仿QQ6.1手势锁
项目地址：https://github.com/103style/QQ6.1GestureLock
该项目是仿照当前版本的QQ手势锁，主要实现设置手势锁和检验手势锁的功能。
废话不多说 先上效果图。
主界面代码：
public class MainActivity extends AppCompatActivity implements View.OnClickListener{ public static String password; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); ViewUtils.inject(this); }
@OnClick({R.id.bt, R.id.btCheck}) @Override public void onClick(View v) { switch (v.getId()){ case R.id.bt: startActivity(new Intent(MainActivity.this, SetGestureLockActivity.class)); break; case R.id.btCheck: if (password == null){ Toast.makeText(MainActivity.this,"请先设置手势锁",Toast.LENGTH_SHORT).show(); }else{ Intent intent = new Intent(MainActivity.this, CheckActivity.class); intent.putExtra("password",password); startActivity(intent); } break; } } }
设置手势密码代码：
public class SetGestureLockActivity extends Activity { // 手势密码点的状态 public static final int POINT_STATE_NORMAL = 0; // 正常状态 public static final int POINT_STATE_SELECTED = 1; // 按下状态 public static final int POINT_STATE_WRONG = 2; // 错误状态 @ViewInject(R.id.lock_indicator) LockIndicator mLockIndicator; @ViewInject(R.id.text_tip) TextView mTextTip; @ViewInject(R.id.gesture_container) FrameLayout mGestureContainer; private GestureContentView mGestureContentView; private boolean mIsFirstInput = true; private String mFirstPassword = null; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_set_gesture_lock); ViewUtils.inject(this); initParam(); } private void initParam() { mGestureContentView = new GestureContentView(this, false, "", new GestureDrawline.GestureCallBack() { @Override public void onGestureCodeInput(String inputCode) { if (!isInputPassValidate(inputCode)) { mTextTip.setText(Html.fromHtml("<font color='#c70c1e'>最少链接4个点, 请重新输入</font>")); mGestureContentView.clearDrawlineState(0L); return; } if (mIsFirstInput) { mFirstPassword = inputCode; updateCodeList(inputCode); mGestureContentView.clearDrawlineState(0L); } else { if (inputCode.equals(mFirstPassword)) { Toast.makeText(SetGestureLockActivity.this, "设置成功", Toast.LENGTH_SHORT).show(); mGestureContentView.clearDrawlineState(0L); MainActivity.password =mFirstPassword; SetGestureLockActivity.this.finish(); } else { mTextTip.setText(Html.fromHtml("<font color='#ff0000'>与上一次绘制不一致，请重新绘制</font>")); // 左右移动动画 Animation shakeAnimation = AnimationUtils.loadAnimation(SetGestureLockActivity.this, R.anim.shake); mTextTip.startAnimation(shakeAnimation); // 保持绘制的线，1.5秒后清除 mGestureContentView.clearDrawlineState(1300L); } } mIsFirstInput = false; } @Override public void checkedSuccess() { }
@Override public void checkedFail() { } }); // 设置手势解锁显示到哪个布局里面 mGestureContentView.setParentView(mGestureContainer); updateCodeList(""); } private void updateCodeList(String inputCode) { // 更新选择的图案 mLockIndicator.setPath(inputCode); } private boolean isInputPassValidate(String inputPassword) { if (TextUtils.isEmpty(inputPassword) || inputPassword.length() < 4) { return false; } return true; } }
检验手势密码代码：
public class CheckActivity extends AppCompatActivity { @ViewInject(R.id.text_tip) TextView mTextTip; @ViewInject(R.id.gesture_container) FrameLayout mGestureContainer;
private GestureContentView mGestureContentView; //设置的手势密码 private String password; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_check); ViewUtils.inject(this); Intent intent = getIntent(); password = intent.getStringExtra("password"); Log.e("Password", password); initViews(); } private void initViews() { // 初始化一个显示各个点的viewGroup mGestureContentView = new GestureContentView(this, true, password, new GestureDrawline.GestureCallBack() { @Override public void onGestureCodeInput(String inputCode) { } @Override public void checkedSuccess() { mGestureContentView.clearDrawlineState(0L); Toast.makeText(CheckActivity.this, "密码正确", 1000).show(); CheckActivity.this.finish(); } @Override public void checkedFail() { mGestureContentView.clearDrawlineState(1300L); mTextTip.setVisibility(View.VISIBLE); mTextTip.setText(Html .fromHtml("<font color='#ff0000'>密码错误</font>")); // 左右移动动画 Animation shakeAnimation = AnimationUtils.loadAnimation(CheckActivity.this, R.anim.shake); mTextTip.startAnimation(shakeAnimation); } }); // 设置手势解锁显示到哪个布局里面 mGestureContentView.setParentView(mGestureContainer); } }
