问题 The text view encircled has too much space above and below its text. It is inside the text view (not above and below of it). I neither used margins nor paddings but it is remained there. The xml code is there. <TableRow android:id="@+id/tbRow" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_below="@+id/viewLineSeparator" android:layout_gravity="top" android:layout_marginBottom="2dp" android:layout_marginTop="1dp" android:gravity="top" android:weightSum=

Triangular Bullet in Android TextView for Pre-Lollipop devices

由 牧云@^-^@ 提交于 2019-12-08 13:25:32
I Tried character encoding "& #8227;"---> and java strings "\u2023" and also tried pasting directly the Triangular Bullet "‣". I tried both 1) Directly specifying in android:text attribute and 2) Extracting from resource. All the methods specified above working fine with the Lollipop but none of them working in 4.2.2 and previous android versions. Instead of the Bullet it is showing some rectangular box. any ideas how to solve it ?? For displaying ▶, use \u25b6 (for displaying ▷, use \u25b7 ). Tested on a 2.2 (Froyo) emulator: works . This is a very useful resource: http://unicode-table.com/en

Android EditText Memory Leak

由 拜拜、爱过 提交于 2019-11-30 07:31:33
Alot of people are noticing EditText in an activity is holding a Strong Reference to an Activity even once its finished. To be clear this EditText is inside a layout and inflated, there is no Listeners set. This only happens on certain devices e.g. Samsung Galaxy S4 (Android 4.2.2) and others. Many post about this still no solution. First here is some useful posts. (Eventually GC will clean this so its not technically a leak, but for heavy memory apps it takes way to long and will cause OOM) Android Samsung Memory leak in EditText Why does EditText retain its Activity's Context in Ice Cream
