代码调用系统复制粘贴板

              //获取剪贴板管理器：ClipboardManager cm = (ClipboardManager) getSystemService(Context.CLIPBOARD_SERVICE);
// 创建普通字符型ClipDataClipData mClipData = ClipData.newPlainText("Label", "这里是要复制的文字");
// 将ClipData内容放到系统剪贴板里。cm.setPrimaryClip(mClipData);

自定义textview

public class SelectableTextView extends AppCompatTextView {private SelectableTextHelper mSelectableTextHelper;private int selectedColor;private int cursorHandleColor;public SelectableTextView(Context context) {super(context);}public SelectableTextView(Context context, @Nullable AttributeSet attrs) {super(context, attrs);init(context,attrs);}public SelectableTextView(Context context, @Nullable AttributeSet attrs, int defStyleAttr) {super(context, attrs, defStyleAttr);init(context,attrs);}private void init(Context context,AttributeSet attrs){TypedArray ta = context.obtainStyledAttributes(attrs, R.styleable.SelectableTextView);selectedColor = ta.getColor(R.styleable.SelectableTextView_selected_color, ContextCompat.getColor(context,R.color.colorAccent));cursorHandleColor = ta.getColor(R.styleable.SelectableTextView_cursor_handle_color, ContextCompat.getColor(context,R.color.colorAccent));mSelectableTextHelper = new SelectableTextHelper.Builder(this).setSelectedColor(selectedColor).setCursorHandleSizeInDp(20).setCursorHandleColor(cursorHandleColor).build();}public void setSelectedColor(int selectedColor) {this.selectedColor = selectedColor;}public void setCursorHandleColor(int cursorHandleColor) {this.cursorHandleColor = cursorHandleColor;}}
