推荐答案

一个EditText控件中的文本的对齐方式可以通过重力控制：

Alignment of text within an EditText widget can be controlled via gravity:

editText.setGravity(Gravity.TOP);

要附加标记对象的EditText上的内容，您可以使用编辑接口：

To attach markup objects to the EditText's content you can use the Editable interface:

EditText editText = (EditText) findViewById(R.id.editview);
SpannableStringBuilder builder = new SpannableStringBuilder();
builder.append("one red word");
builder.setSpan(new ForegroundColorSpan(Color.RED), 4, 7, Spanned.SPAN_COMPOSING);
editText.setText(builder, BufferType.EDITABLE);
