Answer 2

仅使用标准颜色代码的变体：

android:textColor="#ff0000"

以TEXTVIEW的XML格式添加

或使用

textview.setTextColor(color);

Answer 3

SpannableStringBuilder builder = new SpannableStringBuilder();

String red = edittext.getText().toString();
SpannableString redSpannable= new SpannableString(red);
redSpannable.setSpan(new ForegroundColorSpan(Color.RED), 0, red.length(), 0);
builder.append(redSpannable);

mTextView.setText("Total Records to be SYNC : "+builder+"\nDo you want sync all records...!", BufferType.SPANNABLE);

Answer 4

您可以使用以下代码，我已经过测试，并且它的工作正常。

String value1 = "Total Records to be SYNC : ";
String value2 = "\nDo you want sync all records...!";
String valueFromEdittext = edittext.getText().toString();
String finalValue = value1 + valueFromEdittext + value2;
Spannable WordtoSpan = new SpannableString(finalValue);
WordtoSpan.setSpan(new ForegroundColorSpan(Color.RED), value1.length(), (value1 + valueFromEdittext).length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
mTextView.setText(WordtoSpan);
