Android: Center text inside EditText programmatically
提问by capcom
Is there any way to center the inputted text in an EditTextfield? More specifically, instead of the cursor starting at the left of the box, it should start in the center and move outward towards the left as it is populated with inputs.
有没有办法将输入的文本集中在一个EditText字段中？更具体地说，光标不应从框的左侧开始，而应从中心开始，并在填充输入时向外向左移动。

you should use
你应该使用
textView.setGravity(Gravity.CENTER_HORIZONTAL);

Try android:gravity="center_horizontal"in the widget definition in your layout file. This will not strictly "move outward towards the left" -- it should move outward in both directions evenly. If you truly mean you want the text to only be on the left side of the EditText, I doubt that will be possible.
android:gravity="center_horizontal"在布局文件中尝试小部件定义。这不会严格地“向左向外移动”——它应该在两个方向上均匀地向外移动。如果您真的希望文本仅位于 的左侧EditText，我怀疑这是否可行。

Simpler Solution to align text in EditText is to add android:gravity="center" in layout xml. There is no need to add Java code.
在 EditText 中对齐文本的更简单解决方案是在布局 xml 中添加 android:gravity="center"。无需添加 Java 代码。
