项目地址：[https://github.com/103style/QQ6.1GestureLock](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;
