自定义仿微信支付输入密码方框样式输入框

效果图如下

思路： linearLayout里嵌入textview用于显示数字     上盖一层透明的editText 监听输入事件，当没输入时  光标可显示 ，长安用于粘贴复制过的数字    输入后数字后  光标消失。

NumberEditText ：

public class NumberEditText extends LinearLayout {

  /** 输入框 */
  private TextView[] inputTv = new TextView[7];
  /** 用于接受键盘输入内容 */
  private EditText invisibleEt;
  /** 输入结束监听 */
  private OnInputFinishListener onInputFinishListener;

  public NumberEditText(Context context) {
    super(context);
    createView(context);
  }

  public NumberEditText(Context context, AttributeSet attrs) {
    super(context, attrs);
    createView(context);
  }

  public NumberEditText(Context context, AttributeSet attrs, int defStyleAttr) {
    super(context, attrs, defStyleAttr);
    createView(context);
  }

  @TargetApi(Build.VERSION_CODES.LOLLIPOP)
  public NumberEditText(Context context, AttributeSet attrs, int defStyleAttr, int defStyleRes) {
    super(context, attrs, defStyleAttr, defStyleRes);
    createView(context);
  }

  private void createView(Context context) {
    View view = LayoutInflater.from(context).inflate(R.layout.lemon_number_edittext, null);
    inputTv[0] = (TextView) view.findViewById(R.id.lemon_number_edittext_tv0);
    inputTv[1] = (TextView) view.findViewById(R.id.lemon_number_edittext_tv1);
    inputTv[2] = (TextView) view.findViewById(R.id.lemon_number_edittext_tv2);
    inputTv[3] = (TextView) view.findViewById(R.id.lemon_number_edittext_tv3);
    inputTv[4] = (TextView) view.findViewById(R.id.lemon_number_edittext_tv4);
    inputTv[5] = (TextView) view.findViewById(R.id.lemon_number_edittext_tv5);
    inputTv[6] = (TextView) view.findViewById(R.id.lemon_number_edittext_tv6);
    invisibleEt = (EditText) view.findViewById(R.id.lemon_number_edittext_et);
    invisibleEt.addTextChangedListener(new InvisibleEtTextWatcher());
    addView(view);
  }

  public void setOnInputFinish(OnInputFinishListener listener) {
    this.onInputFinishListener = listener;
  }

  public void clearText() {
    int tvLength = inputTv.length;
    for (int i = 0; i < tvLength; i++) {
      inputTv[i].setText("");
    }
    invisibleEt.setText("");
  }

  /**
   * 处理从edittext到textview
   */
  private class InvisibleEtTextWatcher implements TextWatcher {
    @Override
    public void beforeTextChanged(CharSequence s, int start, int count, int after) {}

    @Override
    public void onTextChanged(CharSequence s, int start, int before, int count) {}

    @Override
    public void afterTextChanged(Editable s) {
      String text = s.toString().trim();
      char[] chars = text.toCharArray();
      int length = chars.length;
      if (length > 0) {
        invisibleEt.setCursorVisible(false);
      } else {
        invisibleEt.setCursorVisible(true);
      }
      int tvLength = inputTv.length;
      for (int i = 0; i < tvLength; i++) {
        if (i < length) {
          inputTv[i].setText("" + chars[i]);
        } else {
          inputTv[i].setText("");
        }
      }
      if (onInputFinishListener != null) {
        onInputFinishListener.onInputFinish(text);
      }
    }
  }

  public interface OnInputFinishListener {
    void onInputFinish(String text);
