Android EditText Memory Leak

由 本小妞迷上赌 提交于 2019-11-30 07:24:34

When I tap on EditText it shows something like zoom frame and then shows unusual (not standard Android alike) context menu which reads: "select text", "select all". It doesn't show my menus. Here are screenshots: Before tap During tap After tap (just ordinary select text, select all, paste) but no my menu like in emulator - look here Here's source code
