分:0)
尝试以下正则表达式
[^\s]+[\s]+([a-zA-Z]*at[a-zA-Z]*)[\s]+[^\s]+
上述正则表达式中的第1组将为您提供所需的结果。
"WORD" column to find all hits for at (i.e., 'cats', 'sat', 'mats').
