最佳答案

在您的应用程序中使用此代码，它对我有用:

DevicePolicyManager devicePolicyManager =
             DevicePolicyManager.getSystemService(Context.DEVICE_POLICY_SERVICE);
ComponentName demoDeviceAdmin = new ComponentName(this, name of activity);

devicePolicyManager.setPasswordQuality(
             demoDeviceAdmin,DevicePolicyManager.PASSWORD_QUALITY_UNSPECIFIED);
devicePolicyManager.setPasswordMinimumLength(demoDeviceAdmin, 5);

boolean result = devicePolicyManager.resetPassword("123456",
             DevicePolicyManager.RESET_PASSWORD_REQUIRE_ENTRY);

Toast.makeText(this,
             "button_lock_password_device..."+result,
             Toast.LENGTH_LONG).show();
