阅读更多关于 Possible to open “Speak Now” dialog programmatically?

Is it possible to open the "Speak Now" dialog programmatically? Currently, if the user taps my 'Search' button, a dialog opens and I have the soft keyboard open automatically so the user doesn't need to tap the textedit field.

阅读更多关于 Android Development: How To Get All EditText Children of a ViewGroup?

Basically, I have a LinearLayout that holds a random amount of horizontal LinearLayouts, and in each of the horizontal LinearLayouts there's a TextView and an EditText. I want to be able to get the value of each EditText children of the master LinearLayout. Sorry if it's confusing, I'm no good at explaining things!

TOPIC Solved: Answer below. Some users have been reporting border alignment issues on some android components such as the alert popup or the editTexts. This is happening on the Samsung Galaxy Apollo (200x400) and the HTC Pro Touch (480x640) devices. I cannot replicate that because i don't own those devices and in the Samsung Galaxy S and emulator everything looks just right. I think that the problem is the dpi or resolution of the device (because the edittext background is a single .9.png so image should look ok); however I am not sure if the supports-screens tag is the solution. Also,

问题 I'm looking to create a custom menu for text selection.

The behaviour I need is not the standard cut/copy/paste, the actions I have implemented are for
